Organize into separate categories. Export PDF reports (Premium). Examples: 11:20 AM → 12:40 PM = 1h 20m 01:30 AM → 02:30 PM = 13h Today 02:00 → Tomorrow 02:30 = 24h 30m DATE CALCULATOR (ADD & SUBTRACT) From any starting date, add or subtract years/months/weeks/days/hours/minutes to get the resulting date.

ProofLater

ProofLater helps you save receipts, invoices, purchase proofs, and supporting evidence in one calm, organized place — then understand why those proofs may matter later. Instead of only scanning and storing receipts, ProofLater is designed to help users see: * what a proof may be useful for later * how long it should be kept * how strong the proof is * what extra evidence may make it more useful in the future Whether it is for returns, warranty claims, travel reimbursement, taxes, insurance, repair support, or resale, ProofLater helps keep important proof ready when it matters. WHY PROOFLATER FEELS DIFFERENT Many receipt and warranty apps focus on scanning, storing, organizing, and reminding. ProofLater goes further by helping users understand the future value of what they save. Instead of just saying “receipt saved,” the app helps answer: * Why should I keep this? * What might I need it for later? * Is this proof strong enough? * How long should I keep it? KEY FEATURES Import Proofs Easily Add receipts, invoices, order confirmations, screenshots, PDFs, warranty papers, and other purchase-related files from camera, Photos, Files, or share sheet flows. Extract Useful Details Detect important information such as merchant, purchase date, total amount, and text from scanned or image-based proofs. Search Fast Search proofs by merchant, date, amount, proof type, order reference, category, note, or keyword. Organize in Human-Friendly Folders Keep proofs in simple folders such as Returns, Warranty, Tax, Travel, Business, Insurance, Big Purchases, To Review, and Saved Important. Attach Supporting Evidence Strengthen your proof by adding related items such as product photos, serial numbers, warranty cards, packaging labels, or confirmation emails. Set Helpful Reminders Track return windows, warranty periods, reimbursement timing, and other deadlines tied to your saved proof. WHAT MAKES THIS APP STAND OUT Future Use Radar Future Use Radar predicts why a receipt or proof may matter later. Examples may include: * Return support * Warranty claim * Insurance proof * Tax documentation * Business reimbursement * Travel expense * Repair support * Resale proof * General proof of purchase This helps users understand the real-life purpose of keeping a proof instead of only storing it. Proof Strength Proof Strength gives each saved proof a practical score showing how complete and useful it may be later. For example, the app can consider whether the proof includes: * merchant name * date * amount * item or product details * order number * serial number * attached product photo * warranty support * readable image quality The app can then suggest ways to improve the proof if needed. Keep Until Guidance ProofLater helps users understand how long a receipt or proof should be kept based on its likely future purpose. Examples may include: * Keep until return window ends * Keep until warranty expires * Keep until reimbursement is approved * Keep until tax filing is complete * Keep until insurance claim is resolved MADE FOR REAL LIFE ProofLater is built for ordinary users who want a better way to manage receipts and purchase proof without turning the experience into a complicated accounting workflow. It is designed to be simple, clear, useful, and fully focused on helping people stay ready later. FULLY FREE ProofLater is fully usable without locking essential features behind a paywall.
