Yesterday we stopped accepting new submissions for the March contest. Overall, we received 225 apps for Android, 148 apps for iOS, and 560 apps for Web. This is a large number and we thank everybody for taking part.

We’ll carefully go through each app and make sure every participant receives a short review of their work. We hope that our feedback will allow participants to improve or reconfirm their skills.

After selecting and awarding the winners of this round, we may launch another round to identify the best of the best. We’ll be sharing more news at the end of this week.

The results of the March Android contest have arrived.

Out of the hundreds apps we received for the contest, we aimed to select those that demonstrated the highest speed and performance.

To identify them, we would typically run the 5th graph with four lines (zoomed out, checking / unchecking the red line) on older but popular devices (e.g. Samsung S5, Moto X and Xiaomi Redmi Note 4).

We discarded all the apps that failed to run or had performance issues in these cases. Likewise, we discarded all the apps that displayed each chart on a separate screen, as the contest goal was specifically to show them “on one screen”.

We also had to eliminate all apps that crashed in random cases. As a result, we selected one winner - @thankyou2. The app of this 26 y.o. engineer from St. Petersburg is the only one that runs fast and stable on all our devices and complies with the design guidelines.

@thankyou2 will receive $50,000 from Telegram.

We also have a runner-up – @where_is_s - who will receive $10,000 from Telegram. The app of this 30 y.o. engineer from Novosibirsk has fewer glitches and is almost as fast as @thankyou2’s.

We invite all participants of this contest to take part in the next and final stage of the Chart Coding Contest that starts this Saturday, on the 6th of April. Its prize budget will be another $150,000.

Tomorrow we will continue announcing the winners of the March Contest and sending you feedback on your apps.

Stay tuned – we’ll soon publish the list of Android developers who won the third prize, as well of the winners of the JS and iOS contest.

And some more good news: We are substantially increasing the overall prize budget of the 3 coding contests (Android, JS, iOS) to appreciate the large number of good apps.

We are happy to announce the remaining winners of the Android contest. In addition to our earlier post, we are rewarding 7 developers with a third prize and 18 developers with a fourth prize.
