# ACVIM vs ACVR

The clearest difference is review sentiment: ACVIM at 25% against ACVR's 0%. ACVIM also leads on ratings volume (140 vs 25). ACVR's advantage is rating (4.7 vs 4.4). On price, update cadence, ads and in-app purchases there is nothing between them.

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

ACVR holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: ACVIM has 140 ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 25% of ACVIM's written reviews are positive against 0% of ACVR's, so the app with the better star average is not the one people write more warmly about.

Both ship on a similar rhythm, roughly every 12 months. The most recent releases landed on September 28, 2026 and October 4, 2026 respectively.
