Verdict
The clearest difference is monetization model: MetabolicTracker at free against Core Change's free with in-app purchases. MetabolicTracker also leads on update cadence (every 10 days vs every 4 weeks). Core Change's advantage is ratings volume (51 vs 2) and iOS requirement (16.0 vs 26.2). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
On the App Store both sit at effectively the same score — 4.9 for Core Change against 5.0 for MetabolicTracker. That said, the two scores are not equally well evidenced: Core Change has 51 ratings behind it against 2, so its average is the more settled of the two.

Core Change ships an update every 4 weeks, MetabolicTracker every 10 days. The most recent releases landed on October 5, 2026 and October 3, 2026 respectively.
