Walmart Supercenter·SEP 20, 2026
Scanning receipt…
Amounts match.
Know where it goes.
Snap a receipt. Catch price creep. No bank login, and your photos stay on your phone.
In closed pilot on Android · iPhone in TestFlight.
The little things add up.
Your bank app knows what you spent. It can’t tell you what anything cost.
Same bananas, higher unit price
Bananas went from $0.89/lb to $1.07/lb at Costco. Your receipts catch the creep, unit by unit.
Receipt category beats merchant category
Your bank sees one Costco charge. Your receipt sees groceries, gas, and dinner: sorted line by line.
Spending, item by item
Not just where the money went: what it bought. Every receipt becomes searchable history.

Questions about receipts, privacy, and launch.
Do you sell my receipt data?
No. Your photos never leave your phone: scanning happens on-device, and only the extracted text goes to our cloud proxy for parsing. No ads, no bank logins, no data sale.
Is it really free? What's the catch?
No catch. Cloud scans will be free and unlimited at launch. A Pro tier comes later. The launch list hears about it first.
Why not just use my bank's app?
Your bank sees $84.12 at the grocery store. Your receipt sees milk went up 7%.
Will I actually stick with it?
There's no typing items in by hand: snap the receipt, review the draft, move on. No spreadsheets, no bank syncing, no setup.
What if the scan gets something wrong?
Every receipt opens as an editable draft. Fix items, tax or totals in a tap. The digits on the receipt always outrank the AI.
Will it read a crumpled receipt?
Crumpled, faded, even upside down: it's built for real-world receipts. The printed total anchors every draft, so you always have a check.
Can I back up or delete my data?
Backups are optional, to your own Google Drive or iCloud. You can delete your account anytime at mappingbills.com/delete-account.
When can I get the app?
It's in closed pilot on Android now; iPhone is in TestFlight. Join the launch list and we'll tell you the moment it's public.
