GLP Fish: Weight Loss Tracker

Coming soon iPhone · 7 languages

Treatment runs in months.
Your record should keep up.

Thinking about a GLP-1 medication, or already on one? Semaglutide or tirzepatide, weekly shot or daily pill — how your body responds and what you achieve deserve a proper record.

GLP Fish is built around three things: a forecast anchored to published studies, one timeline for weight, doses and costs, and a record that survives every pause.

Forecast. Record. Resume.

Three things, done properly

Forecast, record, resume

Everything else in the app supports these three.

Forecast

From your starting point and published clinical studies, GLP Fish shows the most likely weight path. Every curve names the study behind it, so you can check the source yourself.

Record

Weight, doses and costs sit on one timeline. Readings are corrected for how you weighed in, injections and pills stay separate, and spending is kept in your own currency.

Resume

Pausing erases nothing. Weight through a pause, results through maintenance, and the same record when you continue — each stage is its own chapter.

In the app

What GLP Fish keeps track of

A record you can still read a year from now.

Your likely trajectory

Pick your medication and set your starting weight. Each curve is anchored to a published clinical study, source included — a researched pace to compare against, not a promise.

True weight, any time of day

Weigh in when it suits you. Readings are corrected by context — fasted, after meals, evening — so they compare fairly, and every corrected reading shows its confidence range.

Every dose, every cost

Log a dose in seconds: injection or pill, amount, time. Shots and pills stay separate, and costs are recorded in your own currency, clear by stage.

Pausing is often good news

Hit your target and pause on plan — each stage is its own chapter, not a broken streak. Your history stays put, and maintenance is tracked the same way.

Your market, your language

Official medication information is matched to your market — FDA, PMDA, EMA, MFDS, TFDA — and opens right in the app. The interface is available in 7 languages.

Beyond the scale

Meals and protein logged next to your weight, plus body measurements such as waist and hips — change isn't only on the scale.

Who it's for

Four moments in a course of treatment, all on the same record.

Starting your first dose and want clean records from day one.

Paused at your goal, watching whether the weight holds.

Ready to resume and continue the same record.

In maintenance, keeping this stage on file.

Your data, handled honestly

Health records are sensitive, and GLP Fish treats them that way:

We never sell your data. There are no advertising SDKs, and health records are not shared with third parties.

Sign in and your records sync across your devices. Delete your account and the cloud copy goes with it.

Local data stays protected; if cloud data can't be read safely, GLP Fish refuses to load it rather than overwrite yours.
