Burn451 is a reading tool that helps you save links, read them later, and decide within about 24 hours whether to keep or let go. Too many saved pages never get opened. Burn451 gives each new save a short window: open it in a clean reader, then keep it or release it. What you choose to keep can move into Spark and then Vault, so your library stays intentional. What you can do: • Save links from Safari or any app with the Share Extension. • Read in a clean, focused reader without ads or clutter. • Find pages again with full-text search. • Organize saved pages with tags. • Keep a Spark and Vault workflow for what is worth keeping. Optional AI-assisted features can help you review what you saved. They are not included for every account, and this listing does not promise free AI for all users. You decide what stays. Unread items can expire. Burn451 does not permanently delete every link after 24 hours. If a page cannot be extracted, that save is held and does not burn. You can retry extraction or paste the text. Listen with system text-to-speech in the reader. Export from Vault, including Markdown and a direct Obsidian folder export, is available and is not sold as a Pro-only feature. Full-text search is available to every account. Privacy first. Your reading stays yours. No ads. No selling your data.

Some thoughts are meant to be written down. Not all of them are meant to be kept. Fire Notes is a private notebook with one unusual feature: you can burn a note. Fire, rendered live on your screen — the paper catches, chars and falls away as ash. When the flame goes out, the note is gone. It's oddly satisfying. It's also the point. WRITE ANYTHING • A fast, beautiful editor with rich text, checklists, headings and highlights • Choose your paper and your handwriting — from clean type to a looping script • Photos, shelves and compact pinned notes on a board you can rearrange by hand • Choose from 20 pin designs in one compact Settings gallery • Search notes and checklist items, duplicate a note, or shuffle loose notes with undo LET IT GO • Burn a note in a moment, or hold for the full cinematic ceremony • A slow, soft flame with drifting smoke, glowing embers and falling ash • Use the microphone or press and hold to light the flame • Set an auto-burn timer when a note is only for now • Ashes records released notes with a date and an optional one-word tag SCAN YOUR PAPER • Scan receipts, bills and letters, or import photos and PDFs into a multipage document • Find page edges, correct perspective, crop, rotate and adjust the image • Clean up the page with filters; duplicate a page or apply one filter to the whole document • Add pen marks, highlights or handwriting, with undo for page edits • Read and correct recognized text on your device, then find a scan by the words inside it • Export a searchable PDF, page images or plain text, with the current page order and markup • Keep documents in their own shelves, show one on Home, or move it to Shoebox when you're done CAPTURE YOUR VOICE • Record, pause, replay and seek through a voice note • Read, copy or retry its on-device transcript • Share the recording with its transcript, or keep it safely in Shoebox PRIVATE BY DESIGN • Notes and scans live on your device and in your own iCloud, never on our servers • Face ID app lock, plus a separate lock for the notes that matter most • Locked and sealed content stays out of previews and content search • No account. No ads. ALSO IN THE BOX • A gold capture button that catches the light as you tilt your iPhone • On-device AI to fix, rewrite or reshape your words on compatible Apple Intelligence devices • Export notes, checklists and drawings when you decide to keep them • Reduce Motion support and a readable menu for note actions FIRE NOTES+ A one-time purchase.
