Issues

The app relies on Webogram. Using websockets would increase the app's performance. Also the app's size is quite big (transferred size 853KB).

The contest task is completed. The design of the app is partially different in specific details to the design of the provided mockups: e.g. the bold font on the login screen.

The following deficiencies were identified during the testing:

Login screen:
– Entering country prefix makes the country set as Unknown;
– Search issues (not possible to find Koreas by 'Korea', Germany by 'man', etc.);
– The phone number is being edited on the code screen, which is not correct. Once you start editing the phone number, you should be redirected to the login screen.

Chats screen:
– Sloppy on rendering profile pictures, reloading the page helps;
– A bit slow on loading chat history;
– Profile pictures overlap each other when messages contain unsupported media. 

One major issue was discovered in Safari: the app jumps after opening a chat, the input field appears and disappears, the scroll's behavior is unpredictable.

We recommend to focus on optimizations and decreasing the amount of initially downloadable code, since this has prevented the app from being promoted to a higher place.

- +1 is no always Canada, as +7 is not always KZ.
- Phone number is not formatted
- Native browser autocomplete should probably be disabled on Country input

Good work. A couple of issues:

- in phone input: return key doesn't do anything
- "we have sent you an SMS" - the text is always like this, even if a telegram message/phone call was sent
- not responsive

When return to a chat which was already visited, the content is not automatically scrolled to a last/unread message, but instead it shows the old history and begin to append older messages.
Strange glitch with a time (screenshot attached).
