Talktime – MVP application
The project
Mr. Sébastien Grember, founder of the TalkTime app, reached out to me to help design the interface of his mobile application. The goal of TalkTime is to encourage people to reconnect through phone calls at a time when we spend more of our days sending texts, snaps, voice messages, and so on.
The concept is simple: you swipe, just like on Tinder, and when you confirm with a right swipe, it launches a 1-minute call to the chosen contact. The idea is to “reconnect without dragging on.”
Problem
The founder of TalkTime needed a mobile app that would encourage people to reconnect through quick phone calls, at a time when messaging apps dominate communication.
Solution
Research
I designed the app interface with a “swipe like Tinder” contact selection, one-minute calls, gamified points, ringtones, favorites, and WhatsApp integration. Prototypes and wireframes ensured a smooth and intuitive user experience.
Outcome
The app offered a playful way to revive phone conversations, making calls short, fun, and rewarding, while giving the founder a strong product vision to move forward with development.
