Blekk is your notebook, task tracker, journal, and scratchpad - simple, elegant, and focused. One fresh page for each day, all on a single scroll. Not every note needs a formal notetaking app. Blekk is for the things you jot down but don't always know where to stash. There is nothing to set up and nothing to organise. Open it and today is waiting for you. Write, and it saves as you type. Late nights stay on one page: the day turns over at 5 AM, not midnight. Type a task and it becomes one, with a checkbox. Yesterday fades behind today, every past day stays in the scroll, and anything you've ever written is a search away - your words, your tags, the themes rising in your writing. The past stays reachable, without pulling focus from today. Blekk is a quiet place to write anything and everything. Welcome. Also: • Keep more than one notebook, each with its own pen and ink - one for work, one for the garden, one for the book you keep meaning to write • Lock any notebook with a PIN • Choose warm cream or stone paper; night ink comes on after dark • Share a notebook with your team, then return to a personal space that stays separate • Works fully offline; sign in and your words follow you everywhere, encrypted at rest • Export everything as plain markdown, any time - your notes are yours, and reading them is never paywalled • No AI. No feeds. No streaks. No distractions. Free for 30 days with everything on. After that, the basic plan keeps one writing device, with reads and export everywhere, forever. Blekk Plus adds unlimited notebooks and writing from every device. Teams bring shared notebooks with per-seat billing. Blekk Plus and Teams are auto-renewable subscriptions, billed through your Apple ID. Payment is charged at confirmation of purchase; the subscription renews automatically unless cancelled at least 24 hours before the end of the current period, and can be managed or cancelled in your Apple ID account settings.
