RedoseIf you are searching for a Phaze alternative, you have probably hit a point where your tracking needs have grown beyond what your current app covers, whether that means handling research peptides alongside your GLP-1, logging calories and macros in the same place as your injections, doing reconstitution math, or just wanting a tool that works equally well on iPhone and Android. Redose is a purpose-built injectable and nutrition tracker designed to cover that full range without asking you to switch apps as your protocol evolves.
What Phaze does well
Phaze has built a focused experience around GLP-1 weight-loss tracking. It gives users a clear way to log their medication, follow their weight progress over time, and stay on top of a structured program. For someone who is primarily using a single GLP-1 pen and wants a clean, goal-oriented interface centered on weight loss, Phaze serves that use case in a straightforward way. The emphasis on habit and motivation within a weight-loss context is a genuine strength for that specific audience.
Where Redose is different
Redose starts from the same core need (making injection logging effortless) and builds outward to cover a wider range of protocols and use cases, including the nutrition side that matters just as much when you are on a GLP-1.
Calorie, food, macro, and water tracking built in. Redose tracks what you eat and drink alongside every injection. You can log meals, review macros, and hit your daily water target without leaving the app. This matters for GLP-1 users in particular because the medication works alongside dietary changes, and having both in one log makes it easier to spot patterns and share a complete picture with a provider.
Breadth across GLP-1 and research peptides. Redose tracks GLP-1 medications like semaglutide and tirzepatide alongside research peptides such as BPC-157, TB-500, and others. You can run multiple active protocols at once, each with its own schedule, vial, and log. There is no need to manage a second app when your protocol changes.
Body-map injection-site rotation. Every dose log in Redose includes an injection site selected on an interactive body map. The app records your rotation history so you can spread injections across zones, which matters for consistent absorption, and review exactly where each shot went months later.
Built-in calculators. The calculators page handles reconstitution math, dose-to-volume conversion, and syringe unit conversion. You enter your vial concentration once and the app fills in the numbers for each dose. This removes the most common source of dosing errors for anyone working with lyophilized powder.
Live vial and pen inventory. Redose tracks how many units or doses remain in each vial or pen and sends a reorder reminder before you run out. The inventory updates automatically each time you log a dose, so there is no separate step.
Offline-first and private by design. Redose writes every log to your device first. A lost signal, a flight, or a weak connection never blocks you from recording a dose or a meal. Data stays on your device and syncs to your account only when you choose.
Cross-platform, one account. Native iPhone and Android apps share the same protocol and history under one account. If you switch phones or use both, your full record follows you.

Who should choose which
Choose Phaze if your goal is primarily weight loss on a single GLP-1 medication and you want an app that frames everything around that objective, with motivational tools and a weight-loss program experience at the center.
Choose Redose if you want a tracker that handles the full injection workflow alongside your nutrition, from reconstituting a peptide vial to logging a weekly GLP-1 shot with site rotation, side-effect notes, calorie counts, and water intake. Redose is the better fit when you are managing multiple compounds at once, need the built-in calculators, want calorie and macro tracking in the same place as your dose log, care about a shared record across iPhone and Android, or want your data to stay private and available offline at all times.
Both apps serve GLP-1 users, but they are optimized for different priorities. Phaze leans toward the weight-loss journey with a structured program feel. Redose leans toward the complete protocol and nutrition picture, whatever that protocol contains.
