Sitra is not just another to-do list. It is a context-first task app that helps you remember what a task is about, not just that it exists. Instead of splitting notes, files, links, recordings, schedules, and action items across different places, Sitra brings them together around a situation. Once the context is in place, you can turn it into clear next actions, focus on what matters today, and return to work without losing the thread. With Sitra, you can: organize notes, files, links, and recordings by situation manage today’s tasks and upcoming work in one flow keep schedules and actions connected to the right context transcribe recordings and turn them into summaries and follow-up tasks use AI organization, draft generation, and project-aware AI chat when you need extra help quickly resume recent work without digging through multiple apps Sitra is a good fit if you: want tasks to stay attached to real context often lose momentum after meetings or voice notes want notes and action items to live in the same workflow prefer a calmer, clearer way to manage personal work Privacy and storage: app data such as notes, files, recordings, and transcripts is stored on your device by default only the minimum account, authentication, and billing information is processed for service operation text is processed only when you explicitly use AI features Sitra is built to help you move from scattered context to clear action.

About

Gridpaper

Gridpaper doesn't draw the picture for you. It just makes a blank page easier to start. Gridpaper brings your to-dos, events, yearly goals, and a diary you can decorate into one place. β–  Fill in your day, one square at a time Move between Day and Week as you write. Tag a to-do and it joins that tag's own section, marked with a small patch of color. Check something off to fill its square in. Nothing disappears β€” the line just moves down the list. Press and hold a to-do to move it to tomorrow, repeat it tomorrow, or send it to another date. β–  Turn repeats into routines Set a to-do to come back daily, on certain weekdays, or on whatever schedule suits it. Skip a single day when you need to, and the rule stays as it is. β–  A whole month on a single page Keep events and diary entries together on the calendar. If you like, days you finished your list can keep a small mark β€” in a color you choose. β–  A diary you can decorate Add photos, tilt them, and trim them into the shape you want. Lay text and stickers on top to make the page your own. Every entry you write sits as a small thumbnail on its day in the calendar. β–  Count your year in squares Set a yearly goal and break it into milestones β€” or into a count, like 24 books, with a grid you fill one cell at a time. Send a milestone to your to-do list whenever you're ready to work on it. β–  Paper and ink Clay-white paper, ink-dark text. Ink is the only color the app puts down on its own β€” the rest is yours to add. Ten traditional Korean colors, drawn from dancheong painting and jogakbo patchwork, color your tags and goals. β–  Where your writing lives Everything stays on your device and in your own iCloud. Nothing is sent to a developer's server, and the person who made this app cannot read it. Your records show up on every device signed in to the same Apple Account. β–  Two languages Gridpaper is written in Korean and English. If your device is in one language but you'd rather read the app in the other, you can set the app's language on its own.
