# Ediag vs Besure AI

Ediag and Besure AI both sit at 4.3 stars, but that hides the real split: 68% of Besure AI's written reviews are positive against 30% of Ediag's. Besure AI also leads on update cadence (every 2 days vs every 2 months) and chart position (#134 vs unranked). Ediag's advantage is in-app purchases (none vs 12) and ratings volume (1.5K vs 207). On price, rating, ads and device support there is nothing between them.

Both are free to download. Besure AI sells 12 in-app purchases, starting at $9.99 per month. Ediag asks for nothing beyond the download.

Besure AI holds the better App Store score, 4.5 against 4.3. That said, the two scores are not equally well evidenced: Ediag has 1.5K ratings behind it against 207, so its average is the more settled of the two. Written reviews point the same way: 30% of Ediag's written reviews are positive against 68% of Besure AI's.

Ediag ships an update every 2 months, Besure AI every 2 days. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
