# Units vs Auguscope

The clearest difference is in-app purchases: Auguscope at none against Units's 3. Auguscope also leads on ads (none vs shown). Units's advantage is ratings volume (150 vs 4) and review sentiment (60% vs 50%). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. Units sells 3 one-off in-app purchases. Auguscope asks for nothing beyond the download.

Auguscope holds the better App Store score, 3.8 against 3.6. That said, the two scores are not equally well evidenced: Units has 150 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 60% of Units's written reviews are positive against 50% of Auguscope's, so the app with the better star average is not the one people write more warmly about.

Units ships an update monthly, Auguscope every 3 weeks. The most recent releases landed on September 25, 2026 and September 3, 2026 respectively.
