Verdict

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. CashLens sells 6 in-app purchases, starting at $2.99 per month. Flow asks for nothing beyond the download.
Flow holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 20 and 6 respectively. Written reviews complicate that: 95% of Flow's written reviews are positive against 100% of CashLens's, so the app with the better star average is not the one people write more warmly about.
Flow ships an update every 2 weeks, CashLens monthly. The most recent releases landed on September 21, 2026 and September 18, 2026 respectively.
