the fitness app
that shows
its work.
most apps inflate your numbers to keep you happy. we calculate the real ones. then we cite the peer-reviewed study behind every single number.

why pay $400+ a year?
to cover all your health pillars - nutrition, training, weight, habits, and sleep - you're forced into seven separate subscriptions. seven apps that can't talk to each other, charging you over $400 a year for fragmented data silos.
7 apps · 7 bills · 0 shared data
food database only. ads, no calorie math, no coach.
detailed micros, but tedious entry and complex ui.
photo logging only. no training, no evidence layer.
clean workout logger. zero nutrition or weight sync.
weight tracking only. generic math, popups, no citations.
gamified habit tracking. no health data, no fitness sync.
sleep tracking only. no nutrition or training context.
evidence-based science.
tappd in puts calorie math, food logging, training, sleep, hydration, and coaching into one place. every pillar talks to the others. one subscription, the whole stack.
get the number right first.
real maintenance, no guesses
most apps guess your maintenance calories using generic activity multipliers. get this number wrong, and every deficit, surplus, and macro calculation on top of it is wrong. we calculate it accurately based on your actual lifestyle, steps, and activity. by working with your true maintenance instead of generic guesses, you will reach your goals faster and healthier.
snap your plate. get the macros.
take a photo of any dish. the app reads what is on the plate, gives you editable weights and portions, and lets you adjust before anything gets logged. nothing is automatic.
roasted means oil. we flag it and make you log it separately. olive oil, ghee, butter. the hidden calories nobody else counts. we do.
* template estimate. confirm and adjust weights before logging.
four ways in.
none of them annoying.
ai photo scan
snap your plate. the app reads the dish, gives you editable weights, and asks about oil if it was cooked.
snap and confirm. nothing auto-logged.barcode scan
point at any packaged product. it reads the label and pulls up the macros instantly.
over 1.4 million productsmanual search
search from desi staples, whole foods, and packaged brands. your 30 most recent foods are one tap away.
your history pre-loadedlog from chat
tell the coach what you ate. it understands, confirms the weights, and logs it without switching screens.
just describe it in plain englishbuilt around your week, not a template.
tell us how many days you can train, how long each session, what equipment you have, your experience level, and how hard you want to push. we generate a split with volume targets backed by research, and every exercise carries a rationale.
log every set. the data does the rest.
your generated plan becomes your active session. log weight, reps, and reps-in-reserve for every set. personal records track themselves. close the app mid-session and your progress is still there when you come back.
your recovery, finally in the equation.
nutrition and training only pay off if you recover. sync sleep straight from apple health, oura, whoop, or garmin - or log it by hand in two taps. we score the night, track your trend, and feed it back into your calories and training load. now it's the full stack: fuel, train, recover.
hydration is more than ounces.
tap a glass, log 300ml - the fastest way to stay on top of water. but real hydration is electrolytes too. we track sodium, potassium, and magnesium against targets scaled to your sweat, training, and climate, so you actually absorb the water instead of just drinking it.
science-backed coaching
the coach knows your numbers. your calories today, your last workout, how your training volume is stacking up, what you ate. it answers from that context, not from a generic playbook. every response cites a study. no bro science, no invented claims. and now you can just talk to it - ask out loud mid-workout and hear the answer back.
close four rings. keep the streak.
one ring per pillar - nutrition, hydration, sleep, and training. hit all four targets in a day and the day counts. miss one and the ring stays open. no vanity metrics, no participation trophies: the streak only moves when you do the work across every pillar.
tap why.
read the paper.
everywhere the app gives you a number or tells you to do something, there is a yellow why? chip. tap it. you get the study in plain english, the confidence level, and a link straight to the real paper.
1.6 to 2.4g per kg of bodyweight maximises muscle growth. past this range, extra protein has no measurable benefit.
a citation behind every number.
tap any calorie target, macro split, or training recommendation in the app. a card opens with the claim in plain english, a confidence rating, and a link to the actual study. open it. read it. verify us.
1.6 to 2.4g of protein per kg is all you need to maximise muscle growth. past that, the extra does nearly nothing.
a 300 to 500 kcal deficit loses fat at a sustainable rate without the muscle loss or metabolic adaptation that crash diets cause.
10 to 20 sets per muscle per week is the evidence-based sweet spot for hypertrophy. under 10 you leave gains on the table.
daily movement outside the gym can vary calorie burn by up to 2,000 kcal between two people of the same size. most apps ignore this.
every card in the app carries a real doi. tap it and the paper opens. we show our work.
