MacroFactor
Expenditure estimated from intake and the weight trend, with a weekly check-in that adjusts your targets.
Compared
A MacroFactor alternative that also tracks your workouts.
NOTANOTR is an iPhone app, launching soon, that measures your maintenance every week from what you eat and what the scale does, and reads every set, your sleep and your blood work in the same file, with one change every Sunday.
The short answer
Stay with MacroFactor if calories are all you want read.
MacroFactor's nutrition app is built around an expenditure estimate that follows your intake and your weight trend. For training there is MacroFactor Workouts, a second app with its own subscription. NOTANOTR keeps food and training in one file and reads them together.
MacroFactor and MacroFactor Workouts
Two apps that sync body metrics, scale weight and progress photos. Their site says nutrition and training share no coaching at launch.
NOTANOTR
Food, every set, weight, sleep and blood work in one app. The Sunday check-in proposes one change, and it can be about sleep rather than food.
Side by side
Two MacroFactor apps, or one file.
MacroFactor as its own site and help centre describe it. NOTANOTR as its front page does.

Honest limits
What NOTANOTR does not do.
- No AndroidiPhone only, for now. Both MacroFactor apps run on Android.
- Not for beginnersIt reads what you already log. It does not teach you how to train or how to count food.
- Not in the App Store yetIt launches soon. Leave an address on the front page and we tell you when it is live.
- Not freeUSD 39.99 a month or USD 299 a year, with 7 days free (CHF 39.95 or CHF 299 in Switzerland, EUR 39.99 or EUR 299 where the App Store charges in euros). MacroFactor also offers a free trial.
Is NOTANOTR's calorie adjustment the same as MacroFactor's?
No, it is its own. It re-measures your maintenance every week from what you ate and what the scale did, and the Sunday check-in proposes one change with the number behind it. We do not claim it matches MacroFactor’s algorithm.
Can it plan my training?
It logs every set, tracks e1RM per lift, flags a stall and counts weekly sets for 13 muscles against the range your plan aims for. Your coach can send a program, and Claude or ChatGPT can propose one through the connector. Every proposal waits in the app until you apply it.
Why one file instead of two apps?
Because a stall, a short night and a calorie cut often belong to the same week. When food, sets and sleep sit in one file, the weekly change can say which of them to fix.
Can I log food from a photo?
Yes. Photograph a plate, a menu or a label, or type what you ate the way you would say it. It logs to the gram and shows the portion it assumed, so you can correct it.
