No internet connection is required; the app works entirely offline. * Adjust the volume of both the second-hand sound and voice announcements (can be muted) * Set the announcement interval (from every 10 seconds to every hour) * Choose the type of voice used for announcements (female or male) * Supports background playback * Choose the type of announcements (Standard, Simple and Minimal)

Verdict
The clearest difference is price: メモモ at Free against Interval Voice Clock's $1.99. Interval Voice Clock's advantage is ads (none vs shown) and update cadence (every 2 weeks vs every 2 months). On in-app purchases, device support and iOS requirement there is nothing between them.
