Folio vs Sealed

Every PDF tool you need — and not one byte of your document ever leaves your device. Online PDF tools are convenient until you read the fine print. Your contract, your payslip, your client's financial statement — uploaded to a server you don't control, retained for purposes you didn't agree to, mined for data you didn't consent to share. Folio makes that trade-off unnecessary. Folio is a full-featured PDF toolkit that runs entirely on your iPhone and iPad. No network connection. No account. No cloud sync. No analytics. Your files go in, your files come out — nothing in between. WHAT YOU CAN DO Organise — Merge multiple PDFs into one document — Split a PDF into separate files by page range — Reorder, rotate, or delete individual pages Reduce & Prepare — Compress PDFs to shrink file size without rebuilding content — Add watermarks or page numbers — Flatten form fields and annotations into a fixed document Convert (best-effort, on-device) — PDF to images: export pages as JPG or PNG — Images to PDF: combine photos into a single document — PDF to Word, Excel, or PowerPoint — conversion is handled entirely on-device using Apple's document frameworks; complex layouts may not reproduce with pixel-perfect fidelity, but no file is ever sent to a remote service to achieve it Protect — Password-protect a PDF with your chosen password — Remove password protection from a document you own Fill & Sign — Fill text fields in PDFs — Add your signature to any document Extract & Search — OCR: turn a scanned or photographed document into searchable, selectable text using Apple's on-device Vision framework — Extract all text from a PDF for copying or reference ZERO NETWORK DESIGN Folio ships with no networking capability. It cannot phone home. It cannot upload a file even if it wanted to. Every operation — compression, conversion, OCR, signing — runs on your device's own processor using Apple's built-in frameworks. This is not a marketing claim; it is a technical constraint we built in by design. This matters most when you are handling documents that should never leave your hands: NDAs, medical records, legal filings, HR documents, financial statements, tax returns. NO ACCOUNT REQUIRED Open the app. Use every feature. Close the app. No sign-up screen. No email address. No subscription prompt. No paywall on any v1.0 feature. BUILT FOR PEOPLE WHO HANDLE SENSITIVE DOCUMENTS Folio is built for lawyers, accountants, HR professionals, and anyone else who regularly works with documents that are nobody else's business — and for anyone who is simply tired of feeding their files to free websites that profit from what they read. Your documents are yours. Folio keeps them that way.

You think you know what will happen. Sealed makes you find out. Write a prediction, say how sure you are, and pick the date you will know. It seals. Until that date nobody can read it back — not even you. All you see is the label you gave it and a countdown. When the day comes, the seal breaks and you meet your own words: what you said, why you thought it, and how confident you were. Then you mark yourself right or wrong. That is where the interesting part starts. Sealed keeps the one number almost nobody keeps about themselves — how often the things you were 80% sure about actually happened. Say 80% and be right half the time and it will tell you so, level by level, and in plain words: "You say 83% on average and you are right 67% of the time. You run 16 points overconfident." Nothing leaves the phone. There is no account to make, no server holding your predictions, and nothing to subscribe to. It works on a plane. • Seal a prediction until a date you choose — minutes away or ten years away • Six confidence levels, each explained in odds you can feel • A vault of what is sealed, what is ready to open, and what you have judged • Your calibration, level by level, with a chart and a plain-English verdict • Reminders when something is ready to open, naming only the label • Export what you have opened as Markdown; sealed predictions are never in it • Sixteen example predictions to load, so the numbers mean something on day one • Works entirely offline. No account, no analytics, no subscription.
