Your menstrual cycle changes everything. Your calorie tracker doesn't know that.
Oli reads your cycle phase from Apple Health and adjusts your daily calorie and macro targets automatically, every phase, every day. Nothing to track by hand and no spreadsheets to keep.
Every nutrition app treats every day the same, even your period.
Calories on day one of your period. Calories on day fourteen. Same number. Same macros. Same indifference. Your body's nutritional needs shift across your menstrual cycle. No tracker accounts for that.
Generic targets.
MyFitnessPal gives you the same 1,800 calories on day 1 of your period as day 14. Your body doesn't work that way: energy needs, cravings, and metabolism all shift across your cycle.
No menstrual cycle awareness.
No mainstream tracker connects to your Apple Health period data to move your targets with it. The cycle data exists on your phone. They've never used it.
The hardest days get the same number.
If you live with endometriosis or adenomyosis, some days of the month are nothing like the others. Your tracker has no idea which day it is, so it hands you an identical target on all of them.
Three steps. Then it runs itself.
Set it up once. Open the app on day twelve of your menstrual cycle and your numbers have already moved with you. No manual phase logging. No period diary. No spreadsheets.
Connect Apple Health.
Oli reads your cycle tracking data the same way your iPhone does. No manual input, no extra logging, no third-party services in the middle.
Oli maps your phase.
Each day is tagged: menstrual, follicular, ovulatory, or luteal. The boundaries scale to your own cycle length rather than a textbook 28 days, and Apple Health's recorded end of your period overrides the estimate.
Targets update daily.
Wake up to macros and calories already tuned to where you are. Log what you eat. The math is done. You're free to think about anything else.
What changes across your cycle, and why.
Your menstrual cycle is really four windows of metabolism, energy, and hormone load. Oli holds a calorie and macro profile for each one. The AI Target Coach proposes all four from a sentence about you, you review and save them, and your daily number glides between them.
- Calories eased back
- Protein held steady
- Carbs kept moderate
- A recovery week, lower output
- Calories back toward baseline
- Higher carbs supported
- Protein held steady
- Rising energy
- Highest calorie window
- Protein supported at peak output
- Carbs held high
- Peak energy
- Calories nudged up
- A little more fat alongside them
- Carbs held steady
- Progesterone rise, higher resting burn
Those five numbers are what Oli moves: calories, protein, carbs, net carbs and fat. Oli does not track micronutrients, so the food and nutrient side of each phase lives on the guides instead, with the research behind it: menstrual, follicular, ovulatory and luteal.
Set your targets once. Oli retunes them for every phase.
Flip on cycle tracking and your numbers split into four phase profiles. Tell the AI Target Coach about yourself and it fills in calories and macros for menstrual, follicular, ovulatory and luteal, or type them in by hand. Point it at Apple Health and the right profile loads automatically, every morning.
Endometriosis, adenomyosis, and the days that are harder.
Women with endometriosis and adenomyosis know how differently one week of the month can go from the next. Oli does not treat any of that, and it will not tell you which foods to eat for it. What it does is stop pretending the month is flat: it reads where you are in your cycle and moves your calorie and macro targets with you, so the days that knock you sideways are not being measured against the same number as the good ones.
Ask Oli anything about your period, your cycle, and your plate.
The Ask tab is an AI nutrition coach that can see your cycle phase, your logged meals and your remaining macros. Ask it "what should I eat today to ease cramps?" or "how much protein do I have left?" and the answer comes back built around your day rather than around an average.
General nutrition information, not medical advice. For anything about a diagnosis or a treatment, talk to your clinician.
What Oli tracks: calories, protein, carbohydrates, net carbs and fat, with a separate target profile for each cycle phase. It does not track micronutrients such as iron or magnesium, it does not track symptoms, and nothing in the app is tailored to a diagnosis. Anything about food and a specific condition is a question for the Ask coach, which returns general nutrition information, or for your own clinician. Oli is not a medical provider and nothing on this page is medical advice.
