Verdict
The clearest difference is in-app purchases: Khmer Physic Formulas at none against OneBookStore's 10. Khmer Physic Formulas also leads on rating (4.4 vs 4.0) and ratings volume (15 vs 1). OneBookStore's advantage is review sentiment (80% vs 50%) and update cadence (every 2 months vs every 19 months). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. OneBookStore sells 10 one-off in-app purchases. Khmer Physic Formulas asks for nothing beyond the download.
Khmer Physic Formulas holds the better App Store score, 4.4 against 4.0. That said, the two scores are not equally well evidenced: Khmer Physic Formulas has 15 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 80% of OneBookStore's written reviews are positive against 50% of Khmer Physic Formulas's, so the app with the better star average is not the one people write more warmly about.
OneBookStore ships an update every 2 months, Khmer Physic Formulas every 19 months. The most recent releases landed on September 24, 2026 and October 13, 2026 respectively.
