WithU — Capture and celebrate friendships on iPhone

WithU is an iPhone app created to help people record and deepen their friendships through playful, photo-based interactions. It focuses on real-time shared moments and a set of playful mechanics that encourage frequent, meaningful contact between friends.

Core functions and interaction tools

• Companion meter — A visual display that highlights the friends you photograph most often, showing their icons prominently to illustrate who you share the most memories with.
• Bolt reaction — A vibrant way to respond to friends’ posts: spend collected energy to send a bold “bolt” reaction that expresses stronger feelings than a simple like.
• Emotion charge — Earned by taking photos together, this temporary energy gauge grows when you capture moments with friends and fully decays after 24 hours, motivating regular check-ins.
• Group shutter — The app’s synchronized camera unlocks when nearby friends are detected, allowing everyone to take photos at the same moment so shared memories are captured simultaneously.

Alternatives

• Suggested alternative: Mirror — free

Purpose and design intent

WithU aims to make friendship more engaging by combining co‑captured photos with lightweight, emotionally expressive mechanics. The temporary energy system and realtime capture features are designed to encourage frequent, creative interactions and to visually celebrate the people you spend time with.
