LookDiff
See what changed: before and after photos, side by side
The Challenge
People often sensed that something changed at home, the office, or in a car but couldn't pinpoint what. Without a systematic way to capture and compare scenes, verification was impossible. LookDiff needed a simple flow: take photos when leaving, take photos when returning, and get a clear view of what changed.
Constraints & Requirements
- Before-and-after photo capture and secure storage
- Comparison and difference highlighting between photo sets
- Simple, intuitive flow for non-technical users
- Cross-platform iOS and Android with reliable photo handling
Our Approach
Discover
Researched user scenarios: home, office, store, car. Defined minimal flow: leave photos, return photos, compare.
Design
Designed capture flow, gallery, and comparison view with clear difference indication.
Build
React Native app with React Navigation and Redux. React Native Firebase for storage and auth. Image comparison logic.
Launch
Released on App Store and Play Store. Gathered feedback on comparison accuracy and UX.
Iterate
Added albums, reminders to capture, and sharing of comparison results.
The Solution
React Native app with before-and-after photo capture, secure storage via Firebase, and comparison view to highlight what changed, helping users verify changes at home, office, store, or car.
