# Deer Anatomy vs VoltLab

The clearest difference is price: VoltLab at Free against Deer Anatomy's $3.99. VoltLab also leads on rating (5.0 vs 2.0) and update cadence (every 6 days vs every 119 months). Deer Anatomy's advantage is in-app purchases (none vs 7). On review sentiment, ads and device support there is nothing between them.

VoltLab is free to download; Deer Anatomy costs $3.99 up front. VoltLab sells 7 in-app purchases, starting at $3.99 per month. Deer Anatomy asks for nothing beyond the download.

VoltLab holds the better App Store score, 5.0 against 2.0. That said, the two scores are not equally well evidenced: VoltLab has 381 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Deer Anatomy's written reviews are positive against 97% of VoltLab's, so the app with the better star average is not the one people write more warmly about.

Deer Anatomy ships an update every 119 months, VoltLab every 6 days. The most recent releases landed on September 14, 2026 and October 12, 2026 respectively.
