Everything Your Fitness App Needs — Built In, No Coding Required
nandbox gives you a pre-built fitness app template with every feature gyms, personal trainers, fitness coaches, and wellness brands need to book more classes, retain more members, and build a motivated community.
Smart Class Booking with Real-Time Availability
Members discover available classes, see real-time capacity, pick a time slot, and confirm their spot in a few taps — with automated push reminders sent before every session. No more fully booked surprises, no more empty spots from forgotten no-shows.
Workout Programs & Personalized Plans
Create goal-specific workout programs — weight loss, strength building, flexibility, endurance — and organize them into separate tabs so every member finds a plan matched to their level and ambition. Personalized content increases session time and reduces churn dramatically.
Push Notifications & Workout Reminders
Send unlimited push notifications for class reminders, new workout releases, weekly challenges, motivational tips, and nutritional plan updates — all delivered directly to members’ home screens. Native push works even when the app is closed, at zero extra cost.
In-App Trainer Chat & Community Messenger
Trainers share guidance, tips, and encouragement through private chats and group channels. Members connect with each other in fitness communities of up to 50,000 people. A connected community reduces dropout rates and builds the social accountability that keeps people consistent.
Social Newsfeed & Content Channels
Keep your fitness community engaged between sessions with a scrollable newsfeed for workout updates, progress posts, nutrition tips, and motivational content. Members who engage with your content daily are far less likely to cancel — and far more likely to refer friends.
Secure Membership Payments
Accept monthly memberships, class pack purchases, personal training fees, and supplement orders through credit cards, debit cards, Stripe, and PayPal — all secured inside your branded app. Flexible billing options reduce payment friction and increase conversion to paid members.

- What Makes nandbox Different
Unique Features That Turn a Booking Tool Into a Complete Fitness Business Platform
Health & Fitness Progress Tracker
Members log workouts, track calories, count steps, monitor nutrition, and visualize progress over time — all inside your app. Seeing real results in a dashboard is the number one driver of long-term membership retention, and it keeps your app open every single day.
Wearable & Smartwatch Sync
Integrate with Apple Watch, Garmin, Fitbit, and other fitness wearables to pull heart rate, calories, sleep data, and activity metrics directly into your app. Real-time biometric data makes workouts more personalized — and gives members a reason to open the app even on rest days.
Fitness Challenges & Community Events
Run 30-day challenges, step competitions, weight loss sprints, and community workout events that members can join, track, and complete together. Friendly competition is one of the most powerful retention tools in fitness — and it costs nothing to run inside your app.
Ecommerce Store for Fitness Products
Sell gym gear, protein supplements, branded merchandise, and training equipment directly inside your app. Members who buy from you between sessions are more invested in your brand — and significantly less likely to switch to a competitor.
Booking Insights & Analytics
Track peak booking times, most popular classes, instructor performance, and member attendance trends in real time. Data-driven timetabling means you schedule more of what members want and less of what they skip — optimizing revenue and satisfaction simultaneously.
Gym Loyalty Programs & Rewards
Reward members with points for class attendance, workout streaks, challenge completions, and referrals — redeemable for discounts, free sessions, and merchandise. A loyalty program increases visit frequency, reduces churn, and turns your best members into advocates who bring friends.
