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.

Contestants will be able to submit their apps to @ContestBot closer to the end of this round.

Aptitude Test Contest: Results

The results of the Aptitude Test Contest () are here!
This contest was one of the most involved, requiring that participants pass our evaluation tests to take part, and then demanding their constant attention for over 1.5 months.

We have split the entire remaining €250,000 Quiz Contest prize pool among those participants who completed all the tasks:

Participants had to design a set of 30-question Quizzes which tested three aptitude groups:

• English Language

• Mathematical Ability

• Spatial & Logical Thinking

They then reviewed 9 Quizzes from other participants (that's 270 questions) and submitted rebuttals – reflecting on the reviews their work received. Finally, Telegram Judges analyzed the content of each Quiz, its adherence to the rules and its overall usefulness. The quality of Peer Reviews and the validity of Rebuttals was also assessed.

All of these ratings produced a final Contest Score for each Quiz, between 1 and 4.3.
There are 4 reward tiers for this contest, per Quiz:
  • – €3000 – Contest Score 4+
  • – €1500 – Contest Score 3+
  • – €500 – Contest Score 2.1+
  • – €50 – Contest Score 2 and below
Bonuses were awarded for Outstanding Peer Reviews. Penalties were incurred for Unoriginal Content and Low-effort Peer Reviews.
