# Optics Trainer vs Concussion Fix

The clearest difference is ads: Concussion Fix at none against Optics Trainer's shown. Concussion Fix also leads on review sentiment (100% vs 67%) and rating (4.9 vs 4.5). Optics Trainer's advantage is update cadence (every 8 days vs every 6 weeks) and ratings volume (305 vs 13). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Optics Trainer sells 3 in-app purchases, starting at $4.99 per 7 days and Concussion Fix sells 1 in-app purchase, starting at $999.99 per year. Whichever you choose, the download price is not the number that matters.

Concussion Fix holds the better App Store score, 4.9 against 4.5. That said, the two scores are not equally well evidenced: Optics Trainer has 305 ratings behind it against 13, so its average is the more settled of the two. Written reviews point the same way: 67% of Optics Trainer's written reviews are positive against 100% of Concussion Fix's.

Optics Trainer ships an update every 8 days, Concussion Fix every 6 weeks. The most recent releases landed on October 25, 2026 and October 21, 2026 respectively.
