# SpecimenPro vs Unum

The clearest difference is in-app purchases: Unum at none against SpecimenPro's 1. Unum also leads on ratings volume (21 vs 1) and iOS requirement (15.1 vs 18.6). SpecimenPro's advantage is update cadence (every 3 days vs fortnightly). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. SpecimenPro sells 1 one-off in-app purchase. Unum asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for SpecimenPro against 5.0 for Unum. That said, the two scores are not equally well evidenced: Unum has 21 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

SpecimenPro ships an update every 3 days, Unum fortnightly. The most recent releases landed on October 28, 2026 and November 9, 2026 respectively.
