Overview
For someone new to the gym, the biggest problem is not motivation but not knowing what to do. Ready-made programmes online are written for everyone; they do not change with a person's goal, level or how many days a week they can train. The result is a programme abandoned after three weeks.
Yedfit builds the programme around the person. An eight-step onboarding flow captures goal, level, body type and weekly availability; an AI-powered programme engine turns those inputs into a weekly plan within seconds. Four goal types are supported, and the programme can be edited freely or continued from trainer-approved templates.
To stop people getting lost in the gym there is a library of more than 1,300 exercises. Every movement comes with an image and step-by-step instructions in Turkish — target muscle group, equipment used and correct form summarised in three points. A smart rest countdown between sets keeps the session moving without breaking rhythm.
On the progress side, the weights used are recorded; total movements, training days and weekly activity are tracked in charts. The user does not just feel progress, they can measure it. The app is live on the App Store and Google Play; it is free to start, with a premium tier offering an ad-free experience and advanced statistics.
