App UX
The design principles behind the Wellex app.

One screen
The Today screen shows three things and only three things: today's WVI, today's direction, and yesterday's sleep chart. Anything else is one tap away.
One number
We resisted every temptation to add a second score. Two scores require comparison, comparison requires interpretation, interpretation defeats the purpose.
One direction
The app picks one specific action per day. We never show a list.
No attention economy patterns
- No streak counters.
- No achievements.
- No social leaderboards.
- No notification spam.
- No upsell screens.
- No daily-active-user incentives.
Voice and text
Headlines in Playfair Display, body in Onest, monospace numbers in JetBrains Mono. The numbers are big and quiet, the typography never shouts.
