Gain completely replaced the stack of apps I used before. The UI is clean and intuitive, it's rock solid, and the flexibility to customise everything per client is unmatched.

Since switching from Google Sheets to Gain my coaching workflow has become so much smoother. My clients get clear structure and everything lives in one place.
