Attach receipts that actually look like receipts.
NEW
• Scan-style crop for attachments — photograph a receipt or note and Debt Book finds the page for you. Drag the four corners to fit, and the crop is straightened out, so a tilted photo on a desk comes out looking like a scan.
• Crop photos before you save them — profile and contact pictures now open a Move and Scale screen, so faces stay centred instead of being cut off at random.
• Side menu — tap your photo on the Home screen for quick access to your books, book summary, search, settings and more.
• Your name, email and phone now appear as the "Prepared By" line on the PDF statements you share, so the person receiving one knows who sent it. Leave a field blank to keep it off the document.
• Pro members get a coloured ring around their profile photo.
IMPROVED
• Rewritten profile screen — every field is optional, empty fields read clearly, and the screen now tells you exactly where each detail is used.
• A Done button now sits above the keyboard on the search screen, so results are one tap away instead of hidden behind the keyboard.
• Bigger tap targets throughout the profile and contact screens.
CHANGED
• The free plan now covers 2 books, 5 people per book and 10 transactions per person. Payments and interest entries stay unlimited on every plan — once a loan exists you can always keep settling it. Everything you have already added stays exactly as it is, and Debt Book Pro removes every limit.
