Reverra is the on-device companion for the people who are done with passive monitors. We build the daily charter, coach the meals, scan the labs, and pair with the meters you already own — all without your numbers ever leaving your phone.

vs FreeStyle Libre & passive monitors
Libre tells you. Reverra teaches you.
CGMs are extraordinary at measurement and almost silent on intervention. Reverra picks up where the sensor stops — pairing your numbers with the daily decisions that move them.
CGMs & passive trackers
A graph of your problem. Updated every minute.
Tells you a number went up — never why or what to change.
Disposable sensor every 14 days. The bill never stops.
Your data lives on their cloud, on their terms.
No meals. No movement. No habits. Just curves.
Reverra
A daily plan that uses your numbers — without owning them.
A charter every morning — meals, movement, habits — tuned to today's labs.
Pairs with any Bluetooth meter, BP cuff, or scale you already own.
Data lives on your device. Nothing leaves without your tap.
Scan a meal — get carbs. Scan a lab — apply to your profile.
What's inside
Less data entry. More reset.
Six tools, one quiet promise: the work happens with you, on your phone, on your terms.
🌿
The daily charter
Each morning, Reverra writes today's plan: 5 meals with carbs & protein, 3 movement blocks, 3 habits — tuned to your last 30 days of logs.
Adapts daily

Vision AI
🧪
Scan your labs
Photograph a lab report. Reverra reads A1c, lipids, glucose — converts units automatically, applies values to your profile with one tap.
OCR · units-aware
📟
Pair the meters you already own
Bluetooth glucose meters, blood-pressure cuffs, smart scales, heart-rate bands — Reverra reads them via the standard medical profiles. No proprietary lock-in. No new hardware to buy.
Web Bluetooth · BLE standard

Reverra, your coach
A warm, rigorous chat that knows your data and answers in your context. Cravings, readings, plateaus — ask anything.
Your AI key · your choice
How it works
Three honest steps.
No funnels, no upsells, no waiting list. Open it, set it up, start.
i.
Tell Reverra about you
Five short questions — age, weight, last A1c, diet style, your one goal. Two minutes. Nothing more than your doctor asks.
ii.
Set your tools
Bring your own AI key (Claude, OpenAI, Gemini, or free Groq). Pair the Bluetooth meter on your shelf. We don't sell hardware.
iii.
Follow the charter
Open the app each morning. Check off meals. Walk after eating. Log a reading. Watch the line bend.

FAQ
Honest answers to real questions.
No. Reverra is an educational and coaching tool. It does not diagnose, treat, or replace any medical care. Always coordinate medication changes — including for type-2 diabetes — with your doctor.
CGMs route your readings through their cloud by default. Reverra writes everything to your phone's local database. Every time data leaves your device (e.g. to ask the AI coach a question), Reverra shows what's being sent and asks for your tap. You can read the ledger of every transmission at any time.
Any device that implements the standard BLE profiles: Glucose Profile 0x1808, Blood Pressure 0x1810, Weight Scale 0x181D, Heart Rate 0x180D. That covers most Contour, OneTouch, Accu-Chek, Omron, Withings, and Eufy devices. Web Bluetooth runs on Chrome, Edge, Opera, and Samsung Internet on Android & desktop. (iOS does not yet expose Web Bluetooth — we're tracking this.)
It keeps Reverra free and keeps you in control. You pay the provider directly (often pennies a month), the key lives on your device, and Reverra never sees it. Or pick free options like Groq. If keys aren't your thing, the Patron tier bundles credits.
Within reason. It's the same vision capability that powers modern AI assistants — accurate for clearly visible meals, less so for liquids in opaque containers or unfamiliar regional dishes. We surface its confidence and the estimate is yours to accept or adjust before logging.
Yes. Auth is optional. Passkeys give you device-bound protection without a password, and an optional 6-digit code (TOTP) adds a second factor for sensitive actions. None of these talk to a server — the cryptography happens entirely on your phone.

Two minutes to set up. Free forever. Your data, your device, your terms.
Your data lives on this device. Sign-in is just a way to lock it down — we never see your credentials.
or use a display identity
or
A note about social sign-in: Reverra has no backend, so we cannot perform a real OAuth handshake with Google or Apple. Choosing one of those options simply sets a display name — your provider is never contacted, no tokens are exchanged, and nothing about you is sent to them. Passkey is the cryptographically real option here.
Reverra is not a medical device. By continuing, you agree it is educational and does not replace clinical care.
