Colitu iOS
New features, fixes and performance improvements in the Colitu apps.
v5.10.0Latest Adaptive Connect 4
Colitu now picks the server and connection method for you more intelligently, so there is less for you to manage.
New features
- The app picks the server and connection method more intelligently with a small decision model that runs on your device.
- Your own network history stays on the device, and anonymous results from other devices in your city update every hour.
- Servers that fail twice in a row from your network are hidden from the list.
- Ping times are now shown while you are connected too.
- Recommended servers appear first in the list.
- If your operator only lets approved sites through, the app notices and switches to a server that works.
- The masked connection report attached to a support request now includes the engine's decisions.
- A server or connection method you choose yourself is never changed.
v5.9.14 Faster server choice and favourites
The app now tries unreachable servers last, shows your favourites and recent servers at the top. You can reach main settings with one tap from the home screen.
New features
- Automatic mode now tries servers most people in your country cannot reach last, so connecting takes fewer failed attempts.
- Star servers in Locations; your favourites and last picked servers appear at the top and as shortcuts on the home screen.
- Tapping the server you are already connected to keeps the connection running.
- Quick settings on the home screen: kill switch and other main settings are one tap away.
- Accessibility: clearer contrast for faint text, labels for screen readers and a better layout with large text.
v5.9.11 Your passport is now saved to your account
Colitu Passport is now saved to your Colitu account, so you see the same passport on every device where you sign in. The progress already on this iPhone moves to your account by itself the first time you open the new version.
New features
- Colitu Passport is now saved to your Colitu account: you see the same passport on every device where you sign in.
- The progress already on this iPhone moves to your account by itself the first time you open the new version.
- Passport minutes are now counted by our servers from your connection time in each country, so they keep counting even when the app is closed.
- Only the totals per country are kept, never a minute-by-minute record, and they are deleted with your account.
Bug fixes
- Sharing a stamp as a Story picture works again, and saving the picture to Photos no longer closes the app.
- The passport no longer runs inside the VPN connection, which keeps the connection lighter.
v5.9.10 Colitu Passport and pings while connected
Colitu Passport is now on your iPhone: stay connected to a country and its stamp opens, with collections and expeditions to explore. You can also see server pings while connected, and the connection uses less memory.
New features
- Colitu Passport: stay connected to a country for 5 minutes and its stamp opens in your passport. Open it from the Passport card on the home screen.
- Stamps level up from Bronze to Silver, Gold and Diamond: on each day you use Colitu, the 10th and 60th minute add a piece to the stamp of the country you are connected to (at most two pieces a day).
- Collections, hidden achievements, weekly expeditions, passport covers and a second chapter of countries.
- Compare passports with a friend by QR code, and share your passport as a Story picture.
- Your passport stays only on this iPhone: it is not linked to your account and nothing is sent unless you turn on the anonymous counters yourself.
- Server pings are now shown while you are connected too, measured on your own network as before.
Bug fixes
- Diagnostic reports sent to support are always created fresh.
Performance improvements
- Passport minutes keep counting while the phone is locked with the VPN on and through short reconnects.
- The connection uses less memory, so iOS has fewer reasons to stop it.
- Fewer false connection checks right after the phone wakes up.
v5.9.8 One-tap invites and company name on the account screen
You can now share your invite link in one tap and see your company name on the account screen.
New features
- After your first connection the home screen shows an invite card; send your invite link to Telegram or WhatsApp in one tap.
- Your friend gets 7 days of Premium and you get 7 days when the invite counts.
- You can hide the invite card.
- Invites from family members or flatmates who share your internet connection now count too (up to 2 a month).
- There is a new "Review our browser extension" row in the account screen.
- The account screen shows your company name when your account uses a Colitu Business seat; the company manages the seat.
v5.9.7 Internet works again on every server
Some iPhones showed "Connected" while websites and apps did not open. This update fixes that, so the internet works again on every server.
Bug fixes
- Fixed some iPhones showing "Connected" on every server while websites and apps did not open.
- Name lookups on your iPhone now go through the VPN reliably, as they did before.
- Ad blocking keeps working as before: with it on, ads and trackers are still filtered.
- Name lookups still travel inside the encrypted VPN connection.
v5.9.6 No more "connected but nothing loads"
On some networks the app showed "Connected" while nothing loaded. Now the app checks that real traffic gets through and reconnects on its own if needed.
New features
- While you are connected, the app now downloads a small test file to make sure real traffic gets through.
- If the test fails twice in a row, the app marks the connection method as not working on this network and reconnects with the next one on its own, usually within about half a minute.
- The app remembers the result for this network, so the next connection starts with a method that works there.
Bug fixes
- Fixed: on some networks the app showed "Connected" while websites and apps did not load.
Performance improvements
- The test only runs while the app is open and almost no data is arriving, and never while data is already flowing.
v5.9.5 Websites keep loading when a lookup server is briefly unreachable
If the encrypted name lookup server can't be reached, the app now notices within about ten seconds and switches to the previous way of looking up names. Pages keep opening in the meantime.
