# OptoFitting vs Lens

The clearest difference is review sentiment: OptoFitting at 100% against Lens's 44%. OptoFitting also leads on rating (5.0 vs 4.4) and ads (none vs shown). Lens's advantage is ratings volume (1.3K vs 1) and update cadence (every 2 weeks vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. OptoFitting sells 2 in-app purchases, starting at $19.99 per month and Lens sells 4 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

OptoFitting holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: Lens has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of OptoFitting's written reviews are positive against 44% of Lens's.

OptoFitting ships an update monthly, Lens every 2 weeks. Both last shipped on November 3, 2026.
