Redose
If you are using a GLP-1 medication, an investigational peptide, or any other injection-based protocol to support weight loss, Redose is the weight loss tracker app built specifically for that routine. Available on iPhone and Android, it brings dose logging, weight trends, injection site rotation, and side-effect journaling into one place so your progress is always visible and your data is always ready to share with a clinician. Redose also logs calories, food, macros, and water alongside your doses, so you do not need a separate calorie app running next to it.
What Is a Weight Loss Tracker App
A weight loss tracker app does more than graph body weight on a line chart. For people using injectable medications or peptides, the meaningful picture includes what was injected, how much, where on the body, and what symptoms or changes followed. That context is what turns a series of numbers into actionable information.
Typical challenges people run into without a dedicated tracker:
- Losing track of the injection schedule. Weekly or bi-weekly intervals are easy to blur, especially across titration steps.
- Not knowing which site was used last. Rotating through the abdomen, thigh, and upper arm matters for absorption and skin health.
- Running low on supply mid-cycle. A surprise shortage means a gap in treatment.
- Nothing to show the prescriber. A log that lives in your memory is not useful at a telehealth visit.
A purpose-built weight loss tracker app removes each of those friction points.
How Redose Does It
One-Tap Dose Logging
Tap Log Dose and Redose pre-fills the expected amount from your protocol. Confirm, and the timestamp, dose, and injection site are saved in under five seconds. Everything is stored offline first so the app works with or without a connection.
Weight Trend Charts Linked to Your Doses
Log weight manually or let Redose pull it automatically from Apple Health (iPhone) or Google Health Connect (Android). The trend chart overlays your dose history so you can see how each titration step corresponded to changes in weight, appetite, or energy over time.
Body-Map Injection Site Rotation
An interactive body diagram lets you tap the exact spot used for each injection. Redose tracks your rotation history and highlights recently used sites, making it straightforward to follow the spread-it-around practice most clinicians recommend.
Live Vial and Pen Inventory
Add a pen or vial once with its total volume and per-dose draw. Redose tracks remaining units in real time and sends a reorder reminder before you run short. No more guessing by tilting a vial toward the light.
Reconstitution and Dose Calculators
Working with a compounded or lyophilized peptide? The built-in calculators compute concentration, draw volume in both units and mL, and total doses per vial from any combination of vial size and BAC water. The same calculators are available free on the web.
Symptom and Side Effect Journal
Log nausea, appetite changes, fatigue, injection site reactions, or any custom note right from the dose screen. Pre-set one-tap buttons cover the most commonly reported side effects so journaling takes seconds rather than minutes.
Adherence Dashboard
A weekly and monthly calendar view shows every logged dose at a glance. Color-coded adherence percentages make it easy to see whether you are sticking to the intended schedule and how side effects have shifted across titration steps.
Doctor-Ready PDF Export
Generate a clean summary report covering dose history, injection sites, weight trend, and symptom notes. Bring it to an appointment instead of trying to reconstruct the last several weeks from memory.
Track Your Food and Water Too
On a GLP-1, appetite often drops significantly, which makes hitting protein targets and staying hydrated more important, not less. Redose lets you log meals, calories, and macros right inside the same app where you track your shots, so nothing lives in a separate tool. You can also log daily water intake and see how hydration holds up across your cycle. All of it trends together in one dashboard, making it easy to spot weeks where low protein or poor hydration lined up with slower progress or extra fatigue. For details on each feature, see the dedicated calorie tracker and water tracker pages.
Why It Matters for GLP-1 and Peptide Users
GLP-1 receptor agonists (semaglutide, tirzepatide, and related compounds) and other investigational peptides used to support weight management typically run on multi-week titration schedules. The window between a dose that is well tolerated and one that causes avoidable side effects is often narrow. Consistency and documentation are the two levers most within a user's control.
Consistency means hitting the right dose at the right interval and rotating sites correctly. Redose automates the reminders and the rotation log so both happen without extra effort.
Documentation means having real data when you talk to a prescriber. A Redose PDF export gives a clinician the full picture in under a minute, which is far more useful than a rough verbal summary.
For users tracking semaglutide-based protocols, see the dedicated Wegovy tracker. For tirzepatide, see the tirzepatide tracker. If you are managing multiple compounds, the full list of supported protocols is at /trackers.
FDA-approved GLP-1 medications are prescribed for specific indications. Many peptides in this category are still investigational and not approved for general use. Redose does not prescribe, recommend, or validate any protocol. It records what you take accurately so you and your care team have the information you need.
