Personal training app
Application for professional trainers and their clients that helps to stay fit
Short summary
Client: The target audience is professional sport instructors and their clients.
Need: To build two native apps for iOS and Android.
Challenge: We needed access to native APIs to make integrations with Apple HealthKit and Google Fit. It’s also necessary to face the fact that the retention rate of such apps has a room for growth, so the app should’ve been interestingly gamified, and we leveraged our knowledge to achieve it.
Solution: Due to the team’s experience in sports apps development, we managed to deliver a solution that meets all client’s requests in the short timeframes and with no budget overburn.
Impact: We observed at least a 30% customers retention rate for gyms and personal trainers thank to the constant communication and progress tracking enabled by the new mobile app.

What’s the app for?
While people try to take on new habits, they need a companion to make the process easier. A personal training app that we’ve built assigns a professional trainer to each user who wants to start exercising and eating healthy food. App allows tracking progress and suggests constant supervision from sport pros.
Trainer’s app
The application for trainers provides a set of features allowing them to oversee clients’ progress. Trainers can set up a meal plan, schedule trainings in details, control body client’s parameters’ changes, watch training history, etc.
Client’s app
Clients’ apps are tigthly connected with the ones for trainers. Once sport pros add some new info to users’ profiles, they can see it on their mobile phones. So, when the meal or a training plan is set up, it’s available on the clients’ apps at once.
Core features
Simple and convinient client list
On this tab, trainers see the list of their clients along with the goals each of them follows, such as leaning body mass, weigth loss, or keeping fit.
Easy meal planning
According to the goal clients want to achieve, trainers draw up a nutrition plan for them that instatnly appears in the client’s mobile app.
Training programs setup
Trainers define a training schedule for the clients. Schedule includes the exercise sets, repetition number, and additional weights if necessary.
Training history
Both trainers and their clients can anytime access the history of trainings that includes calories burnt, weights used, and amount of performed sets.

This tab on the clients’ mobile apps include their achievements regarding body condition - changes in weight and parameters.
Progress tracking
Along with the healthy nutrition and exercising, users may want to acquire new habits. The progress tracking tab allows checking the completed goals, watching the progress in pictures and weight dynamics on a visual plot.
