Most of these apps I've used over the years in my fitness journey. For this list I looked at the following factors:

Customization: A great fitness app will allow you to customize your workout plan to your fitness level, preferences and goals.

Comprehensive approach: I looked at apps that offer a holistic approach and incorporate different exercise types (like cardio, strength training, yoga and more), nutrition, mental health exercises and guidance.

Support features and community: I especially like apps that foster a supportive community where women can share experiences and successes.

User-friendly interface: An app's interface plays a crucial role in your fitness journey. I looked for designs that are intuitive, easy to navigate and give clear guidance that contribute to a positive user experience.