Bug fixes
- Websites keep loading when the encrypted name lookup server cannot be reached: the app now notices within about ten seconds and switches to the previous way of looking up names.
- When the encrypted lookup server can be reached again, the app moves name lookups back to it on its own.
- One lost answer no longer changes how names are looked up: the app checks a second time before switching either way.
- Better connection reports: when a connection check fails, the report now says at which step it failed.
v5.9.4 Fewer drops under heavy use, private name lookups
Connection drops while browsing a lot are reduced, and your address lookups now stay private over one encrypted connection.
Bug fixes
- Fewer connection drops when you browse a lot; address lookups now share one encrypted connection.
- Your address lookups go encrypted to Colitu's own servers, which keep no log of them.
- With ad blocking on, address lookups go to the ad-blocking servers.
- If those servers can't be reached, the app switches back to the previous lookup method on its own, so browsing keeps working.
v5.9.3 Connections stay open when you lock your screen or switch networks
Your connections no longer drop when you lock your phone or move between Wi-Fi and mobile data. The app now checks whether the connection still works and only restarts it when it has really stopped.
Bug fixes
- Locking the screen no longer cuts your connections, so messages, calls and downloads no longer drop after a short sleep.
- Switching between Wi-Fi and mobile data no longer cuts your connections while the previous network is still available.
Performance improvements
- The "Resilient" connection method now uses less memory, so the system no longer has to restart the connection to free memory.
- The fastest connection method is tried again even after another method worked on your network before.
v5.9.2 Faster connections and safer TV sign-in
First connections now set up in seconds, connections restart right after your phone wakes up, and TV sign-in asks for your password or two-step verification code.
New features
- The first connection to a new server now sets up within a second or two.
- If the server hasn't confirmed yet, the app retries the same server every 2 seconds.
- Approving a TV sign-in now asks for your password or your two-step verification code.
Bug fixes
- After your phone wakes up, a connection that went stale is restarted right away.
- On slow networks, ad blocking gives up after 3 seconds and uses a backup answer.
- The order of servers and connection methods in automatic mode follows the same shared rules as every Colitu app.
- Adaptive Connect is being rolled out gradually.
- Better reports of failed connections and recoveries are sent; no visited sites are included.
v5.9.1 Fewer drops, connection reports and security
This version reduces drops during long sessions, helps support resolve connection issues faster, and improves security.
New features
- Fewer drops on long sessions: the VPN uses less memory under heavy use, so iOS no longer has to stop it, and it recovers better after a network change or when the internet is briefly gone.
- Connection reports for support: when our support team looks into a connection problem on your account, the app sends a connection report (app and device details, connection events and the app's own logs) the next time it opens. The names and addresses of the sites you visit are masked on your device before anything is sent, and masked again on our side; reports are deleted after 90 days.
- When you open a support conversation with "attach diagnostics" on, the full connection report is attached automatically, so support can help without asking you for logs.
- Support for a connection mode that changes ports regularly, which keeps speed up on mobile networks that slow down long-running connections.
Bug fixes
- The automatic connection check no longer uses a service that is slowed down in some regions, and no longer treats a dead connection as healthy.
- Devices you removed no longer come back in the device list.
- Clear messages when an account is waiting for a review or a sign-up is refused, instead of a generic error.
- Your app language is now shared with your account, so e-mails, notices and support replies arrive in the language you use. Server and city names are shown in your language as well.
- Locations have calmer, roomier rows; pings are not measured through the tunnel.
- Security hardening from independent audits.
- Updated connection engine and libraries.
- Connections on long sessions are steadier: a server-side fix stops an unfinished upload (for example an aborted speed test) from freezing the fast connection mode; this helps every app version, including this one.
v5.8.0 Stronger protection for your account
Colitu now communicates with the service only using certificates from trusted authorities. This prevents certificates added by someone else from reading your sign-in or session.
v5.7.0 Adaptive Connect 2.0 and Warm Spare
Fastest server now truly picks the fastest server, and if your connection drops, it switches to a backup within seconds. Also, new users get a simple mode and in-app messages.
New features
- Adaptive Connect 2.0: Fastest server now really picks the fastest server by measuring ping on your network.
- Warm spare: While connected, a backup path on another server is kept ready and traffic moves to it within seconds if the main path fails.
- Faster connecting on difficult networks: The best two paths are tried at the same time, and in automatic mode the app skips a server that does not work.
- If a server you picked yourself fails, a 'Try the fastest server' button appears.
- The connection is watched on every method, and the app reconnects by itself after unexpected drops.
- Simple mode and Advanced mode: New installations start in Simple mode with only the essentials; one tap shows the other options.
- Messages from Colitu inside the app, for example when you are close to your monthly data limit.
Performance improvements
- In a one-hour test with 11 deliberately injected failures, the connection was available 98.8% of the time; when the server was cut completely for 101 seconds, the user saw a pause of about 5 seconds.
v5.6.0 Steadier calls on the Fast connection and privacy mode by default
In the new version, calls and long sessions on the Fast connection are more stable. Also, new installations now send all traffic through the VPN by default.
