Slow on start, low FPS when changing time range.

Designs are wrong

Poor performance on scaling

Poor performance.

No ALL row on the stacked bar chart tooltip

+ on all the charts is hard to place the tooltip, you have to tap on the exact point? or move the finger. Anyway, doesnt get place on touch

Edge points of the charts are cut off

Frame rate drop when using both trimmer handles at the same time

Last bars are not visible
Zooming in out causes y axis values to overlap

Pie charts animations are not working, values are rotated on the circle -> hard to read

Zooming in zooms onto wrong dates

Pie chart is not respecting trimming/scrolling
Tooltip on zoomed charts shows disclosure indicator

— Long tap on checkbox buttons doesn't work
— Pie chart doesn't respond to taps
— Y-scale animation starts only after the user did end touching the screen (sometimes the whole chart disappears because of this, see 1st screenshot)
— 3rd chart badge has no 'Total' row (see 2nd screenshot)
— Graphs on main chart and graphs on scroll bar have same line width (according to designer screenshots, main graphs should be 2 times wide)

– The design does not comply with the guidelines.
– The app is slow when scaling the charts.
– The lines are cut in the upper bound values (please kindly see the attached video).

Extra axis line on double axis chart

Does not support iOS 8. Telegram does.

Major issue: does not support iOS 10.

Critical issue: does not support iOS 11.

Critical issue: line width is A LOT thinner than it needs to be by design. Beware: it is not some inaccuracy in design, it is made intentionally in order to achieve HUGE advantage in performance over other participants (if it uses Core Animation) or hide line drawing artefacts (if it uses Metal).

Major issue: glitches after filter toggle

4 fps during 1st chart scaling on iPhone 5S. Definitely, not Metal :)
