I am looking for a developer to create a mobile app that will help people track their diet and exercise. The main goal of the app is to aid in weight loss, nutrition calorie tracking and fitness tracking. I have some ideas for specific features but I am open to suggestions. The app needs to be available on both iOS and Android platforms and need to have three languages (English, Spanish and Arabic) Ideal skills and experience for the job include:
- Mobile app development for both iOS and Android
- Experience with nutrition tracking and fitness tracking features
- Diet recipes
- Ability to create a user-friendly interface for easy tracking and input of data
- Familiarity with calorie tracking and meal planning
- Knowledge of push notifications and reminders to keep users on track with their goals.
- Ability to invite others through WhatsApp, SMS and email.
- Subscription plans and payments in the App
- Ability to log food and scan barcodes
- Intermittent fasting
- Workout plans
- Sync health apps and apple watch
- project has to be published under my account in App store and google play by the developer and all bugs solved
