Verdict
The clearest difference is rating: G at 3.8 against Timegrapher's 2.8. G also leads on in-app purchases (none vs 1) and update cadence (every 2 months vs every 8 months). Timegrapher's advantage is review sentiment (55% vs 17%). On price, ads and device support 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
Both are free to download. Timegrapher sells 1 one-off in-app purchase. G asks for nothing beyond the download.
G holds the better App Store score, 3.8 against 2.8. That said, the two scores are not equally well evidenced: G has 845 ratings behind it against 46, so its average is the more settled of the two. Written reviews complicate that: 17% of G's written reviews are positive against 55% of Timegrapher's, so the app with the better star average is not the one people write more warmly about.
G ships an update every 2 months, Timegrapher every 8 months. The most recent releases landed on November 5, 2026 and November 3, 2026 respectively.
