🌍 Remote, USA 🎯 Full-time 🕐 Posted Recently

Job Description

SEE PDF for screens.

We are building a next-generation health app for a smart weight scale and are looking for a skilled Flutter developer to help us turn our existing Canva design into a fully working MVP and launch it on both iOS and Android.

You will receive the Canva Design and a Bluetooth protocol from the scale manufacturer. The goal is to go from design → working app → App Store / Google Play submission. We will also send you the actual scale so you can try it.

About the App

The app is a companion app for a smart scale that measures body composition and calculates health scores.

The MVP consists of:

Onboarding flow

3 main screen types (Home, Category, Detail – see PDF)

Settings

Bluetooth connection to the scale

Authentication (account creation, login, password reset)

Smooth transitions, basic animations, and micro-interactions

Tech Requirements

Flutter (single codebase for iOS + Android)

Bluetooth Low Energy integration (we provide full protocol from hardware partner)

Authentication flow (email + password, reset)

Basic charts (time series, trends, population ranges)

Clean architecture so the app can scale later

We will:

Provide full UI in Canva + PDF

Provide Bluetooth protocol

Ship you the actual smart scale so you can test with real hardware

Handle App Store / Play Store texts, screenshots, and branding (you focus only on technical submission)

Budget & Long-Term Vision

Budget for this MVP is $600. I know this is below standard rates, but I am bootstrapping this company myself. I am planning to raise funding in March once the MVP is live and then we are able to pay more. At that point, the right developer will:

Continue as our long-term Flutter lead

Become part of the core team

Own the app architecture and future features (AI insights, subscriptions, advanced analytics, etc.)

This is not a one-off gig. This is the start of a long-term product.

What We’re Looking For

Strong Flutter experience

Experience with BLE / hardware integration is a big plus

Ability to move fast and build clean MVPs

Product mindset (not just “ticket execution”)

Someone excited to grow with an early-stage health tech startup

Deliverables

Fully working Flutter app (iOS + Android)
