Your GLP-1 journey, private and simple OffGrid Dose is the privacy-first tracker built for people on semaglutide, tirzepatide, Ozempic, Wegovy, Mounjaro, Zepbound and other GLP-1 medications. No accounts. No servers. Your weight, doses, photos, and side effects stay on your device, where they belong. --Why OffGrid Dose-- Most weight and medication trackers send your data to a cloud server, ask you to create an account, and monetize your behavior. OffGrid Dose does none of that. There is no backend. There is nothing to hack, subpoena, or sell. Your device is your record. --Built for the weekly injection-- • 10-second check-in flow Log your dose, injection site, and weight faster than it takes to uncap the pen. • Injection site rotation map Track eight zones across the abdomen, thigh, arm, and hip, with “last used” memory so you never double up. • Medication level curve See an estimated concentration curve between doses, computed locally using published half-life and t-max data. • Titration-aware dose graphs Includes presets for Ozempic, Wegovy, Mounjaro, Zepbound, and compounded semaglutide/tirzepatide. --Progress that tells a story-- • Weight chart with dose-change markers • Total change, weekly average, BMI, percent change, current weight, and distance to goal • Progress photos from front, left, and right angles, stored only on your device • Before/after comparison image you can share, only if you choose --Side effect tracking-- • Quick-tap logging for nausea, fatigue, GI symptoms, headaches, hair thinning, injection site reactions, and more • Severity and resolution tracking • Correlation view to help spot patterns around dose changes --Daily calendar & notes-- • Month grid with per-day indicators for weights, injections, and symptoms • Free-form daily notes for context your future self will thank you for --Local reminders-- • Weekly injection reminder on the day and time you choose • Optional daily weight reminder • All notifications are scheduled on-device and are never sent through a server --PDF export for your doctor-- Generate a clean, printable summary of your weight history, dose changes, injection log, side effects, and notes for any date range. --Privacy, guaranteed by architecture-- • No account creation • No database servers to get hacked • All the data user enters on the app is saved only locally on their device --Subscription-- Subscriptions auto-renew until canceled and can be managed anytime in: Settings → Apple ID → Subscriptions Prices are shown on the subscription screen inside the app and are charged to your Apple ID at purchase confirmation. Your subscription automatically renews unless turned off at least 24 hours before the end of the current period.

Taking a GLP-1 medication is a big step. Whether you just started Ozempic, switched to Mounjaro, picked up Foundayo, or you're a year into your journey with Wegovy, you deserve a tracker as thoughtful about your experience as you are about your health. Lumis was built for the way GLP-1 treatment actually works — not just weekly injections, but daily pills, combination regimens, dose changes, and the day you decide you're ready to stop. It's the tracker that doesn't lose your data, doesn't surprise you with charges, and doesn't treat your progress like an afterthought. TRACK YOUR WAY Log injections or oral doses with the medication names you actually use — including compounded medications and peptide stacks. Track multiple medications at once, see where your last injections were on a body map, and keep a complete history you can scroll through anytime. Your weight, your story. Log today's weigh-in or backfill the last few months. See how your weight changed relative to your dose schedule, spot trends across weeks and months, and set a goal weight that keeps you motivated without pressure. Track how you're feeling, not just what you're taking. Log multiple symptoms per day with notes, then see patterns emerge — like how your nausea changes across dose adjustments. BUILT FOR YOUR WHOLE JOURNEY A GLP-1 journey rarely follows a straight line. You might reach maintenance, stay there for years, return to active loss, taper again. Most trackers assume you'll either stay on the medication forever or drift away once you reach goal. Lumis assumes neither. Maintenance mode is a fully designed phase — not an exit. Track the habits that matter most (protein, exercise, daily weigh-ins), set your own weight alerts on your terms, and keep the structure that worked. When your journey shifts again, switch back to active tracking the same way you switched in — same support, either direction. THREE DAILY GOALS — PROTEIN, HYDRATION, STEPS GLP-1 medications can make it hard to eat enough protein — and protein matters for preserving muscle during weight loss. Lumis makes it simple: log grams per meal, set a daily target, and see at a glance whether you hit it. Track hydration the same way, and let Apple Health surface your daily steps so the picture stays complete. No complicated food databases, no unreliable AI photo scanners — just the numbers that matter most. YOUR DATA, YOUR DEVICE Lumis stores your health data on your device, with optional iCloud sync between your own devices. Most trackers send anonymized health data to analytics services to understand product trends — Lumis does not. There is no third-party SDK in the app, no analytics, no telemetry. Crash data comes through Apple's privacy-protective channel only, and you can turn it off. We never see your data because the architecture makes seeing it impossible. Export your data anytime — it's your health history, and you should always be able to take it with you. HONEST PRICING Lumis is free to download with daily tracking included — doses, weight, symptoms, protein, hydration, steps, day notes, phase switching, and Apple Health sync. Premium adds cross-device iCloud sync, dose reminders, advanced maintenance tooling, and richer charts and symptom patterns — for $19.99 per year. No ads. No trials that secretly charge you. No price that doubles overnight. If you upgrade, it's because you chose to, not because you forgot to cancel. DESIGNED FOR iOS 26 Built natively for iOS 26 with SwiftUI and liquid glass — made for iPhone, not ported to it. — Lumis is not medical advice. It does not provide dosing recommendations, interpret your symptoms, or suggest medication changes. Always consult your healthcare provider about your GLP-1 treatment. Semaglutide, tirzepatide, orforglipron, liraglutide, dulaglutide, and exenatide are active ingredients in prescription medications. Lumis is not affiliated with or endorsed by any pharmaceutical manufacturer.
