NEW: RECEIPT SCANNER
Point your camera at a receipt and every price lands in a Math Note, ready to add up:
✓ Each item becomes a named value, like "Rice = 45", with a total line that adds them for you
✓ Check the scan before saving: untick rows, fix a name or price, and see if it matches the receipt's own total
✓ Understands tables, tax, discounts and insurance
✓ Long receipts? Scan up to 3 pages at once (Premium)
✓ Split the bill or convert the total to another currency in one tap
✓ The receipt photo is kept with the note
Receipts are read on your phone and never uploaded. Get 3 free scans every month, or scan without limits with Premium.
