Verdict
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 (#181 vs unranked). On ads, in-app purchases and device support there is nothing between them.
