Verdict

The call

The clearest difference is in-app purchases: Keystone at none against SimpleTime's 3. Keystone also leads on iOS requirement (17.0 vs 26.0). SimpleTime's advantage is update cadence (every 5 days vs fortnightly) and device support (3 vs 1). On price and ads there is nothing between them.
