Design implemented not in accordance with the contest guidelines. Part of the required animations are missing. Average performance.

Design is not totally correct. Range selection has no arrows, chart lines have incorrect width, fonts do not match, first plot line is placed not on bottom.

Issues on chart #5. Range selection hides borders eventually, range background trims part of the chart, zoom out button looks incorrect.

When zooming out from chart #5 details, main chart disappears. Buttons for hidden columns have incorrect design.

Bad perfomance, design not correct, something happened also that made the trimmer disappear

1. Misalligned zoomed in 4th chart
2. Trimming any zommed chart makes the trimmer disappear after ~2 seconds
3. To zoom in you have to tap exactly on the date, didnt even realise that zoom in is implemented at first

Slider does not appear immediately after launching. It takes some back and forth scrolling to make it show up.

Switching to night mode only changes visible chart. The second one stays in the day mode.

After zooming in the app allows to scroll beyond the chart’s boundaries.

Selection label can get out of screen.

Dates are overlapping. There is no grid line over the dates

— The app is slow when scrolling and zooming.
— The backgrounds of next graphs aren't changing when switching themes. 
— Zoom Out button overlaps dates on iPhone 5s. 
— The app supports iOS 12+ only.

1. Axes in night mode are invisible (see screenshot above)
2.Tooltip doesn't move with the finger, only via tap

After zooming in the fourth chart starts in the middle of the screen. I think it depends on the time zone, as time also doesn’t start from zero.

Percentage colors don’t match value colors. I believe percentages shouldn’t be colored at all by design.

Pie chart has a selectable black box on the right side of the slider. After returning to the percentage chart hidden data types showed up despite being unchecked.

Combined bar/line chart keeps line info after zooming out.

min version 12.0... really? :(

can't move tooltip - only tap. Tap on tooltips after two minutes stopped working on all charts. I can't show bonus goals... Ah! need tap only on date....

Does not support iOS 8. Telegram does.

Major issue: does not support iOS 10.

Critical issue: does not support iOS 11.

Critical: line width is A LOT thinner than it needs to be by design. Beware: it is not some inaccuracy in design, it was made intentionally in order to achieve HUGE advantage in performance over other participants. The thinner your line, the lower CPU/GPU utilization is. I think such apps should be excluded from this contest.
