Verdict

The call

The clearest difference is review sentiment: Stupid Simple Macro Tracker at 65% against Cal AI's 32%. Stupid Simple Macro Tracker also leads on iOS requirement (15.0 vs 18.0). Cal AI's advantage is ratings volume (366K vs 7.9K) and update cadence (weekly vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Stupid Simple Macro Tracker sells 13 in-app purchases, starting at $6.99 per month and Cal AI sells 19 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Cal AI holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: Cal AI has 366K ratings behind it against 7.9K, so its average is the more settled of the two. Written reviews complicate that: 65% of Stupid Simple Macro Tracker's written reviews are positive against 32% of Cal AI's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Stupid Simple Macro Tracker ships an update monthly, Cal AI weekly. The most recent releases landed on September 23, 2026 and September 25, 2026 respectively.
