YQBuddy — Line-Standing & Task Service App
A dual-app on-demand platform connecting requesters who need line-standing help with buddies who complete the task — real-time tracking, OTP verification, and in-app wallet.
The problem
Line-standing is real paid work with no marketplace behind it: informal deals, no tracking, no proof the job happened, no payment protection.
The hard part
Two separately shipped apps over a single job lifecycle, with one-time codes at both the start and the end as the trust primitive — proving the buddy arrived and that they finished. Live map tracking during the job, and a wallet so payment isn't a card charge per task.
Outcome
Both sides of the marketplace shipped as separate apps, each live on the App Store and Google Play.
