# Visual Attention Therapy vs PSL

The clearest difference is price: PSL at Free against Visual Attention Therapy's $19.99. PSL also leads on rating (5.0 vs 4.7) and update cadence (every 3 months vs every 6 months). Visual Attention Therapy's advantage is ratings volume (486 vs 1) and chart position (#199 vs unranked). On ads, in-app purchases and device support there is nothing between them.

PSL is free to download; Visual Attention Therapy costs $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

PSL holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Visual Attention Therapy has 486 ratings behind it against 1, so its average is the more settled of the two.

Visual Attention Therapy ships an update every 6 months, PSL every 3 months. The most recent releases landed on October 17, 2026 and October 10, 2026 respectively.
