Verdict
The clearest difference is in-app purchases: Weight Trekker at none against GLP1 Tracker's 2. Weight Trekker also leads on review sentiment (83% vs 50%). GLP1 Tracker's advantage is rating (4.7 vs 4.3) and update cadence (every 4 days vs every 3 weeks). On price, ratings volume, ads and device support there is nothing between them.

GLP1 Tracker holds the better App Store score, 4.7 against 4.3. Both are backed by a comparable volume of ratings — 28 and 33 respectively. Written reviews complicate that: 83% of Weight Trekker's written reviews are positive against 50% of GLP1 Tracker's, so the app with the better star average is not the one people write more warmly about.
Weight Trekker ships an update every 3 weeks, GLP1 Tracker every 4 days. The most recent releases landed on October 30, 2026 and November 8, 2026 respectively.
