Verdict
The clearest difference is review sentiment: Anniversary Tracker at 81% against IsTalk's 49%. Anniversary Tracker also leads on ratings volume (2.1K vs 2). IsTalk's advantage is rating (5.0 vs 4.7) and update cadence (every 3 days vs every 9 days). On price, 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
Both are free to download. IsTalk sells 9 in-app purchases, starting at $1.99 per 7 days and Anniversary Tracker sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
IsTalk holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Anniversary Tracker has 2.1K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 49% of IsTalk's written reviews are positive against 81% of Anniversary Tracker's, so the app with the better star average is not the one people write more warmly about.
IsTalk ships an update every 3 days, Anniversary Tracker every 9 days. The most recent releases landed on November 3, 2026 and November 5, 2026 respectively.
