Mobile App Development
Gym Training App – Daily Workouts & Morning Check-ins
An Android and iPhone app that schedules each day’s training course and checks in with trainees every morning on the previous day’s session.
Project Overview
The Challenge
Trainees make the most progress when they follow their programme day after day — but motivation slips and trainers cannot personally follow up with every member each morning. The gym wanted an app that keeps every trainee on schedule and makes daily accountability automatic.
Our Solution
We designed and developed a mobile app for Android and iPhone that schedules a training course for every day of a trainee’s programme. Each morning the app messages the trainee to ask whether they completed the previous day’s session, with one-tap answers, and then presents that day’s workout with exercises, sets and reps. Progress is tracked across the week so trainees can see their streak and stay motivated.
Built with Flutter & Dart
Flutter & Dart Features Used in This App
The app is built with Flutter and written in Dart, so a single codebase delivers native apps for both Android and iPhone. Flutter’s widget system gave us full control over the design, while Dart handles scheduling, notifications and progress tracking behind the scenes.
One Dart Codebase
A single Flutter codebase compiled to native Android and iOS apps, keeping features identical on both platforms.
Scheduled Morning Notifications
A check-in notification is scheduled for each morning, asking whether the previous day’s session was completed.
Actionable Responses
Trainees answer with one tap, and their response is recorded against the previous day’s session.
Daily Course Scheduler
Dart logic lays out the programme day by day, so each morning opens with the right workout.
Push Messaging
Firebase Cloud Messaging delivers reminders and updates to Android and iPhone devices.
Reactive State Management
App state updates instantly as exercises are ticked off, keeping the plan and progress in sync.
Progress & Streak Tracking
Completed sessions roll up into weekly progress and streaks that keep trainees motivated.
Custom Widgets & Animations
Custom Flutter widgets and smooth animations create a polished, on-brand experience on every device.
