RedoseIf you have been searching for a Shotsy alternative, you are likely looking for more flexibility: broader medication support, deeper tracking features, or an app that works on both iPhone and Android. Redose is worth a look. It covers GLP-1 shot logging from day one and extends to research peptides, built-in calculators, injection-site body mapping, calorie and food logging, macro and water tracking, and a full adherence dashboard, all in one free-to-start app.
What Shotsy does well
Shotsy has earned a following among people starting GLP-1 medications. It offers a focused, low-friction experience for logging injection shots, and many users appreciate how quickly they can record a dose without navigating a complex interface. For someone whose only goal is to note that they took their weekly semaglutide or tirzepatide shot, Shotsy delivers a clean, purpose-built experience with a low learning curve.
Where Redose is different
Redose was designed from the start to handle a wider range of injectable protocols and to cover the nutrition side of a GLP-1 program, not just the injection side. That breadth shows up in several concrete ways:
GLP-1 plus research peptides. Redose tracks semaglutide, tirzepatide, liraglutide, and compounded formulations alongside research peptides like BPC-157 and TB-500. If your protocol involves more than one injectable, everything lives in the same app with the same logging workflow.
Calorie, food, and macro tracking. Many people on GLP-1 medications are also actively managing what they eat. Redose includes a full food and calorie log so you can track meals, macros (protein, carbs, fat), and daily calorie totals in the same app where you record your injections. You do not need a separate nutrition app.
Water tracking. Hydration matters especially on GLP-1 protocols where appetite suppression can reduce fluid intake. Redose includes a daily water log with a progress indicator so you can hit your hydration goal alongside your dose and nutrition goals.
Injection-site body map. Every dose log lets you tap a body-map illustration to record exactly where you injected, abdomen zones, thighs, upper arms, and more. The app surfaces your rotation history so you never have to guess which side you used last time.
Built-in calculators. The reconstitution and dose calculators handle the arithmetic that trips up new users: how much BAC water to add to a lyophilized vial, what volume to draw for a given dose, and how to convert between mg, mcg, and syringe units. These live in the app and require no account.
Live vial and pen inventory. Redose tracks how many doses remain in each vial or pen and sends a reorder reminder before you run out. It also estimates how long your current supply will last based on your scheduled protocol.
Offline-first and cross-platform. All data writes to your device first. The app works without a network connection and syncs silently when connectivity returns. Native apps for iPhone and Android share the same data model, so your logs are consistent regardless of which device you reach for.
Weight, food, and health sync. Redose integrates with Apple Health (iPhone) and Health Connect (Android) to pull in weight, steps, and other metrics alongside your injection history, giving you one timeline to review with your care team.
Doctor-ready PDF export. A single tap generates a formatted report covering dose history, injection sites, symptom notes, and weight trends, formatted for a clinical conversation rather than a screenshot.

Who should choose which
Choose Shotsy if you are tracking a single GLP-1 medication and want the simplest possible shot-logging experience with minimal setup. Shotsy is purpose-built for that use case and has a community of GLP-1 users already.
Choose Redose if you:
- Want to track GLP-1 medications and research peptides in the same app without juggling separate tools.
- Also want to log calories, food, and macros so you have one app for both the medication side and the nutrition side of your protocol.
- Need injection-site rotation guidance with a visual body map.
- Do the math on reconstitution or unit conversion and want a calculator built into the app rather than a separate spreadsheet.
- Use both iPhone and Android across your household or want to switch platforms later.
- Want your dose history, weight, nutrition, and symptoms in one exportable report you can hand to your prescriber.
- Prefer an offline-first app where your data stays on your device by default.
Both apps aim to reduce the friction of injectable therapy. The right choice depends on how much of your protocol you want one app to cover. If you are only logging a weekly pen injection, either will serve you well. If you are managing a multi-compound protocol, tracking vial inventory, running reconstitution calculations, or logging food and calories alongside your doses, Redose is built for that depth.
