Verdict

The call

The clearest difference is price: Optics Trainer at Free against Brain Tool Kit's $17.99. Optics Trainer also leads on ratings volume (305 vs 6) and update cadence (every 8 days vs monthly). Brain Tool Kit's advantage is ads (none vs shown) and review sentiment (86% vs 67%). On in-app purchases, device support and iOS requirement there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Optics Trainer holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Optics Trainer has 305 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 67% of Optics Trainer's written reviews are positive against 86% of Brain Tool Kit's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Optics Trainer ships an update every 8 days, Brain Tool Kit monthly. Both last shipped on October 25, 2026.
