IsleMark costs $1.99 and TimerSheet $0.29 up front. Neither carries in-app purchases, so what you see is what you pay.
TimerSheet holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: IsleMark has 6 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 89% of IsleMark's written reviews are positive against 50% of TimerSheet's, so the app with the better star average is not the one people write more warmly about.
IsleMark ships an update every 2 weeks, TimerSheet every 5 weeks. The most recent releases landed on November 8, 2026 and November 1, 2026 respectively.
