Verdict
The clearest difference is price: CathSource at Free against BP Recorder's $2.99. CathSource also leads on rating (1.6 vs 1.0) and ratings volume (23 vs 1). BP Recorder's advantage is review sentiment (75% vs 43%) and chart position (#195 vs unranked). On update cadence, ads, in-app purchases and monetization model 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
CathSource is free to download; BP Recorder costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
CathSource holds the better App Store score, 1.6 against 1.0. That said, the two scores are not equally well evidenced: CathSource has 23 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 43% of CathSource's written reviews are positive against 75% of BP Recorder's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on September 18, 2026 and August 24, 2026 respectively.
