Read full description

BIAS Writer is a markdown editor for novelists, note-takers, journalists, and students who want a clean, focused writing environment. A minimal interface that gets out of your way. Write in dark or light mode. Organize with projects, documents, and tags. Archive what you're not using. THREE TOOLS YOU WON'T FIND ANYWHERE ELSE Memos ((double parentheses)) — Leave yourself notes that stay visible while you write but never appear in exports. Research links, reminders, questions to resolve later. Omits [[double brackets]] — Keep alternate lines, deleted scenes, or backup text in your document but hidden from your final output. Cut without losing. Tags #hashtags — Mark chapters, status, characters, or anything you want to track. Filter your entire project instantly. SEARCH ACROSS EVERYTHING Find any word across all your documents. Switch to Memos, Omits, or Tags mode to search only those. Jump directly to any result. EXPORT CLEAN Share as Markdown, PDF, HTML, or plain text. Memos and omits are stripped automatically — or include them if you want. SYNC WITH iCLOUD Subscribe to sync your writing across iPhone, iPad, and Mac. Your work is always with you. FREE TO TRY Write for 7 days. Subscribe to keep your work synced across devices.

Slips — Five notes, made yours Five slips. That's all. Slips is a notes app built on a simple idea: five fixed notes are enough for the things you actually return to, and few enough that you always know where everything is. No folders to organize, no archive to dig through, no blank-page guilt. Pick a slip and write. MADE YOURS Name each slip, choose an icon from hundreds of symbols, and give it a color. Groceries, Books, Trips, Meds, Faith, Projects, whatever your five are. Reorder them any time. ALWAYS IN SYNC Your slips live in your own private iCloud and stay current on iPhone, iPad, and Mac. Edit on one device, and it's on the others. Nothing is collected, nothing is tracked, and there are no accounts to create. BACKED UP, JUST IN CASE Every device quietly saves a daily backup of your slips, keeping the last three. Restoring takes one tap, and a safety copy is made first, so even a restore can be undone. You can also export your slips to a file and keep it anywhere. RICH WHERE IT COUNTS Bold, italic, underline, highlight, headers, bulleted and numbered lists, tap-to-check checklists, dividers, and links that turn into preview cards. FAST WAYS IN Add to a slip from any app with the share sheet. Automate with Siri and Shortcuts. Put a slip on your Home Screen or Lock Screen with widgets, or capture instantly from Control Center. AT HOME ON THE MAC A real Mac app: your slips in the sidebar, formatting in the menu bar, Cmd+1 through Cmd+5 to switch slips, an optional menu bar icon, and sharing straight from Safari. SIMPLE PRICING Try a single Slip for free forever. Slips Plus unlocks all five. One purchase covers iPhone, iPad, and Mac, and is shareable with your family. Slips Plus subscriptions renew automatically until canceled in your App Store account settings, at least 24 hours before the current period ends. Lifetime is a one-time purchase.
