# BP Doctor vs ePEF

The clearest difference is in-app purchases: ePEF at none against BP Doctor's 3. ePEF also leads on review sentiment (18% vs 10%). BP Doctor's advantage is rating (2.2 vs 1.8) and ratings volume (57 vs 11). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. BP Doctor sells 3 in-app purchases, starting at $5.90 per month. ePEF asks for nothing beyond the download.

BP Doctor holds the better App Store score, 2.2 against 1.8. That said, the two scores are not equally well evidenced: BP Doctor has 57 ratings behind it against 11, so its average is the more settled of the two. Written reviews complicate that: 10% of BP Doctor's written reviews are positive against 18% of ePEF's, so the app with the better star average is not the one people write more warmly about.

BP Doctor ships an update every 4 weeks, ePEF every 6 weeks. The most recent releases landed on September 12, 2026 and September 17, 2026 respectively.
