# VPOP® PRO vs Vetcalculators

The clearest difference is review sentiment: VPOP® PRO at 83% against Vetcalculators's 43%. VPOP® PRO also leads on monetization model (free with in-app purchases vs subscription) and rating (5.0 vs 4.7). Vetcalculators's advantage is ratings volume (618 vs 7) and chart position (#67 vs unranked). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. VPOP® PRO sells 4 in-app purchases, starting at $15.00 per month and Vetcalculators sells 1 in-app purchase, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

VPOP® PRO holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Vetcalculators has 618 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 83% of VPOP® PRO's written reviews are positive against 43% of Vetcalculators's.

VPOP® PRO ships an update every 4 weeks, Vetcalculators every 2 months. Both last shipped on November 6, 2026.
