# iSilo vs Dropbox

The clearest difference is price: Dropbox at Free against iSilo's $9.99. Dropbox also leads on rating (4.8 vs 3.8) and ratings volume (916K vs 50). iSilo's advantage is in-app purchases (none vs 11) and iOS requirement (8.0 vs 17.0). On update cadence, ads and device support there is nothing between them.

Dropbox is free to download; iSilo costs $9.99 up front. Dropbox sells 9 in-app purchases, starting at $6.99 per month. iSilo asks for nothing beyond the download.

Dropbox holds the better App Store score, 4.8 against 3.8. That said, the two scores are not equally well evidenced: Dropbox has 916K ratings behind it against 50, so its average is the more settled of the two.

iSilo ships an update every 3 weeks, Dropbox fortnightly. Both last shipped on October 14, 2026.
