How it works
Add your medication and current dose once. Ondula works out your schedule, reminds you on dose day and keeps the rest of your week in view.
A countdown to your next shot or daily pill, a reminder on dose day at the time you choose, and a gentle follow-up if you haven’t logged it yet. Injection-site rotation shows where you went last time, so you don’t reuse the same spot.
A chart of how much medication is likely in your body, built from the doses you log and published pharmacokinetic averages. It’s an estimate to help you understand your week, not a lab result.
Appetite is often lower on GLP-1s, so many people aim for protein first. Snap a meal for an AI estimate of protein and calories you can adjust, and keep an eye on your daily protein and water goals.
Log your weight to see your trend toward your goal. Side effects are logged by day of your dose cycle, so it’s easier to notice when they tend to show up.
Export your doses, weights, side effects and meals as one CSV file and share it with your doctor.

Ondula applies a standard one-compartment pharmacokinetic model with first-order absorption to every dose you log, using published average half-life, absorption and bioavailability figures for your medication. The result estimates how much medication is in a typical body over time. Your actual levels can differ, and the chart is never used to suggest a dose.
Yes. Tracking, the level chart and dose reminders all run on your phone without a connection. Meal scanning needs the internet, because the photo is analysed on our server, and purchases go through the App Store or Google Play.
Yes, with Ondula Pro. Export your doses, weights, side effects and meals as a CSV file and send it however you like from your phone’s share sheet.
No. Ondula works without sign-up. Subscriptions are tied to your App Store or Google Play account, and an anonymous ID tells the app whether Ondula Pro is active.
Subscriptions are managed by Apple or Google. On iPhone, go to Settings → your name → Subscriptions. On Android, open Google Play → Payments & subscriptions → Subscriptions. Cancel at least 24 hours before the current period ends to avoid renewal. Deleting the app doesn’t cancel your subscription.
Add your medication once and let Ondula keep track of the week.
