Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Qflow is free to download; Flag Clock costs $2.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Flag Clock holds the better App Store score, 3.5 against 1.0. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 100% of Qflow's written reviews are positive against 33% of Flag Clock's, so the app with the better star average is not the one people write more warmly about.
Qflow ships an update every 3 months, Flag Clock every 4 months. The most recent releases landed on September 16, 2026 and September 23, 2026 respectively.
