Verdict
The clearest difference is in-app purchases: Mango 5Star at none against iTer's 1. Mango 5Star also leads on review sentiment (94% vs 60%) and ratings volume (14 vs 1). iTer's advantage is update cadence (every 4 days vs every 2 months) and rating (5.0 vs 4.7). On ads, monetization model, device support and iOS requirement there is nothing between them.

iTer costs $0.99 and Mango 5Star $2.99 up front. iTer sells 1 one-off in-app purchase. Mango 5Star asks for nothing beyond the download.
iTer holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mango 5Star has 14 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 60% of iTer's written reviews are positive against 94% of Mango 5Star's, so the app with the better star average is not the one people write more warmly about.
iTer ships an update every 4 days, Mango 5Star every 2 months. Both last shipped on October 26, 2026.
