Both are free to download. Cuckoo sells 1 one-off in-app purchase and TimeSignals sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
TimeSignals holds the better App Store score, 4.5 against 3.4. Both are backed by a comparable volume of ratings — 16 and 6 respectively. Written reviews complicate that: 68% of Cuckoo's written reviews are positive against 49% of TimeSignals's, so the app with the better star average is not the one people write more warmly about.
Cuckoo ships an update every 3 months, TimeSignals every 4 weeks. The most recent releases landed on September 19, 2026 and June 10, 2026 respectively.
