# Friedrich vs iFLO PRO

The clearest difference is review sentiment: iFLO PRO at 67% against Friedrich's 0%. iFLO PRO also leads on device support (3 vs 1). Friedrich's advantage is rating (4.6 vs 3.7) and update cadence (monthly vs every 4 months). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Friedrich holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: Friedrich has 53 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 0% of Friedrich's written reviews are positive against 67% of iFLO PRO's, so the app with the better star average is not the one people write more warmly about.

Friedrich ships an update monthly, iFLO PRO every 4 months. The most recent releases landed on October 17, 2026 and October 5, 2026 respectively.
