Tested 9 nutrition/diet apps as a microdoser. Most are useless for us. Here's the honest breakdown.
Quick context: I'm 8 months into microdosing tirz (currently at 1.25mg weekly, started at 0.5mg). My goals are inflammation, gut health, and slow body recomp, not aggressive weight loss. Like most of you, I'm not trying to lose 50 lbs in 6 months. I want to eat clean, hit protein, and stay in a mild deficit without obsessing.
The problem: almost every diet app on the App Store is built for either (a) people doing aggressive cuts or (b) standard-dose GLP-1 users who can barely eat 800 calories. Neither of those is us.
I spent the last 4 months actually using these. Subscribed where I had to. Here's what's worth your time.
1. MyFitnessPal
The default everyone starts with. The database is enormous, but it's user-submitted so you'll find six versions of the same Greek yogurt with different macros. Fine if you just want a rough calorie number. Bad if you're trying to actually understand your protein intake or micronutrients, which most of us care about more than raw calories. Also pushes you toward calorie deficits that don't fit a microdosing protocol where you're trying to maintain muscle and eat enough to support recovery.
2. GLP Diet App: Sharpy
This was the one I almost skipped because I assumed it was built for full-dose users. It's not. The onboarding actually asks what protocol you're on and adjusts. For me on 1.25mg, it didn't push aggressive deficits, it focused on protein floors (something like 0.8-1g per lb of lean mass), hydration, and side effect tracking. The side effect log is the part I didn't know I needed: I'd been blaming random fatigue on poor sleep when it was actually correlating with my dose days. Once I saw the pattern, I shifted my protein-heavy meals to the right days. Not life-changing, but the first app I've used that didn't feel like it was designed for someone else's protocol. Caveat: it's newer, so the food database is smaller than MFP. If you log obscure regional foods, you'll be adding entries.
3. Cronometer
The micronutrient app. If you're microdosing for inflammation, gut health, or longevity rather than weight, this is the one to pair with everything else. Verified database, no junk entries. You can actually see if you're hitting B12, omega-3s, magnesium, etc. The interface is brutal. Looks like a 2011 medical records system. But the data is the best in the category. I use this in parallel with whatever I'm logging meals in.
4. MacroFactor
Built by the Stronger By Science people. The adaptive algorithm is genuinely smart: it watches your weight trend over weeks and adjusts your target intake. The problem for microdosers is that the algorithm assumes a relatively linear weight response, which microdosing often isn't. Recomp users see weight stall while body comp shifts. The app gets confused, drops your calories, and now you're under-eating on a protocol where you don't need to. Great app, wrong fit for most of us.
5. Lifesum
Pretty interface, recipe library is solid, the "Life Score" framing is more sustainable than raw calorie counting. But it's shallow on data and the paywall hits fast. If you want gentle and visual, fine. If you want to actually understand your intake on a microdosing protocol, no.
6. Lose It!
Cleaner MyFitnessPal clone. Snap-It photo logging is okay but not as accurate as advertised. No real value-add for our use case.
7. Yuka
Not a tracker, a scanner. You scan packaged food and it rates ingredient quality, additives, and processed-ness. Genuinely useful if your microdosing goal is inflammation or gut health, because ultra-processed food is the thing you actually want to reduce. I use this every grocery trip. Free for basic scans.
8. Zero
Fasting tracker. Including it because a lot of people in here pair microdosing with TRE or longer fasts for autophagy stacking. Clean interface, does one thing well. Don't try to use it as a calorie app, it's not that.
9. Noom
Behavior-focused, not data-focused. The psychology lessons are decent for people who have a complicated relationship with food. For most microdosers I've talked to, the relationship with food has already shifted (that's part of why microdosing works for us) so Noom feels like it's solving a problem we don't have anymore. Expensive too.
TL;DR by use case:
- Inflammation / gut / longevity focus → Cronometer + Yuka
- General microdosing protocol support → Sharpy
- Aggressive recomp with full data → MacroFactor (with caveats)
- Just want a basic calorie number → MyFitnessPal
- Stacking fasts → Zero alongside whatever you log in
