Verdict

The call

The clearest difference is price: COOLSIS Family Access at Free against LessonBook's $4.99. COOLSIS Family Access also leads on device support (3 vs 1) and iOS requirement (13.0 vs 16.4). LessonBook's advantage is update cadence (fortnightly vs every 4 months). On ads and in-app purchases there is nothing between them.
