# WarfarinGuide vs MAPPP

The clearest difference is review sentiment: WarfarinGuide at 90% against MAPPP's 50%. MAPPP's advantage is rating (4.2 vs 3.8) and update cadence (every 4 months vs every 11 months). On price, ratings volume, 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.

MAPPP holds the better App Store score, 4.2 against 3.8. Both are backed by a comparable volume of ratings — 5 and 5 respectively. Written reviews complicate that: 90% of WarfarinGuide's written reviews are positive against 50% of MAPPP's, so the app with the better star average is not the one people write more warmly about.

WarfarinGuide ships an update every 11 months, MAPPP every 4 months. The most recent releases landed on July 25, 2026 and September 10, 2026 respectively.
