# Uplode vs Ninja

The clearest difference is in-app purchases: Uplode at none against Ninja's 11. Ninja's advantage is ratings volume (11K vs 3) and iOS requirement (13.4 vs 17.6). On price, rating, update cadence and ads there is nothing between them.

Both are free to download. Ninja sells 11 in-app purchases, starting at $2.99 per 7 days. Uplode asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for Uplode against 4.9 for Ninja. That said, the two scores are not equally well evidenced: Ninja has 11K ratings behind it against 3, so its average is the more settled of the two.

Uplode ships an update fortnightly, Ninja every 2 weeks. The most recent releases landed on October 6, 2026 and October 18, 2026 respectively.
