### 1/5 — Won’t give me a way to request early access

*2023-10-02*

What is the point of all the updates I have been receiving over the last two years? If I can’t logon at all.

### 5/5 — Great app!!

*2024-02-14*

What a great app!! Easy to use and provides valuable insight to sleep, exercise and other metrics. Syncs up seamlessly with my Apple and Fitbit wearables. The daily scoring system is an aggregation of key foundational pillars of health, and simplifies our personal health assessment and improvement journeys. One of my top 10 used apps. Terrific job Serotonin team!
