Tatva is a root-cause metabolic health tracker. Snap a meal, see how it lands on your gut, liver, and blood sugar, and learn the one habit shaping your week — without spreadsheets, calorie counts, or guesswork.
See how it works
In Sanskrit, tatva (तत्त्व) is the root principle behind a thing — its true nature, stripped of noise.
That's what this app is. Not another calorie counter. Not a scoreboard. A way to see what is actually driving how you feel — your gut, your liver, your blood sugar — so you can change the one thing that matters instead of all the things that don't.
No food databases to scroll. No portion math. A photo and two taps are enough.
Our AI reads the photo and identifies each item — avocado toast, salmon bowl, dal-chawal, pasta plate — with realistic portion sizes and macros. Before you tap "Looks right", you already see how the meal scores for gut, liver, and sugar plus the carb/fibre/protein breakdown. It works like a food-label scanner for any plate.
Tatva scores each meal across the three systems that actually decide how you feel — and tells you, in plain English, why. No mystery numbers. No 73/100 nonsense.
Tatva predicts the blood-sugar range your meal is likely to push you into — based on your baseline, your condition, and what's actually on the plate. Compare it to your real reading later (finger-prick, CGM, glucometer) and Tatva gets sharper at calling your patterns.
Tatva tracks fibre balance, fermentation load, FODMAP-style triggers, and the trickier stuff most apps ignore — emulsifiers in packaged food, deep-fried oil reused too long, late-night eating that disrupts the microbiome.
Your liver handles fructose, alcohol, fried oils, and processed seed oils. Tatva watches the cumulative load across the day — not just one meal — and warns when you're stacking it.
Tatva predicts your post-meal spike before you eat, factors in your baseline, your conditions (diabetes, PCOS, prediabetes), and what would actually flatten the curve — protein order, walking, swapping the side.
Tatva tracks meals, blood sugar, blood pressure, weight, gut symptoms, sleep, steps and heart-rate from your Apple Watch / iPhone Health. Don't have a glucometer or BP cuff? Tatva infers your sugar and heart picture from your meals — you still get the coaching, no hardware required.
Manual readings if you have a meter — or inferred from meal carb/fibre ratios if you don't. Same coaching either way.
Log systolic / diastolic with a tap. Live ACC/AHA category badge as you type. Or skip the cuff and infer from your sodium & fibre patterns.
Manual log or auto-synced from Apple Health / Health Connect. Pre-filled with your profile weight so tweaking takes one tap.
Bloating, cramps, heartburn — log severity 1-5. Verdict ring drops the moment you log a symptom, and the AI cross-references with your last meal.
One screen logs everything in one tap. Choose mode per condition during onboarding — "I measure it" or "Infer from my meals". Change anytime in Profile.
Tap "Ask Tatva" anywhere in the app. Your personal coach — grounded in your meals, readings, symptoms, sleep, and conditions. Not a generic chatbot regurgitating internet advice.
Most trackers drown you in charts. Tatva does the opposite. Each Sunday at 9 AM, it studies your week and surfaces a single pattern plus a single swap — the one change with the highest leverage.
Tell us your conditions once. Every verdict, prediction and tip shifts accordingly. A pasta meal isn't the same for someone with PCOS as it is for someone with IBS.
Most metabolic apps make you a data clerk. Tatva turns the data into one clear next step.
| Tatva | Calorie-tracking apps | Glucose-only apps | |
|---|---|---|---|
| Root-cause focus (gut + liver + sugar) | ✓ | Calories only | Sugar only |
| Photo-first meal logging | ✓ AI verdict in seconds | Barcode + database search | Manual log |
| Personalized to your condition | ✓ PCOS, diabetes, IBS, NAFLD… | No | Limited |
| AI chat grounded in your data | ✓ Ask Tatva | No | No |
| CGM required | No — works without | N/A | Yes |
| Weekly pattern (one habit at a time) | ✓ | Charts only | Charts only |
| Apple Health & Health Connect sync | ✓ Steps, sleep, HR, weight | Partial | Partial |
Tatva reads your steps, sleep, heart rate, HRV, weight, and glucose (where available) — and folds them into your meal verdicts. Slept poorly? Today's threshold for sugar shifts. Walked 8,000 steps? Your dinner verdict gets a small grace.
Read-only. We never write to your health records. Revoke anytime from your phone's settings.
No. Tatva works on photos, finger-prick readings, or no readings at all. If you do have a CGM (Libre, Stelo, Dexcom), it makes the predictions sharper — but it's not required.
No. Tatva is a personal wellness tool. It helps you notice patterns. It does not diagnose, treat, or replace your doctor. For any medical decision, talk to a qualified clinician.
