TODO

  • Accessibility

App Store

  • Application main features was released during Telegram contest from June 25 to July 4.

  • The application was published in App Store in August 2021 (after two weeks review).

  • In Semptember new updates were blocked due the Guideline 4.3 - Design

    Same feature set as other apps submitted to the App Store

  • In November Telegram paid 750$ for the 3rd place in the Sticker App Contest.

  • In January 2022 I've decided to Open Source it.

The application is still in App Store and available for free but will not receive any updates because of the App Store vague rules.