New features
- Calls and long sessions on the Fast connection are now more stable: on servers that support it, the app changes its network port every 30 seconds.
- If the Fast connection stalls while your internet still works, the app moves that server to the next connection method for 10 minutes by itself.
- When the Colitu website cannot be reached from your network, the app finds the Colitu service through a signed list of alternative addresses, so signing in and loading servers keep working.
- New installations send all traffic through the VPN (privacy mode). Letting regional sites bypass the VPN is now an option you turn on yourself. Existing installations keep their current setting.
- Signing in from an unusual location can ask for a 6-digit code sent to your e-mail, to protect your account.
- Clearer messages when a sign-up is refused: temporary e-mail addresses, passwords found in known data breaches, and too many sign-ups from one network.
v5.5.1 Servers grouped by country and a more compact list
Servers are now grouped by country and the list is more compact. Countries with one server stay a single row, and search still lists every matching server.
New features
- Servers are grouped by country: a country with several servers shows one row with the number of locations and the best ping.
- Tap a country to see its cities; countries with one server stay a single row.
- Search still lists every matching server.
- The server list is more compact: about twice as many servers fit on one screen.
- Tags show in full and long country names are no longer cut off.
v5.5.0 Block internet without VPN and new features
This version lets you keep your device offline when the VPN is off and keeps IPv6 traffic inside the VPN. It also adds split tunneling, two-step sign-in and double VPN.
New features
- A new switch keeps your iPhone or iPad offline whenever the VPN is not connected.
- It is off by default because hotel and airport Wi-Fi sign-in pages can't open while it is on.
- You can now choose sites and IP addresses that bypass the VPN or the only ones that use it.
- Colitu asks for the authenticator code at sign-in if two-step verification is on.
- Multihop routes and rotating IP are available with some connection methods.
Bug fixes
- IPv6 traffic no longer leaves outside the VPN.
Performance improvements
- A clear "Use this device instead" screen appears when your plan allows fewer devices.
- A notice appears before a trial ends.
v5.4.1 Privacy and security update
This release has no new features; privacy and security were improved. The app no longer sends any usage data or crash reports.
New features
- Google Firebase Analytics and Crashlytics have been removed.
- The app now only talks to Colitu.
- The source code of the iOS app is now public on GitHub.
- Links from messages, websites or QR codes can no longer add settings to the app.
- The home-screen shortcut "Start VPN" was removed.
- Your sign-in is no longer copied to another phone through a backup.
- Signing out removes the connection settings, logs and diagnostics from the phone.
- Other apps can no longer use the VPN's internal connection.
- Diagnostics reports now hide passwords, keys, links with credentials and e-mail addresses.
- Russian sites with the Moscow server now go through the VPN.
Bug fixes
- A Wi-Fi login page or an error page from your network no longer signs you out.
- Switching between Wi-Fi and mobile data no longer briefly drops the VPN.
- Signing out can no longer get stuck, and removing this device asks only once.
- The password length rule now applies only to registration.
- Large images in support chat load faster and attachments are checked before they are opened.
v5.4.0 Ad blocking and a new server label
Colitu can now block ads and trackers. You can turn it on or off in your Account settings.
New features
- A new "Ad blocking" switch is in Account → Features. It is off by default.
- When it is on, ads and trackers are blocked in every app by Colitu's own DNS servers, on every server you connect to.
- No query log is kept on these servers.
- If a site or an app stops working properly, turn the switch off; the connection restarts by itself when you change it.
- Servers that run Colitu's ad-blocking DNS (Sweden, United Kingdom, Poland) carry an "Ad blocking" label in the server list.
v5.3.12 Faster server switching and a new server list
This release fixes server switching issues and refreshes the server list. You can now connect faster and choose servers more easily.
New features
- The new server list has a "Fastest server" button next to the title, search, categories with icons, and sorting by ping, name or load.
- "Recommended" servers appear first, followed by "All servers".
- Each location shows its round country flag, city, ping with signal bars, and which services open there.
Bug fixes
- Switching to another server no longer hangs; the app now waits for the previous connection to fully close before opening the new one.
- If one connection method does not start in time, the app moves on to the next one instead of giving up.
- Switching after a long pause no longer shows "Your session ended", and you stay signed in.
v5.3.10 A new connection method and more reliable connecting
Colitu now offers a fifth way to connect to servers and tries more options before giving up. This means fewer connection problems, especially on mobile networks.
New features
- Every Colitu server now offers a fifth connection method called Resilient.
- Resilient carries the tunnel as ordinary HTTPS requests and keeps working on mobile networks that slow down long connections.
- The app chooses Resilient by itself when other methods do not get through; there is nothing to set up.
Bug fixes
- If a connection method does not carry traffic, the app now tries every method the server offers before giving up.
- The Fast method is also tried when its quick check does not answer; this fixes 'could not connect' on some mobile networks.
- The diagnostics report no longer contains broken lines.
