A MeAgain alternative that checks your whole stack
Synergy is a MeAgain alternative that logs peptides, GLP-1 medications, and supplements in one place and checks them against each other. Below: what MeAgain states it does, what Synergy adds, and what MeAgain has that Synergy does not. Every fact is from the app's own App Store listing, verified on the date shown.
We make Synergy. "Not stated" means the MeAgain listing does not mention the feature, not that the app cannot do it. Corrections: [email protected].
What MeAgain does, in its own words
MeAgain describes itself as a GLP-1 tracker for shots and pills: dose logging and schedules, food logging by photo, barcode and search, protein, fiber and water tracking, a symptom log for nausea, constipation, reflux and fatigue, progress photos, weight tracking, and Apple Health sync.
What Synergy adds
Made for use, not for show
Log it. See where it went. See what it touches.
Supplements, peptides, and GLP-1s in one cabinet
Everything you take is logged in one place — the weekly shot, the peptides, and the supplements — instead of the shot in one app and the rest in a notes file.
Interaction checks across the whole stack
Synergy checks every item against every other and shows the pairs with documented interactions — synergies to lean into, cautions to watch — each with a plain-language, educational summary. Never a dose.
Scan a label to add it
Point the camera at a supplement label and the item is added, free on every plan.
Side effects, narrowed down
Reacting to something while taking four things? The side-effect analyzer works through the timeline and produces a record you can hand to a clinician.
What MeAgain has that Synergy does not
In-app food logging with photo and barcode recognition and protein, fiber and water targets built around appetite changes. Synergy reads dietary data from Apple Health instead of logging meals itself.
