Verdict
The clearest difference is in-app purchases: Paperpile at none against みえるタイマー's 1. Paperpile also leads on ads (none vs shown) and iOS requirement (12.0 vs 15.1). みえるタイマー's advantage is update cadence (every 3 days vs every 2 months). On price and device support there is nothing between them.
