# AppStash vs Frequency Generator

The clearest difference is rating: Frequency Generator at 5.0 against AppStash's 3.3. Frequency Generator also leads on in-app purchases (none vs 1) and update cadence (every 6 days vs every 12 months). AppStash's advantage is ratings volume (7 vs 1) and iOS requirement (9.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. AppStash sells 1 one-off in-app purchase. Frequency Generator asks for nothing beyond the download.

Frequency Generator holds the better App Store score, 5.0 against 3.3. That said, the two scores are not equally well evidenced: AppStash has 7 ratings behind it against 1, so its average is the more settled of the two.

AppStash ships an update every 12 months, Frequency Generator every 6 days. Both last shipped on October 3, 2026.
