Challenge
Barter depends on trust and convenience: people need to post quickly, find a matching offer and close the deal safely. The app had to work on three platforms at once.

Feed, listings, offers and trades, profiles and SMS sign-in; reporting, blocking and account deletion.

Result
The app builds successfully for the iOS simulator and the web, and automated tests pass. Final settings for App Store and Google Play release are being prepared.
Key features

Feed and listings
