Illustrative trend, not your data.

Local-first. No account.

The trend engine

The scale is noisy. Your progress isn't.

Weight moves with water, salt, digestion, sleep, and cycle. 4.2 uses a time-aware EWMA trend, so a single heavy day does not become a verdict — and a real change does not get lost in the noise.

  • 7-day half-life trend; the first five records use a shorter window.
  • Long gaps restart the line instead of inventing data.
  • Outliers soften until several readings agree.
  • Goal dates use your recent 14-day rate — an estimate, not a promise.

GLP-1

A GLP-1 tracker that keeps the context.

A weekly injection is easy to lose track of. 4.2 keeps doses, symptoms, injection sites, titration, supply, and appointment notes in one private timeline.

  • Dose schedule, reminders, and injection-site rotation.
  • Symptoms recorded next to the dose timeline — without claiming cause.
  • Titration and label-based reference for 12 product entries.
  • Care Brief PDF, CSV, or print for your next appointment.

Doses & reminders

Log what you took, when, and where — with private local reminders.

Symptoms in context

See symptoms next to the dose timeline. No causal claims, no diagnosis.

Injection sites

Rotate sites with a body map and a record of what was used last.

Care Brief

Export a clean summary for a clinician — with privacy and range options.

GLP-1 tracking is a private record and education tool. It does not diagnose, treat, prescribe, or tell you to change a dose. Talk to your prescriber about your treatment.

Everything around the number

One app for the whole picture.

Weight is the goal. These are the tools: goals, measurements, nutrition, hydration, workouts, photos, and a home screen that fits the way you track.

A Home that fits your phase.

Start with fat loss, muscle gain, GLP-1, or habit. Add, remove, or reorder cards — Today stays fixed.

Scale themes

A little fun, every weigh-in.

Choose from 20+ scale themes — from clean dials to a friendly monster. The number is the same; the moment is a little lighter.

  • 20+ themes, including light, dark, and playful styles.
  • Your current weight and trend stay readable.
  • A small thing that makes opening the app easier.

Compare

Choose the app that fits the record.

We make one of the apps, so we disclose it. The useful comparison is concrete: what it tracks, where the data lives, and whether you can take it with you.

  • Trend, GLP-1, measurements, and nutrition in one place.
  • Local-first storage and no online account.
  • CSV, JSON, and local backup for portability.
  • Android-first, not an iPhone app adapted later.
Disclosure

We make one of the apps.

That is a bias. Our comparison pages use public information, state the date, and include “choose the other app if…” sections. If another app fits your needs better, we would rather say so than waste your time.

Connected & portable

Bring your data in. Take it out.

Health Connect can import weight and body composition from smart scales and health apps. CSV, JSON, and local backups keep the record portable — with optional password protection.

Privacy

Your health data stays on your phone.

No online account. No upload of your weight, GLP-1, nutrition, measurements, or photos. Export when you choose, delete when you want.

  • Local-first storage; health data and photos are excluded from Android cloud backup.
  • Encrypted export and import — your file, your destination.
  • Ads receive device-level metadata only, never your health records.
  • Anonymous usage analytics can be turned off in the Privacy Center.

Same app, current release

Built since 2013. Ready for what's next.

4.1 was the biggest update since the app launched: a new engine under the hood, the same app on your phone. 4.2 is the current release — with your history, goals, measurements, photos, and Pro purchase staying put.

  • 2013Weight Track Assistant launches

    Over a million installs later, the app is still in the same hands.

  • 2026Version 4.1 → 4.2

    The 4.1 upgrade brought a new trend engine, GLP-1, nutrition, and more. 4.2 is the current release.

  • NextSame app, continued updates

    No reinstall, no new account, no data migration on your side.

Same app

Same data. Same Pro. Nothing to migrate.

4.2 is an update to the same app — same package, same Play listing, same data. Just update from Google Play. On first launch, your existing data upgrades automatically.

  • Weight history, goals, measurements, and photos stay.
  • Existing Pro / ad-free purchases stay.
  • No new account. No reinstall.
  • Changing phones? Email support for a manual export/import.
Don't uninstall the old app before updating. Updating in place keeps your data; uninstalling can remove it.

Questions, answered.

Is 4.2 a new app?
No. 4.2 is the current release of Weight Track Assistant — same app, same package, same Play listing, same data. The 4.1 upgrade rebuilt the app; 4.2 continues it. There is no new app to install and no account to create.
Will I lose my data when I update?
No. Updating in place upgrades your existing weight history, goals, measurements, and photos automatically. Do not uninstall the old app before updating.
Does my Pro purchase still work?
Yes. Existing Pro / ad-free purchases continue to work in 4.2. No action is needed. If ads still appear, email support@weightasst.com and we will fix it.
Is there cloud sync?
4.2 is local-first. Your health data stays on your device and is not uploaded by the app. If you are moving to a new phone, email support and we will help you export and import your data manually.
Is the app free?
Weight Track Assistant is free on Android with ads. Existing Pro purchases stay ad-free. Health data is never used for advertising profiles.
Is this medical advice?
No. Weight Track Assistant is a record and education tool. It does not diagnose, treat, prescribe, or tell you to change a medication dose. Always talk to a qualified clinician about your health.
