# AUMI vs Skoog Skratch

The clearest difference is rating: AUMI at 5.0 against Skoog Skratch's 4.1. Skoog Skratch's advantage is review sentiment (75% vs 50%) and update cadence (every 5 weeks vs every 6 months). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

AUMI holds the better App Store score, 5.0 against 4.1. Both are backed by a comparable volume of ratings — 4 and 9 respectively. Written reviews complicate that: 50% of AUMI's written reviews are positive against 75% of Skoog Skratch's, so the app with the better star average is not the one people write more warmly about.

AUMI ships an update every 6 months, Skoog Skratch every 5 weeks. The most recent releases landed on September 25, 2026 and October 20, 2026 respectively.
