Peptide Tracker & Calculator Puts Dose Records and Maths Together

A dose record can start simply enough: write down what you took and when. The trouble begins when the record also needs injection sites, titration phases, vial contents, reconstitution maths and a view of how doses may overlap. A notes file can hold some of this information, but it does not do the arithmetic for you. A spreadsheet can do the arithmetic, but it takes more work to maintain.

Peptide Tracker & Calculator is an iOS app built around that gap. It combines a GLP-1 dose log with schedules, inventory records, a reconstitution calculator and half-life visualisation. The intended user is someone following a prescribed GLP-1 or peptide protocol who wants a consistent personal record, not an app that decides what the protocol should be.

The basic record is more than a timestamp

The quickest path is a one-tap dose entry. The app also supports fuller records containing the amount, unit, time, injection site and notes. That gives the log enough context to be useful later, particularly if a person wants to see whether they have been consistent or provide a record to a healthcare professional.

Schedules cover daily, weekly and interval dosing. The description also says users can create multi-phase titration plans with custom durations, maintenance phases and pauses. A timeline shows current and upcoming phases, while reminders can be paused or saved as reusable templates. The app includes missed-dose detection against a recent schedule window, although the supplied information does not explain the exact lookback period.

Injection site tracking is another practical detail. Users can record sites, rest days, usage frequency and reactions. There are also tools for side-effect records, including severity, photos and interventions. These features make the product more useful than a plain semaglutide tracker or tirzepatide tracker, but they still depend on the user entering information accurately and consistently.

Where the calculators fit

The calculator side addresses the work that often sits separately from a dose log. It can handle reconstitution volumes, concentration per unit, dose-to-volume conversions and syringe units. A blend breakdown is also listed. The half-life visualiser plots decay curves and can show scenarios involving steady-state peaks and time to target levels.

That combination is the app's clearest reason to exist. A user can keep the inputs behind a calculation alongside the dose history instead of copying numbers between a notes app and a spreadsheet. The result is still only a calculation based on the values entered. It is not a dosing recommendation, and the app does not interpret whether a result is appropriate for a particular person.

The landing page also describes compound and brand presets, including products such as Wegovy, Ozempic and Mounjaro, as well as custom compounds and blends. Those presets may reduce data entry, but they do not remove the need to check concentration, vial details and units against the actual product being used. An arithmetic tool is only as reliable as those inputs.

Inventory and privacy are part of the workflow

The app is designed to track more than the next scheduled dose. Inventory entries can cover vials, pens, sprays, topicals and oral products, with fields for stock, expiry, batch, price and storage details. Logging a dose is said to deduct from stock automatically, and deleting an entry restores it. There are also records for bacteriostatic water, including volume, punctures, opening date, expiry and usage history.

This could be useful for someone managing several compounds or supplies. It also adds setup work. Inventory is valuable only if it is kept current, so users who want a quick log and nothing else may find the broader system more effort than they need.

Privacy is a stronger part of the pitch. Records are stored on the device by default, with no account required for basic use. The landing page says iCloud backup or sync is optional and uses the user's Apple account. That makes the app more suitable for people who do not want to upload health records to a service by default, though an iCloud setup introduces a separate decision about where a backup is stored.

What it does not do

This is an iOS-only product. There is no Android, web or desktop version in the supplied platform list, so it is a poor fit for anyone who needs access outside an iPhone. It also is not a clinical record system or a source of medical guidance. The developer states that it has not been reviewed or cleared by a regulator, and that it provides no dosing recommendations or clinical interpretation.

The app has a free plan with a paid upgrade. The supplied information does not specify which features require the upgrade, so that distinction is worth checking before building a workflow around a particular tool.

Peptide Tracker & Calculator makes sense for people on prescribed GLP-1 or peptide protocols who want one private iOS record for doses, schedules, supplies and the associated arithmetic. It is not for someone seeking treatment advice, automatic clinical decisions or a cross-platform tracker. Its usefulness rests on careful inputs and disciplined logging, not on the app validating the protocol itself.
