Mobile app for mental wellness startup

As a mental wellness startup, I'm looking for an experienced mobile app developer to help us create an app that will benefit our users. The app needs to be developed for both iOS and Android platforms and it must have self assessments, goal tracking, tips to improve, mindfulness exercises, and chat support. It is important that this project is completed within 3 months. If you have the skills to create this high-quality app, we welcome you to place a bid!
