Training Nutrition
One coach for how you train. A different one for how you eat. Each reads only its own side of your day, and both answer to the numbers you logged.
Coming to Google Play. Free while we are in testing, with 14 days of full AI to start. Premium follows later; the logbook stays free when it does.
Dex
Powerlifting · Tough love
Squat felt heavy again. Add weight anyway?
No. You've put 5 kg on it in three weeks and both sessions last week were RPE 9. Hold 100 kg one more week, then add. You'll get the bar speed back first, and the jump will stick.
Reads your training. Never your food logs.
Mira
Sustainable fat loss · Calm mentor
You're 22 g under on protein with dinner still to come — nothing dramatic, just worth knowing. The Greek yoghurt you logged Tuesday would close most of it.
Reads your food. Never your training logs.
They pass each other a short summary: your goal, your rough load, how recovery is going. Never each other's raw logs.
Two sides, not two apps
So Xoof gives each its own home, its own colour and its own coach. Run one side and you will never see the other. Run both and each knows roughly what the other is doing.
Training
Lime sideLog a session once and it does five jobs: your history, your records, your volume chart, your next plan, and the evidence your coach argues from.
Nutrition
Tangerine sideA calorie total tells you very little on its own. Xoof tracks protein, fibre, food variety and how processed the day was alongside it, and never turns any of that into a verdict on you.
Capture without the chore
Every method lands in the same place: an editable draft you check before it saves. Xoof never writes a record you have not seen.
For training
Talk through it on the walk out. "Bench, five at eighty, then three sets of eight."
Paste a plan or thumb a line between sets. Same parser, no microphone needed.
The full editor is always there — sets, reps, load, RPE, supersets, notes.
For nutrition
Get back an editable draft with ingredients, portions and macros to correct.
Real product data. If it is missing, add it once and it is there next time.
Saved meals, recent meals and your food library make repeat breakfasts a tap.
Logging works offline too — captures queue up and sync when you are back on signal. On the gym floor that matters more than it sounds.
The journey layer
Set a body-weight or strength target and Xoof works out where you started, how fast you are actually moving, and when you are likely to arrive. All of it is calculated from your own logs, with no AI anywhere near the number.
An arrival range, never a promised date
Body weight moves in a jagged line, so one confident date would claim more than the data supports. Xoof shows the window your current pace covers.
Falling behind never speeds you up
The pace is capped once, when you set the goal. Missing it never makes Xoof demand a steeper deficit to catch up. That cap lives in the projection code, so no change of wording can quietly undo it.
Losing faster than planned raises a flag
If a cut is running ahead of the rate you chose, Xoof says so and asks about it. It will not applaud a rate it would have refused to set.

Read off your trend so far, and it moves as you keep logging.
Calculated inside Xoof from weigh-ins you logged. No AI call, no credits spent.
Where the AI stops
Every figure Xoof shows you comes out of a function you could check by hand. The model is handed those figures and writes about them. It is never asked to work one out.
These come from deterministic functions over your own logs. Same input, same output, every time. No AI call, no credit cost.
The coaches interpret and explain. They are handed the figures rather than working them out, and they are instructed never to diagnose.
AI can be wrong. Every capture is yours to correct before it saves, and coaching is general information — never medical advice.
Worked example
Yesterday's food quality, broken into named components, with the actual foods that moved each one listed underneath. If you disagree with the score you can see exactly which plate to blame. A day you barely logged gets no score at all, because a missing label says nothing about the meal.
It scores the composition of the food and nothing else: not your calories, not your adherence, not you.

Your data
There is no advertising business behind Xoof and no plan for one. Charging for Premium later is how we intend to keep it that way.
Never sold
Your data is never sold, and never shared with advertisers or data brokers.
Never trained on
Your workouts, meals, notes and conversations are not used to train any AI model.
AI is opt-in
Health-adjacent data goes to AI only on your explicit consent, which you can withdraw any time. Manual logging never needs it.
Yours to take back
Export everything as JSON, or delete your account permanently, from inside the app.
There is no cookie banner because there is nothing to consent to — no advertising or third-party tracking cookies at all. See how we handle your data.
Almost there
Xoof is in testing on Google Play now. When it goes public you can start logging without handing over a card, and spend 14 days on full AI to find out whether two coaches change anything for you.
What it costs
While Xoof is in testing: no subscription, no in-app purchase, no card field to fill in.
Free today
Premium follows once testing ends
Premium is what will fund the AI after your 14 days run out. The logbook stays free when it lands, and we will publish the price here before anyone can be charged. What that means.
Questions
Two separate specialist coaches. Your training coach only ever sees your training, and your nutrition coach only ever sees your food — they exchange a short summary, never each other's raw logs. You choose each coach's focus (what they coach) and their delivery (how they talk) independently, so you can have a blunt powerlifting coach and a calm, low-pressure nutrition coach at the same time.
Training: speak a session, type it, or use the manual editor. Nutrition: photograph the plate, speak it, type it, scan a barcode, or reuse a saved meal. Every AI capture comes back as an editable draft that you review before anything is saved — Xoof never writes a log you have not seen.
No. Personal records, training volume, goal pace, arrival estimates and the daily food-quality score are all calculated deterministically inside Xoof from data you logged. They involve no AI call and cost no credits. The AI writes coaching on top of those numbers; it does not invent them.
The Android app is the first release and it is on a Google Play testing track now, which is the last step before it goes public. There is no download link yet; when there is, it will be on this site. Ask us on the Get Xoof page and we will send you one email on the day it goes live.
Nothing today. Xoof takes no payments while it is in testing: no card, no subscription, no in-app purchase, nothing to cancel. Once testing finishes we will introduce a paid tier, Xoof Premium, because the AI has a real running cost behind it and we would rather charge for it than sell your data. The logbook stays free when that happens — logging, history, records, libraries, targets and goals are not going behind the paywall. Premium is what keeps the AI going once your 14-day allowance runs out. We will publish the price here before anyone can be charged, and moving to Premium will always be a choice you make.
The whole logbook on both sides, free and not time-limited: workout and meal logging, full history, personal records, the exercise and food libraries, saved meals, templates, targets, goals and the rest timer. New accounts also get 14 days of full AI: voice, photo, both coaches and plan generation, with no card, because there is no card field to fill in. After those 14 days the AI pauses and the logbook carries on unchanged. Premium is what will restart the AI.
We never sell your personal data, never share it with advertisers or data brokers, and never use it to train any AI model. AI features run on your explicit consent, which you can withdraw at any time without losing manual logging. You can export everything or delete your account permanently from inside the app.
No. Xoof is a logging and coaching tool, not a medical device or healthcare service, and it cannot diagnose, treat or prevent anything. Coaching is general information only. If you have an injury, a health condition, or a difficult relationship with food or your body, please speak to a qualified professional — see our Health & Safety Disclaimer.
