RedosePeople searching for a MacroFactor alternative are often on a GLP-1 medication or injectable peptide protocol and have noticed that nutrition and macro coaching apps, however polished, were not designed with injections in mind. Redose approaches the problem from a broader angle: it was built specifically for injectable health protocols and also tracks calories, food, macros, and water, so you are not forced to run a separate nutrition app alongside your dose tracker. It connects to Apple Health and Health Connect so your dose history, weight, food intake, and symptoms all live in one place.
What MacroFactor does well
MacroFactor is a respected macro and nutrition coaching app. It applies an adaptive algorithm to weekly weigh-ins and food logs to estimate your actual calorie expenditure and adjust your targets over time. Users who want evidence-based nutrition guidance delivered through a clean interface and backed by a transparent coaching philosophy find it genuinely useful. Its food database and barcode scanner are optimized for quick, accurate logging, and the coaching philosophy is grounded in peer-reviewed nutrition science. If adaptive macro coaching is your primary concern, MacroFactor is a thoughtfully built product with a clear point of view.
Where Redose is different
Redose covers the full nutrition side, calories, food, macros, and water, and adds the injection and medication layer that nutrition apps were never designed to handle.
Calorie, food, macro, and water tracking built in. Redose logs food and meals, tracks your daily calorie and macro intake, and records water consumption. If you are on a GLP-1 medication and monitoring your appetite changes alongside your dose schedule, you can see both in the same timeline without switching apps.
One-tap dose logging for any injectable. Whether you are tracking a weekly GLP-1 pen, a daily peptide injection, or a multi-compound research protocol, you log each dose in a single tap. The entry captures the compound, dose amount, timestamp, and any notes, all pre-filled from your saved protocol so there is nothing to type.
Injection-site body map and rotation history. Every dose log lets you tap a body-map illustration to record exactly where you injected. Abdomen zones, thighs, upper arms, and more are all selectable. Redose tracks your rotation history so you can see at a glance which sites you have used recently and avoid overusing one area, a detail that nutrition apps have no reason to know about.
Reconstitution and dose calculators. The calculators at /calculators solve the arithmetic that trips up people new to lyophilized peptides: how much BAC water to add to a vial, what concentration that produces, and what volume to draw for a target dose. A syringe units converter handles mg, mcg, IU, and units in one step. These tools require no account and live inside the app.
Live vial and pen inventory. Redose tracks remaining doses in each vial or pen and sends a reorder reminder before you run out. It estimates how long your current supply will last based on your scheduled protocol, which is especially useful for compounded medications with limited availability.
GLP-1 medications and research peptides in one app. Redose handles semaglutide, tirzepatide, liraglutide, and compounded formulations alongside research peptides like BPC-157 and TB-500. If your protocol involves more than one injectable compound, you do not need separate apps or spreadsheets.
Health sync with Apple Health and Health Connect. Redose integrates with Apple Health (iPhone) and Health Connect (Android) to pull in and push weight, steps, and other metrics. Your food intake, water, doses, and body metrics all connect through the health platform.
Doctor-ready PDF export. One tap produces a formatted report covering your dose history, injection sites, symptom journal, and weight trends in a layout designed for a clinical conversation.

Who should choose which
Choose MacroFactor if your primary goal is optimizing nutrition through an adaptive algorithm that adjusts your macro targets based on measured outcomes, and food logging is the center of your health routine. MacroFactor is a focused, well-regarded tool for exactly that purpose.
Choose Redose if you:
- Are on a GLP-1 medication or any injectable protocol and need a proper dose log with injection-site tracking.
- Want calorie, food, macro, and water tracking in the same app as your dose log.
- Want reconstitution or unit-conversion calculators built into the same app you use to log doses.
- Are managing a research peptide stack and need on/off cycle scheduling, vial inventory, and rotation history.
- Use both iPhone and Android and need your data on either device without losing features.
- Want to hand your prescriber a clean PDF report of your injection history, symptoms, and weight trends.
- Prefer an offline-first app where your health data stays on your device by default.
For users who want the most sophisticated adaptive macro coaching available, MacroFactor remains the specialized choice for that purpose. For users who need both nutrition tracking and injectable protocol management in one offline-first app, Redose covers the full picture without requiring two separate tools.
