Best supplement tracker apps in 2026
Some apps help you shop. Others focus on food, daily doses, or testing whether a change made a difference. The table compares each app's stated research focus, daily log, and on/off testing.
| App | Research focus | Daily log | On/off test |
|---|---|---|---|
| Biostacks | Cited research and stack analysis | Supplement doses | Structured on/off trials |
| SuppCo | Product discovery, trust ratings, and shopping | Supplement routine | Not stated |
| Prove It | Barcode scans and research-based product reviews | Not stated | Not stated |
| Supplements AI | Scheduling and stack suggestions | Supplement doses | Not stated |
| Cronometer | Food and nutrient intake | Food and nutrients | Not stated |
Descriptions are based on each app's linked official site or store listing, checked October 2026. “Not stated” means we did not find the feature in that source; it does not prove the app lacks it. Features and prices can change.
Which one should you try?
For food and micronutrient intake, start with Cronometer. To research a product before buying it, look at Prove It or SuppCo. For reminders and a guided schedule, look at Supplements AI. If you want cited stack findings and a structured on/off experiment using your own metrics, try Biostacks.
Biostacks is made by Hmujo LLC, which published this comparison. It does not tell you what to take or replace advice from a clinician.
