Verdict
The clearest difference is in-app purchases: Prime Factorization at none against Bambu Handy's 3. Prime Factorization also leads on review sentiment (100% vs 88%) and iOS requirement (8.0 vs 16.0). Bambu Handy's advantage is rating (4.8 vs 4.4) and update cadence (every 11 days vs every 3 months). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Bambu Handy sells 3 one-off in-app purchases. Prime Factorization asks for nothing beyond the download.
Bambu Handy holds the better App Store score, 4.8 against 4.4. That said, the two scores are not equally well evidenced: Bambu Handy has 40K ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Prime Factorization's written reviews are positive against 88% of Bambu Handy's, so the app with the better star average is not the one people write more warmly about.
Prime Factorization ships an update every 3 months, Bambu Handy every 11 days. The most recent releases landed on October 15, 2026 and October 31, 2026 respectively.
