Redose
Redose is a free GLP-1 shot tracker for iPhone and Android that logs every injection in one tap, tracks injection-site rotation on a body map, and shows your full dose history in a clear adherence dashboard. Redose also logs calories, food, macros, and water alongside your doses, so you do not need a separate calorie app. Whether you are using a GLP-1 receptor agonist for weight management or metabolic health, Redose keeps the record-keeping frictionless so you can focus on the protocol itself.
What is a GLP-1 shot tracker?
GLP-1 receptor agonists, including semaglutide-based medications (Ozempic, Wegovy) and tirzepatide-based medications (Mounjaro, Zepbound), are typically administered as subcutaneous injections on a weekly schedule, often with a titration phase where the dose steps up every few weeks. Keeping track of all of this manually is easy to get wrong: a missed log, a forgotten site, or uncertainty about whether last week's pen was a 0.5 mg or 1 mg dose.
A GLP-1 shot tracker solves that problem by giving you a single, permanent record of every injection: when it happened, what dose was used, and exactly where on your body it was given. That record becomes genuinely useful when you talk to your prescriber, notice a pattern in side effects, or want to confirm adherence before a follow-up appointment.
How Redose does it
Redose was built around the principle that logging a dose should take no longer than five seconds. Here is what the experience looks like in practice:
- One-tap dose logging. Open the app, tap the vial or pen for today, confirm the dose and site, done. The log is saved instantly, even without a network connection.
- Visual body-map injection-site rotation. A front-and-back body diagram lets you tap the exact spot used, whether that is the abdomen, thigh, or upper arm. Redose shows your recent rotation history so you always pick a fresh site, which matters because repeated injections in the same spot can cause tissue changes over time.
- Live pen and vial inventory. Enter your starting pen count or vial stock. Redose tracks how much is left and sends a reorder reminder before you run out, useful during titration when your dose per injection is still changing.
- Reconstitution and dose calculators. If you are using a compounded or injectable peptide that requires mixing, the free calculators at /calculators walk you through the math: BAC water volume, concentration per unit, and the exact volume to draw for any target dose. These tools are available at no cost.
- Side-effect and symptom journal. Log nausea, fatigue, appetite changes, or anything else in the same session as your injection. Over weeks, the trend charts show you whether a symptom correlates with dose increases or peaks at a consistent time post-injection.
- Weight, food, and Health app sync. Redose connects to Apple Health (iPhone) and Health Connect (Android) so your weight trend and food intake sit alongside your dose history, all in one view.
- Doctor-ready PDF export. Generate a clean clinical summary of your dose history, injection sites, symptoms, and weight trend to bring to any appointment, no screenshots or manual summaries required.
Track your food and water too
On a GLP-1, appetite drops significantly, which makes it easy to under-eat protein and forget to drink enough water. Both matter for preserving muscle and avoiding side effects like fatigue and constipation. Redose includes a built-in calorie and macro tracker so you can log meals and see your protein, carbs, and fat totals for the day, right next to your injection history. The water tracker lets you record each glass or bottle and shows a running daily total with a goal indicator. Because everything lives in one app, you can spot patterns you would miss with separate tools, for example, noticing that low protein days follow high-nausea injection days.
Why it matters for GLP-1 and peptide users
Adherence is the single biggest predictor of outcomes on any injectable protocol. Missing a dose by a day, injecting into the same lipohypertrophic spot repeatedly, or miscalculating a reconstituted dose can all affect how well the medication works. A tracker removes those failure points.
For GLP-1 users specifically, the weekly schedule sounds simple until week three of a titration when you cannot remember whether you already increased to the next dose tier. Or until you realize you have been using the same two-centimeter patch of abdomen for a month. Redose makes the right behavior the default behavior: the app tells you what is next, where to inject, and how much.
If you are also tracking a research peptide alongside a GLP-1 (a combination some users report to their prescribers for recovery or metabolic support), Redose handles multiple concurrent protocols in the same app. Note that most peptides outside of approved GLP-1 medications are investigational and not FDA-approved for human use. Logging them accurately, and sharing that log with a qualified provider, is important.
