tern is a booking app for yoga teachers, barbers and other people who work alone and hate answering the phone mid-session. When Ana Duarte came to us, the whole product was a photo of a whiteboard.
We spent the first week sketching on paper with Ana and three of her future customers. Paper is quick to throw away, and it keeps the conversation on what people need rather than on colours and fonts.
Testing every week
From week two we put a clickable prototype in front of real clients every Friday. The biggest change came from those tests: people wanted to see the next free slot before choosing a service, not after, so the whole flow was reversed.
tern launched in August. In its first month, 83% of started bookings were completed, a third more than the teacher’s old booking form.
