Verdict
The clearest difference is review sentiment: Sleep Time at 76% against Sleepace's 21%. Sleep Time also leads on rating (4.7 vs 1.9) and ratings volume (5.4K vs 29). Sleepace's advantage is in-app purchases (none vs 10) and ads (none vs shown). On price, update cadence and device support there is nothing between them.
