# StorageCalculator vs Focus Puller

The clearest difference is rating: StorageCalculator at 4.0 against Focus Puller's 2.9. StorageCalculator also leads on in-app purchases (none vs 1) and iOS requirement (15.6 vs 18.6). Focus Puller's advantage is update cadence (every 2 months vs every 9 months) and review sentiment (50% vs 33%). On price, ads and device support there is nothing between them.

Both are free to download. Focus Puller sells 1 one-off in-app purchase. StorageCalculator asks for nothing beyond the download.

StorageCalculator holds the better App Store score, 4.0 against 2.9. That said, the two scores are not equally well evidenced: Focus Puller has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 33% of StorageCalculator's written reviews are positive against 50% of Focus Puller's, so the app with the better star average is not the one people write more warmly about.

StorageCalculator ships an update every 9 months, Focus Puller every 2 months. The most recent releases landed on November 6, 2026 and November 7, 2026 respectively.
