# Fitlight vs PEER

The clearest difference is rating: PEER at 5.0 against Fitlight's 3.4. PEER also leads on review sentiment (100% vs 61%). Fitlight's advantage is in-app purchases (none vs 10) and update cadence (fortnightly vs every 4 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. PEER sells 10 one-off in-app purchases. Fitlight asks for nothing beyond the download.

PEER holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Fitlight has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 61% of Fitlight's written reviews are positive against 100% of PEER's.

Fitlight ships an update fortnightly, PEER every 4 months. The most recent releases landed on October 3, 2026 and October 6, 2026 respectively.
