# ファイルサイズチェッカー vs RabbitBox

The clearest difference is rating: ファイルサイズチェッカー at 5.0 against RabbitBox's 4.4. ファイルサイズチェッカー also leads on review sentiment (75% vs 33%) and in-app purchases (none vs 3). RabbitBox's advantage is update cadence (fortnightly vs every 9 months) and ratings volume (5 vs 1). On price, ads and device support there is nothing between them.

Both are free to download. RabbitBox sells 3 in-app purchases, starting at $0.99 per month. ファイルサイズチェッカー asks for nothing beyond the download.

ファイルサイズチェッカー holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: RabbitBox has 5 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 75% of ファイルサイズチェッカー's written reviews are positive against 33% of RabbitBox's.

ファイルサイズチェッカー ships an update every 9 months, RabbitBox fortnightly. The most recent releases landed on October 22, 2026 and October 24, 2026 respectively.
