7 days
from broken to live on iOS and Android
A broken booking app, rebuilt in 7 days
Engineer, start to finish
Fixing it was estimated at 100+ hours. I rebuilt it instead, and it was live on both app stores in a week.
Signups and bookings were failing. The rebuild added payments, maps and instant updates that skip the app store queue.
Before launch I tested it the way real people break apps: dropped signal, expired logins and double taps.
