18 Minute Workout: Custom Fitness App Development
Project Overview
Net-Craft developed the 18 Minute Workout app for The People’s Chemist, bringing its fitness program into an easy-to-follow mobile experience. The app combines structured exercise routines, workout timers, and daily habit tracking to help users stay focused on their next step.
Users choose a workout category and difficulty level, then follow visual exercise demonstrations with preparation, activity, and rest timers. Beyond each session, a Discipline Dashboard helps users track the program’s three core habits and review their consistency over time.
The goal was simple: make it easy to start a workout, follow the routine, and keep coming back.
App Features
Workout Categories and Difficulty Levels
Users can explore Smash Ball, Body Weight, Dumbbell, Y-Bell, and Black Belt routines. Beginner, Maintenance, and Extreme levels help users choose the right starting point for their training.
Clear workout previews show the exercises and timing before a session begins, so users know what to expect.
Guided Exercise Sessions
Visual exercise demonstrations and on-screen countdowns guide users through each routine. Dedicated preparation, workout, rest, and completion screens make each stage easy to follow.
The interface keeps the current exercise and timer prominent, helping users spend less time navigating and more time working out.
Discipline Dashboard and Habit Tracking
The app’s Discipline Index tracks the program’s “Core 3” habits: Workout, Get Sunshine, and Quit Sugar.
Users log the previous day’s activity through a simple checklist. Weekly and monthly views display an overall progress score and separate habit charts, making it easy to see where they have been consistent.
Subscription Management
Monthly and annual subscription options give users a choice of plans. The subscription flow includes plan selection, access to premium routines, purchase confirmation, subscription restoration, and current plan details.
Step-by-Step Onboarding
An illustrated introduction explains the program, dashboard, and training approach. Short screens encourage users to focus on exercise form, track their habits, and spend time at each level before moving forward.
