Verdict

The call

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.
