What you actually get free
Most apps call something free and mean free for a fortnight, or free with adverts, or free until the part you actually wanted. Kriterion's free tier is the app, used every day, permanently, without paying and without being sold to.
Here is exactly where the line sits.
Free, always
- Unlimited food logging, by hand or by search, across every food database the app uses
- Your whole history, never truncated, never rolled up, never hidden behind an upgrade after a month
- Reading a nutrition label or a scale with your camera, unlimited, and it happens on your phone rather than on our server. There is nothing to meter because nothing is sent
- Ten saved recipes, and editing one never costs you a slot
- Every macro, plus sugar, salt, saturated fat and fibre, on effectively everything, restaurant items included
- Workouts, sets, reps, weights and RIR, logged in full
- Every built-in programme, plus one routine of your own, swappable weekly
- The HIIT timer, counting and beeping with the screen off
- Readiness, and the sleep, heart rate and heart rate variability that feed it, read from Apple Health or Health Connect
- Cycle tracking, feeding readiness and training guidance
- Weight and trend charts
- Export of everything you have logged, whenever you want it, with no date cutoff. Your history is yours to take out, so taking it out is not something we charge for
- The coach: it explains why it has made a call, and it will adapt the session in front of you if you let it. Both permissions are yours, and it never changes anything without saying so first
- A cited reference library, with the sources named rather than implied
- No adverts. Not now, not later, not as a thing we add once there are enough of you
The caps, and why they exist
| Cap | Why |
|---|---|
| Five barcode scans a day | Every scan is a lookup against databases that cost money to query. Five a day covers ordinary use; a big shop does not |
| Ten saved recipes | Enough for the meals you actually repeat. Nobody else gives you ten free, and we raised it from two because capping recipes felt mean |
| One routine of your own | The built-in programmes are unlimited and uncapped, so this only bites if you are writing your own training |
What Premium is for
One line covers it: free tells you what you ate, Premium tells you what you burn.
The free tier gives you a calorie target the way everyone else does, from a formula worked against your own body. Premium is where the formula starts to fade. Every week the app compares what you actually ate against what the scale actually did, and moves its estimate towards what your own body is showing. The more consistent weeks it has, the more it trusts you and the less it leans on the textbook, with the margin printed next to the number and narrowing as you feed it.
It never switches the formula off entirely, and it does not pretend to. Day one it is mostly the textbook; months in it is mostly you.
| Premium adds | What it is |
|---|---|
| Your measured burn rate | Worked from your own data rather than an equation, and it moves as you do |
| The margin, and the self-check | How sure the app is, and its own score for how well its earlier predictions matched your scale |
| The weekly check-in | What changed, why, and what to do about it |
| Deeper analysis | Burn rate charted, energy balance day by day, nutrients over time, measurements and photos |
| Micronutrient depth | The full picture rather than the macros and the seven that are near-complete across the database |
| Coach tone | Three separately written voices rather than the balanced one |
| Training depth | What to lift next, plateau and deload calls, supersets, custom exercises, unlimited routines |
| Scanning past the cap, recipe breakdowns, supplements | The rest of the ceiling lifted |
What nobody gets, at either tier
- Adverts. There is no tier of this app that shows you one
- Your data sold or shared. There is no business model here that depends on knowing what you ate
- Third-party trackers. None, in the app or on this site
- An account. There is nothing to sign into, which means no password to leak and no database of users to breach
What you log stays on your phone. The privacy policy lists the three things that ever leave it, and one of those only happens because you chose to send it.
