Verdict

The call

The clearest difference is ads: Minimal Zen Wallpaper at none against Study Timer's shown. Minimal Zen Wallpaper also leads on update cadence (every 3 weeks vs every 5 months). Study Timer's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price and in-app purchases there is nothing between them.
