Built together

Five strangers. A few hours. One working prototype.

01 / Primtal

A full calendar. Little room for you

A calendar shows where your time goes. It rarely shows how you feel. We built Primtal to connect a short wellbeing check-in with a practical change to the day.

  2. 02See patterns
  3. 03Consider a change
  4. 04Confirm it
02 / Slack

A check-in inside Slack

Six questions about mood, enjoyment, calm, energy, focus and digital balance — inside a tool the team already uses.

A little perspective over time

The prototype charts check-ins to make patterns easier to see. The values shown are demonstration data, not a clinical assessment.

03 / Ambiguous

From a conversation to a clearer day

I coded the Ambiguous version as my part of our shared project. A short conversation leads to a suggestion, while the user stays in control.

04 / Calendar

You choose what changes

Primtal suggests protecting an hour for focus. Only after confirmation does it add the event to the calendar.

05 / Strangers to teammates

Strangers to teammates

We had just met. We found our roles, shared responsibility as equals and built Primtal together. The Slack and Ambiguous versions were parts of one team project.

I’ve never found a working rhythm with people I’d just met this quickly. I’m really glad I met this team.Alex SOLONSKY
