🏆 iOS Contest, Round 2 (watchOS): Results
The WatchOS competition was unusual for us – unlike most of our contests, it hasn’t yielded any high-quality or even functioning apps. Despite that, we're sticking to our commitment to distribute ~$50,000 among the winners.
Here are the results of the Second Round of the iOS Contest:
1st PLACE – $20,000
🥇Hip Hyena – This app includes most of the required features and can run on a real Apple Watch. It supports viewing chats (including a wide range of media) as well as sending messages and stickers. It can handle chats with large numbers of messages fairly well.
2nd PLACE – $10,000
🥈Noble Puma – This app can also run on a real Apple Watch. It supports a limited list of features, including logging in, viewing the chat list and displays text messages in chats. The app fails to display profile photos or media in chats.
3rd PLACE – $7,000
🥉Fairy Turtle – Implemented viewing messages in chats, including certain types of media. Also did some work on the Settings screens.
Penalties (-$2,000):
– Simulator only, doesn't run on real devices
🥉Perfect Wasp – Implemented viewing messages in chats, including certain types of media. The app also supports sending messages (with the exception of stickers and locations).
Penalties (-$2,000):
– Simulator only, doesn't run on real devices
4th PLACE – $4,000
🎖Huge Kiwi
Penalties (-$2,000):
– Simulator only, doesn't run on real devices
🎖Hairy Duck
Penalties (-$2,000):
– Simulator only, doesn't run on real devices
Honorable mentions – $1,000
🏅2176 Merry Goat – The app only allows logging in and viewing the chat list.
🏅2178 Huge Giraffe – Only supports logging in, the chat list can't be viewed.
🏅2179 Sunny Moth – Presents mockup data.

🏆 iOS Contest, Round 3 (watchOS)
The third round of the iOS contest starts now. Everyone can participate, even if they didn't take part in the previous rounds.
The task is the same as in the second round – to create a working watchOS app based on the mockups provided.
Deadline: June 6, 23:59 Dubai time.
Prize fund: $40,000
Who can participate: Everyone. We expect the participants of the second round to improve their submissions. We also invite new participants to join.
TDLib: Most of the participants of the second round based their apps on TDLib. At that time, TDLib wasn’t optimized to run on WatchOS. We have recently updated TDLib to better support WatchOS. We hope that this will result in a significant improvement in stability and performance of apps submitted in this new round.
The Task:
Create a standalone Telegram app for watchOS 7 in Swift without using third-party UI frameworks (using TDLib is allowed). Bonus points if the app also supports watchOS 6.
The app should support:
- Logging in via QR Code with support for accounts protected by a 2-Step Verification password.
- Viewing the chat list.
- Opening chats with users, groups, channels.
- Viewing messages in chats, including text messages and all types of attachments: photos, videos, files, voice and video messages, locations, contacts, static and animated stickers, polls and quizzes.
- Sending messages via voice message and text, as well as sending current location, stickers, emoji or canned text.
- Sending new messages to existing chats, by replying to notifications, and via the 'New Message' button in the chat list.
- Swiping right in the chat list to open Settings.
- Accessing the Archive and Saved Messages.
- Changing Notification settings.
- Changing Data settings.
- Terminating sessions from the Devices menu.
Your app should run on WatchOS 7. The design implementation should be identical to the mockups (Sketch, PNG).
You are welcome to view the API docs and inspect the source code of Telegram for iOS. The main criteria for us to identify the winners will be the speed and stability of the apps – as well as attention to detail.
The primary objective is to implement viewing messages in chats, sending text messages and push notification support.
We understand that you may not be able to support all the features from our list before the deadline. During evaluation we will note the number of features implemented flawlessly. The largest prizes will be awarded to contestants who implemented the largest number of features without major issues.
Note that features on list are sorted by their relative importance.
Submissions:
Contestants will be able to submit their apps to @ContestBot closer to the end of this round.

🏆 Android Contest, Round 2: Results
We are happy to announce the results of the Android Animations Contest. Meet the winners:
1st PLACE – $8,000
🥇Fit Rhino – Implemented all of the required features except background animations when the device is tilted. Nice job on the Animation Editor and background transitions when returning to the chat list.
2nd PLACE – $6,000
🥈Eager Cat – The app is well-optimized to animate message sending effects on low-performance devices. However, the contestant should have devoted more time to pre-submission testing. While evaluating the app, we faced numerous crashes; for that reason, a penalty of $1,000 has been applied during the final scoring.
Penalties (-$1,000):
– Multiple crashes
🥈Fairy Zebra – This submission features the best-implementation of the Background Animation when the device is tilted – which works great both on low-budget Xiaomi phones and Samsung flagships.
3rd PLACE – $5,000
🥉Sacred Gorilla – In addition to the main task, the contestant has been working on the GIFs sending effect. The submission is affected by some inconsistencies in the design implementation, especially in the Animation Editor.
Penalties (-$200):
– Default package ID.
🥉Dreamy Crab – This is the only submission that includes an attempt to animate the Send button like on the provided mockups.
🥉Gentle Otter – We expected submissions to be better optimized for running on older devices; however, the app is quite solid in other aspects.
Penalties (-$200):
– Default package ID
4th PLACE – $2,000
🎖Modest Dolphin
🎖Desert Falcon
🎖Slim Scorpion
🎖Suave Lion
🎖Gentle Crow
Penalties (-$200):
– Default package ID
🎖Dreamy Eagle
Penalties (-$400):
– Default package ID
– Rebuilding penalty
The following contestants focused on implementing background animations alone and didn't implement any message animations👇
Honorable mentions – $1,500
🏅Cool Hare
🏅Fit Falcon
🏅Sunny Ant
🏅Large Flamingo
Penalties (-$200):
– Default package ID
Detailed comments from our judges for each of the submissions are available on contest.com. Congratulations to the winners!
Stay tuned for the next contest for Android developers starting this summer. The goal will likely be to develop features for the Android X app.

🏆 Sticker App Contest
Status: Results announced
Among other things, today we launched a platform for third-party apps that allow users to create stickers for Telegram (check out the docs).
We'd like to announce a competition for developers: create an Android or iOS app that helps users easily create unique stickers and submit it to @ContestBot before July 4, 23:59 Dubai time.
You can use any idea or design for your app, provided the app is user friendly and gives users an easy way to create new custom stickers for Telegram. The apps can create static or animated stickers (although apps that create animated stickers will be considered more advanced and may get higher prizes). For example, one can create an app that allows users to upload their own photos and add text on top. The app can automatically remove the backgrounds, apply fun effects and import the result to Telegram as stickers.
We will distribute a $50,000 prize budget among the winners. The best part: contestants will retain all rights for the apps they create, so they will be able to launch their apps as independent startups and potentially monetize them.
