# Bi vs EMDR

The clearest difference is in-app purchases: Bi at none against EMDR's 7. Bi also leads on review sentiment (62% vs 46%). EMDR's advantage is update cadence (weekly vs every 2 months) and ratings volume (172 vs 28). On price, rating, ads and iOS requirement there is nothing between them.

Both are free to download. EMDR sells 6 in-app purchases, starting at $4.99 per month. Bi asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.3 for Bi against 4.4 for EMDR. That said, the two scores are not equally well evidenced: EMDR has 172 ratings behind it against 28, so its average is the more settled of the two. Written reviews are what separate them: 62% of Bi's written reviews are positive against 46% of EMDR's.

Bi ships an update every 2 months, EMDR weekly. The most recent releases landed on October 9, 2026 and October 20, 2026 respectively.
