# Kindoo vs e

The clearest difference is rating: e at 5.0 against Kindoo's 3.4. Kindoo's advantage is ratings volume (38 vs 3) and monetization model (free vs ad-supported). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

e holds the better App Store score, 5.0 against 3.4. That said, the two scores are not equally well evidenced: Kindoo has 38 ratings behind it against 3, so its average is the more settled of the two.

Kindoo ships an update monthly, e every 2 months. The most recent releases landed on September 9, 2026 and September 19, 2026 respectively.
