Deadline: 23:59 on October 5th (Dubai time)
Who can participate: Everyone
Results: October 19th, 2023
Telegram is hosting a new design contest for its Android app.
The Task:
Create a detailed redesign concept for the Telegram Android app. Your concept should maintain the app’s core essence and lightweight feel while introducing an improved visual aesthetic with updated elements.
The guidelines of Material Design 3 may also be used for additional reference. To be eligible for any rewards, your submission must include all the areas and components outlined below.
Minimum Requirements:
Chat List
• Bottom Navigation Bar
Chats
• Private Chats (including Secret Chats)
• Channels (both admin and subscriber perspectives)
• Groups (including those with topics enabled)
Profiles
• User Profiles
• Group and Channel Info pages
Settings
• Main Settings Page
• User Info
Your design should thoroughly consider various scenarios and encompass all related elements and components – such as pinned messages, service messages, shared media, stories and more.
For the Chat List you can include an optional version with a white header (and an alternate translucent appearance).
Submission Format:
1) The layouts can be implemented as static .png files. For any animation demos, use .mp4 format (without sound).
Source files and properly structured Figma projects are also welcome.
2) If you include videos, you must also provide several static .png images from each video that serve as a storyboard.
3) If you use complex animated icons, they must be in lottie json or .tgs format.
Submissions that include detailed visualizations, such as videos showcasing your project from a general perspective and offering in-depth views of elements like transition flows between screens and interface animations (including buttons) are more likely to receive a higher place in the prize rankings.

We are happy to announce that Dreamy Crab and Subtle Piranha put in a tremendous amount of work following the Telegram X Competition results.
Both developers have continued to polish their apps with help from the TgX Communtity. The fixes and improvements they made are now merged into the Telegram X Beta – so everyone can try the following features:
• Channel Comments + Message Threads
• The ‘Send As’ feature
• Improved Search
We have awarded both contestants the remaining 30% of their prizes, per the distribution criteria: $3,300 to Dreamy Crab and $2,700 to Subtle Piranha.
🏆 Telegram X Android Competition, Round 2: Results
In this round, there were 11 contestants who contributed to 3 separate features for Telegram X:
Channel Comments + Message Threads – 4 submissions
The ‘Send As’ feature – 5 submissions
Improved Search – 4 submissions
While we strongly advised focusing on a single feature to achieve the highest level of quality, several competitors did try 2 or even all 3. We were pleasantly suprised by the skills of Dreamy Crab, who succeeded in implementing 2 well-polished features.
As stated in the announcement, there is only a single nomination per feature – each of the contestants listed below will shortly receive a 70% payout. For the next 2 weeks they can continue improving their apps and fixing any bugs with the help of the Telegram X community once they arrive on the beta. After that, they will receive the remaining 30% of their prize.
While testing the submissions and evaluating the entries' code, we focused on the following criteria: code consistency, overall app stability and how precisely the the provided design was followed.
Here are the winners:
⭐️ Dreamy Crab – $7,700 (70% of $7,000 + $4,000)
• The ‘Send As’ feature
• Improved Search
(The remaining $3,300 will be paid after the community testing phase.) This entry will be available soon on @tgx_log.
⭐️ Subtle Piranha – $6,300 (70% of $9,000)
• Channel Comments + Message Threads
(The remaining $2,700 will be paid after the community testing phase.) This entry can be tested from @tgx_log – and your bug reports are welcome in @tgandroidtests.
The judges unanimously noted 2 other entries – we would like to award ✨Modest Dolphin a bonus prize of $1,000 for a solid attempt at implementing the ‘Send As’ feature. ✨Busy Raсcoon also earns $1,000 for their implementation of Channel Comments – they added a beautiful animation for previewing comments.
All are welcome to check the reviews for each submission, now available on contest.com
Congratulations to the winners and stay tuned for more Telegram X Competitions.
ContestBot is also ready to accept submissions for the iOS Contest.
Choose “iOS Contest 2022”, answer the bot’s questions, then send it a .zip archive that contains the following:
1. The source code of your app, together with a step-by-step guide for the build process. Tools like brew and similar are allowed, just make sure you properly indicate this.
2. An .ipa file for your app signed with any certificate.
Note: You must make sure your app can be built from your provided sources and enclosed build instructions – on a clean instance of macOS 12.6 or 13 with only Xcode installed. Entries that fail to do so will not be considered for the competition.

🤖 Telegram Mini App Contest
Prize fund: $50,000
Deadline: 23:59 on October 9th (Dubai time)
Who can participate: Everyone
Results: October 31st, 2023
Telegram is launching a contest for developers of Mini Apps like this one. One of the goals of this competition is to create a variety of examples and reusable tools for future Mini App developers.
The Task:
The task is to build any useful Mini App for Telegram and publish its client and server code on Github.
Your submission must include:
• A GitHub repository containing the source code of your example Mini App, built from scratch. You can use any programming language for the server-side code. The source code of your app must be easy to understand and reusable for any developer starting to build Mini Apps for Telegram. For more, see the “Mini App requirements” section below.
• Comprehensive and organized documentation in English, including a setup guide. Ensure the guide addresses every element of your solution, and the documentation details all potential errors and exceptions. It should be written in a user-friendly way that is approachable even for inexperienced developers. Translations in other languages are welcome too.
---
Mini App requirements:
• Design a simple yet functional app. For reference, see @DurgerKingBot or @wallet.
• Your solution should include at least one fully functional Mini App example. Example apps are allowed to showcase fictional services or generate placeholder data, such as creating a mock store.
• It is strictly prohibited to implement a browser view of actual webpages, the Mini App must be a separate entity built from scratch solely for its purpose. For example a "Weather App" submission that only provides a browser view for an existing weather website is not allowed. That said, actual webpages are allowed for authorization flows where a user is required to sign up or log in to use the service.
• Recommended Mini App categories include games, dating, community management, venue booking, e-commerce, сontent editing, etc.
• Each additional Mini App example can qualify for extra rewards, but only if it represents a different app category.
Evaluation Criteria:
We will evaluate each submission's code and documentation quality from the developer perspective, as well as its example Mini Apps from the user perspective. The app should be useful for developers, users, or both.

@ContestBot will begin accepting submissions at a later date. We will further clarify the submission instructions closer to the deadline.

🏆 Telegram iOS Contest 2022, Round 1: Results
We were pleased to see 68 developers, both newcomers and accomplished contest veterans, participate in this competition to implement a feature-rich media editor from scratch.
For such a complex task with a tough deadline, many contestants delivered solid apps. However, no submissions in this round qualified for🥇1st place. For this reason, we will be giving smaller rewards to a larger than usual number of apps. Congratulations to the winners – the number of people on today’s podium indicates a growing community of skilled programmers.
Remember, winning Telegram Contests is the only way to join the Telegram Team.
When evaluating the entries, we first rated how well an app implemented the minimum requirements, then separately reviewed any of its extra features. Smooth, high-quality drawing was the top priority.
🥈2nd and 🥉3rd Place were reserved for submissions that achieved the minimum requirements, while apps that were close to the criteria but lacked polish and stability were awarded 🎖4th Place.
After many hours of testing and deliberation, we are now ready to announce the results. Everyone is welcome to check the detailed reviews for each app on contest.com. Here are the winners!
