Comedians challenging a comedy contest cannot see their watch. If an app tell them the time, it's very helpful, so I made it. Maybe you can use this app for a speech in school or office.

Verdict
The clearest difference is in-app purchases: M at none against AizuDeck's 1. M also leads on update cadence (daily vs every 4 days) and iOS requirement (13.0 vs 17.0). On price, ads and device support there is nothing between them.
