What stays free, forever
A tracker is only worth building a habit on if the habit cannot be taken hostage later. The most expensive mistake apps in this category make is the clawback: a feature is free until enough people depend on it, then it moves behind a wall - the barcode scanner, the export button, the history you already filled in yourself. This page is the opposite, written down. The things below are free in Litmus, and they stay free.
Always free
Stacks, doses, reminders, check-ins, and the full history view. The everyday job of the app is never metered. Log a whole morning in a tap, and scroll back over every day of it, on the free tier.
Every product in the catalog, by name or barcode. All 214,788 products from the NIH label database, searchable, free.
Point the camera at a bottle to read it into your stack. Scanning a barcode or a single label to add a product is free and unmetered. (Reading a whole shelf in one photo is the one scan that is a Pro feature - with one free to try.)
What is in a product, from its label. The ingredient lines and forms for any product, straight from the NIH Dietary Supplement Label Database.
Set what you are tracking toward, and get a starter stack for it. Choosing your goals and seeing a plain starting point for them costs nothing.
The whole setup, before you ever see a price. You build a real, working stack and see the app do its job before Litmus asks you for anything.
Everything you have logged, in full, in formats other software can read. One tap, no tier check, no partial file. Your record leaves as cleanly as it went in.
Your logged data is yours
Every dose, check-in, and stack you record, you can view in full and export in full - free, forever. Doses write to Apple Health, so your record lives in your own ecosystem, not our silo. There are no ads, no data sales, and no hostage patterns. If you ever leave, you lose nothing but the app.
What Pro is, exactly
Litmus Pro is not a key to your own data - it is computation on top of it. The free app records and shows; Pro does the heavier analysis:
- Nutrient Insights: your intake totals against reference targets.
- Deep evidence: the full research-paper trail behind an ingredient, linked to PubMed.
- Unlimited stack scans: read a whole shelf at a time, as often as you want (one free to try).
- Personal readouts (beta): what your own numbers say across periods, in the observational register.
- Ask Litmus, unlimited: past the free weekly allowance.
Nothing you already logged is ever behind that line. Pro sells work done on your data, not access to it, and this list is the whole of it.
Why this is on the record
This page sits next to where every number comes from on purpose. The same standard that makes us publish our sources makes us publish our free line: a commitment is only worth anything if it is written where you can hold us to it. If the free tier ever changes, it changes here first, in plain sight, not quietly in an app update.
