The call

The clearest difference is in-app purchases: SleepBytes at none against NightWatch's 1. SleepBytes also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.0). NightWatch's advantage is update cadence (monthly vs every 3 months). On price and device support there is nothing between them.
