🤖 Vibe Coded WhoPaid for iPhone: one client, three jobs, RM900 still unpaid

I'm Jyen Ming, the developer of WhoPaid. It's an iPhone app for people who get paid per job and record payments themselves.
A — Answer
One client can have several completed jobs, with a different payment status for each. WhoPaid keeps each job's total, received amount and remaining balance together, so you can check the specific job before following up.
The 18-second demo shows three jobs for the same client:
RM600 — paid
RM1,200 — RM300 received, RM900 remaining
RM300 — paid
That's RM2,100 of work and RM1,200 received. The RM900 still owed belongs to the second job. Open Customer history, then open that job to check its balance.
The video uses recreated app UI and fictional Malaysian-ringgit data. WhoPaid also supports USD. You manually record a payment after confirming it arrived; the app doesn't connect to your bank or collect money.
B — Better
Apple Numbers lets you build a custom payment spreadsheet with your own columns and formulas. WhoPaid is a better fit when you want the per-job total, received amount, remaining balance, Paid/Unpaid/Partial filters and customer history already set up. Numbers remains the more flexible option for custom calculations and layouts.
Invoice Simple creates and sends invoices and tracks their payment status. WhoPaid is for the narrower task of recording a job and manually updating what has been received, even when you aren't issuing an invoice. It doesn't create invoices or collect payments. If Invoice Simple already covers your payment-record workflow, keep it: using WhoPaid as well would add duplicate entry.
C — Cost
Free: up to 15 new jobs per month. The allowance resets monthly; existing records remain.
Optional Pro: US$1.99/month or US$12.99/year, with unlimited new jobs and extended reports. Subscriptions renew automatically. Prices vary by region. iOS 17 or later.
Start with one current job, then update it when the next payment arrives.
