Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
AvMark holds the better App Store score, 5.0 against 4.4. Both are backed by a comparable volume of ratings — 61 and 13 respectively. Written reviews complicate that: 87% of Кнопка ГДЗ's written reviews are positive against 57% of AvMark's, so the app with the better star average is not the one people write more warmly about.
Кнопка ГДЗ ships an update every 4 months, AvMark every 7 months. Both last shipped on October 24, 2026.
