Most health products store records. StatsKey builds a private operating model of you: meals, micronutrients, CGM, activity, sleep, hydration, symptoms, training, and the decisions that connect them.
The connected model
One model of you — not a dozen disconnected apps.
Fast capture at the edge, structured records underneath, and a clean interface for the patterns that matter.
Connect the signals.
Meals, glucose, workouts, sleep, recovery, hydration, GI health, and mood live in one model — synced from Apple Health and your Apple Watch.
Make it clinical when needed.
Generate nutrition, CGM, training, and GI reports built from real records instead of averages — exportable across any date range.
Adapt targets over time.
Metabolic targets can move with Apple Health activity, training load, and recent intake behavior — not a fixed number you set once.
Exercise recording
Track runs, walks, rides, swims, hikes, trail runs, mountain and road cycling, rowing, elliptical, stair stepper, yoga, pilates, strength, HIIT, CrossFit, basketball, soccer, tennis, golf, volleyball, skiing, snowboarding, surfing, skateboarding, paddleboarding, kayaking, climbing, dance, martial arts, boxing, and other workouts. GPS sessions can include route maps, distance, moving time, pace, speed, elevation, calories, heart-rate samples and zones, cadence, splits, segments, weather, perceived effort, notes, and photos. Trends & Averages roll your run history up over any period — a week, a month, a year, or all time — and best efforts from the mile to the marathon are graded for your age and sex, with every session synced from Apple Health and your Apple Watch.
Where StatsKey sits
Accurate or effortless. StatsKey is the rare both.
Verified trackers are rigorous but slow and leave most micronutrients blank. Effortless photo apps are fast but shallow. StatsKey is the missing middle — low-friction capture, per-nutrient provenance, deficit detection, and a connected model neither side has.
The live app — macros, glucose response, the full nutrient panel with deficit flags, and Intelligence insights. Actual screen recording.

Record, with provenance
We store a number — and how it was known.
Every food record carries a three-axis trust model, so your data stays legible — not just present.
Identity
What the food is — barcode match, official label, visual recognition, or grounded search.
Nutrients
Where each value came from — barcode database, the official label, USDA-grounded data, or an Intelligence estimate, each with its own confidence.
Quantity
How sure we are of the amount you ate — user-adjusted, an assumed serving, or a visual estimate.
Grounded in USDA FoodData Central. For branded items StatsKey never fabricates a label — if it can't be verified, it returns nothing. Intelligence estimates are flagged and reversible.
Record by photo, barcode, label, or text — and watch it resolve into a full, sourced Nutrition Facts panel. Actual screen recording.
See what's missing
Most of us are short on something. Few apps can tell.
StatsKey grades your intake against reference levels and flags likely shortfalls across the nutrients that populate on a typical day — the gaps nutrition science has named for decades and most trackers still leave blank.
Vitamin D~94%of US adults below the requirement
Potassium~100%under the adequate intake
Magnesium~52%below the requirement
Calcium~44%below the requirement
NHANES 2007–2010 / 2003–2018 (Linus Pauling Institute; 2020 DGAC shortfall nutrients) — even counting supplements.
The full vitamin & mineral panel — not just the four or five most apps surface.
Measure your response
The same meal — your actual response.
Connect a CGM and StatsKey reads each meal's real effect on you: incremental area under the curve, peak, and recovery, plus second-meal effects — from Dexcom, Libre, or Nightscout. Personal context, not a headline number.
A metabolic day, and food ⇄ glucose analysis Intelligence can read back to you. Actual screen recording.

Illustrative interaction. In the app, these are computed from your own CGM for every recorded meal — iAUC, peak, recovery, dips, and second-meal effects.
Ask your own data
From diary to decision system.
Intelligence reads your connected record — meals, micronutrients, glucose, training, sleep, and wellness — and answers in plain language, grounded in your own data and remembered across sessions. Not generic averages.

