# Window vs FastLog

The clearest difference is rating: Window at 4.5 against FastLog's 2.0. Window also leads on ratings volume (11K vs 1) and device support (4 vs 2). FastLog's advantage is in-app purchases (none vs 10) and review sentiment (50% vs 22%). On price, update cadence, ads and iOS requirement there is nothing between them.

Both are free to download. Window sells 9 in-app purchases, starting at $4.99 per 7 days. FastLog asks for nothing beyond the download.

Window holds the better App Store score, 4.5 against 2.0. That said, the two scores are not equally well evidenced: Window has 11K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 22% of Window's written reviews are positive against 50% of FastLog's, so the app with the better star average is not the one people write more warmly about.

Window ships an update monthly, FastLog fortnightly. The most recent releases landed on November 11, 2026 and November 3, 2026 respectively.
