Very slow overall.

— 5 seconds delay on start.
— Vertical scrolling is sloppy.
— The app is slow and laggy when scrolling, scaling and filtering.
— Bonus goal is implemented, however zooming is slow.
— Graphs jitter on start on desktops.
iPhone 5S, iOS 12.1; LG Nexus 5X, Android 8.1

Telegram admins, where is my charts? I sent the archive yesterday, the bot accepted and said "Perfect! Would you like to add an URL to your app? Totally OK if not."

I do not see it in the list, what's the problem?
doesn't work at all on chrome macbook OSX mojave
No raw values on info popup on the 5th chart, only %
Incorrect dates when selecting a date on 5th chart - I've selected 18 Sept and got 13 Aug - 23 Aug
test browser zoom 500
Watching zoom transition frame by frame shows that the suggested behavior isn't implemented.

the implemented behaior just rescales base chart to scale of a selected week and dissapears, which is quite easy to achieve
Chrome, Win10
There is a gap appears in the end of a drawing area after some resize/drag of slider bar
The stacked percentage chart seems upside down starting from the lowest values at the bottom. The sizes of the areas are correct though.

Definitely no dislike from me.
