Yes, there is no Y-scale animation, only X-scale one.

— The app is slow when scaling and filtering.
— Incorrect values on Y-scale when filtering the third chart.
— Missing filtering animations to the last graph.

View with values can be placed outside the screen. Sum gives 99% percents only. Columns on bar chart do not animate too.

Dates have weird scaling behavior.

Header range always displays full range of the chart.
Crashes on iPhone 5
wrong minimum
Major: dates do not change opacity smoothly, they have just 3 states in opacity. Furthermore, when you scale graph fast, dates positions animate with much lower fps. Not only the UX is suffering, but also it gives this contestant a major advantage in performance over other participants.
Dates are overlapped
iPhone 5S, iOS 12.2
Dates are redrawn on certain positions.

Y-axis labels animate with strange transformations, x-axis labels do not animate and it's possible to see them in 50% alpha state. Chart lines do not animate. Pan gesture does not work for view with values.

What do you mean saying 'x-axis labels do not animate'? Could you provide a video?

Can't move tooltip - only tap. Very hard click on sliders at left/right position.

Wrong Y values, + yellow chart values get updated when blue is hidden

Does not support iOS 8. Telegram does.
No filter toggle animation on all charts
Critical: 26 fps during bar chart scrolling on iPhone 5S. For more details read my comments about performance of entry213.
