# PAT vs OneScreen

The clearest difference is review sentiment: OneScreen at 100% against PAT's 28%. OneScreen also leads on rating (5.0 vs 3.7) and in-app purchases (none vs 3). PAT's advantage is ratings volume (64 vs 1) and iOS requirement (13.0 vs 16.4). On price, ads and device support there is nothing between them.

Both are free to download. PAT sells 3 in-app purchases, starting at $9.99 per month. OneScreen asks for nothing beyond the download.

OneScreen holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: PAT has 64 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 28% of PAT's written reviews are positive against 100% of OneScreen's.

PAT ships an update monthly, OneScreen every 10 days. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
