Verdict
The clearest difference is in-app purchases: Smart Disk pro at none against みえるタイマー's 1. Smart Disk pro also leads on ads (none vs shown) and iOS requirement (12.1 vs 15.1). みえるタイマー's advantage is update cadence (every 3 days vs every 6 weeks). On price and device support there is nothing between them.
