Sheet Notes
Read full descriptionHide full description
Sheet Notes: Notes in a Grid Sheet Notes is a flexible workspace for people who find linear documents too restrictive and spreadsheets too rigid. It organizes your ideas into a grid where every cell acts as a Markdown-ready canvas. How it works: * Grid Layout: Move beyond lists. Structure projects and data in a layout that follows your thought process. * Full Markdown: Use rich text, headers, code blocks, and images within any cell. * Seamless Sync: Works across iPhone, iPad, and Mac via iCloud, with an optional GitHub sync for version control and sync to other platforms like Windows. * Privacy First: Your data stays on your device. It’s fast, works offline, and doesn’t track you. * Customization: Choose from themes like Midnight or Sand, or build your own to suit your workflow. It’s a simple, non-linear way to keep your research, writing, and planning organized without the overhead of a complex database.
Zonal

Zonal is a tiny, focused time-zone buddy. Add the cities and people you care about and see at a glance, what time it is for each of them right now. Need to find a slot that works across zones? Drag the dial at the bottom to travel up to 24 hours forward or back and watch every clock move together. When you find the moment, you've found your meeting time. • Every card is tinted by the local time of day there — night, dawn, day, dusk — so you can feel the time, not just read it. Each card shows its own date, too. • Name your entries. The name starts as the city but you can call it anything — "HQ", "Mom", "Tampa". Add the same zone more than once under different names. • Tap any card for its detail page: live time, UTC offset... Set it as your base and every offset is shown relative to it. • Smart search knows common cities that aren't official time-zone names — Beijing, San Francisco, Antwerp, Mumbai, and over a thousand more — plus UTC and GMT. • Share an entry as a link; the person you send it to gets a preview and confirms before it's added. No accounts, no subscriptions, no ads. Zonal works entirely on your device.
