Verdict
The clearest difference is in-app purchases: Sleep Note at none against TANREN's 1. Sleep Note also leads on iOS requirement (15.1 vs 17.0). TANREN's advantage is ads (none vs shown) and update cadence (every 2 days vs every 4 days). On price and device support there is nothing between them.
