Verdict
The clearest difference is ads: PSL at none against Ophthalmic Instruments's shown. PSL also leads on update cadence (every 3 months vs every 34 months) and monetization model (free vs ad-supported). On price, in-app purchases, device support and iOS requirement there is nothing between them.