Intelligence insight ready
Higher potassium days are tracking with better morning energy.
It cites its work — or says it doesn't know.
Answers stay grounded in your own records, cite their methods, and refuse to invent numbers or percentiles. Deeper analysis and Deep Dives run on metered Intelligence tokens from the Store.
Why did my glucose crash overnight last Tuesday?
Your dinner at 8:47 PM had 94g carbs with only 12g fat. Meals above 80g carbs with under 20g fat correlate with overnight drops below 60 mg/dL 83% of the time in your recent records.
Adaptive Intelligence. Targets that keep themselves honest.
Set a goal and StatsKey maintains the math: a formula ensemble tuned to your body, thirty days of Apple Watch activity, and your gap-aware weight trend, reconciled into one maintenance number. When measured reality disagrees with the formula, reality wins — in proportion to the evidence.
Confidence gates the correction: Baseline (formula) → Medium (+ Watch) → High (+ weight trend). Manual edits always win — flip one switch and it's your number again.

High confidence — cross-validated by your weight trend
It already knows your data.
Today's totals, recent workouts, glucose, and wellness are in context on every question — and it keeps a running set of notes about you, so it doesn't start cold each session.
Pick the model.
Claude Sonnet or Opus on the web, plus managed Gemini, OpenAI, and Grok routes in the app — no API key to manage, metered by Intelligence tokens.
Insight on any meal.
Tap Insight for a per-food read and a one-line summary in the style you set — detail level, emphasis, even your own instructions. It runs only when you ask, never automatically.
Point it at everything.
Deep Dive reads your timeline month by month, then synthesizes what actually changed. One report, grounded in all of it.
The hardest signal to talk about
The gut: huge, multifactorial, and mostly invisible.
Around 40% of people have a disorder of gut–brain interaction and ~12% have IBS; most name food as a trigger, but every trigger list is individual. In one US study, more than 60% of patients hid bowel-urgency symptoms from their own doctor out of embarrassment.
StatsKey records bowel movements on the Bristol scale right alongside food, fiber, glucose, and training — a judgment-free record you can simply ask Intelligence about. No one has to say a word.
NIDDK (IBS ~12%) · Rome IV DGBI epidemiology (Sperber 2021; Palsson 2020) · Lilly CONFIDE (bowel-urgency underreporting).
Bristol-scale bowel movements, symptoms, mood & energy — recorded in seconds, private by default.
Momentum
Built so you actually keep recording.
Recording compounds. StatsKey turns a week of data into something you want to come back to — and rewards the habit instead of punishing a slip.
This Week in StatsKey.
Finish a recording week and unlock a shareable recap that names your athlete type from your real data. Add your age and sex and your VO₂max and protein show up as a national percentile.
Streaks that forgive a slip.
Build a recording streak and earn streak freezes as you go. Miss a day and a freeze is used automatically instead of resetting you to zero — and the 7-Day Challenge earns a free month of Pro.
Better with friends.
Invite a friend and you both get a free month of Pro. Compare activity, share what you choose with granular privacy controls, and view your own record exactly the way friends see it.
Where it's headed
From estimated intake to measured biology — and back.
Recording and deficit detection estimate what your body is likely missing. The roadmap closes the loop: confirm it with real labs, read the results against how you actually live, then change one thing and re-measure.
Flag likely shortfalls.
Recording plus deficit detection surface probable gaps — vitamin D, fiber, magnesium — from food alone, today.
Confirm with real labs.
On the roadmap: at-home blood & stool panels through a CLIA/CAP partner lab confirm what intake can only estimate.
Against how you live.
Labs interpreted against your nutrition, glucose, training, and sleep history — not isolated numbers on a portal.
Change one thing, retest.
A personal, longitudinal feedback loop on your actual body — estimate, measure, correct, re-measure.
Wellness, not a medical device
StatsKey is a wellness and self-tracking tool — it doesn't diagnose or treat, and the lab features above are on the roadmap, delivered through partner labs within the wellness boundary. Intelligence estimates are approximate by design.
