I just want to report that Ratio running smoothly on both devices I own as main (S9+) and backup (PH-1). One is with Exynos and the other with SD835.
Just a note, please add an option to change the font size. A slider like Small - Medium - Large - XL would be good with 3-5 pixel increments of the font size.
Keep up the good work! We’re here for you.
