Calcula is a lightweight scientific math keyboard for iPhone. After you add the keyboard, you can type expressions in chats, notes, browser search bars, or any system text field, and insert the result at the current cursor position. Version 1.0 focuses on the core workflow: a basic keyboard, an f(x) scientific panel, DEG / RAD trigonometric input, in-keyboard history, and a companion app for setup guidance, basic settings, and About. It does not include accounts, cloud sync, or online computation. Settings stay on the device.

A minimalist cross-platform Markdown note-taking app designed to streamline your workflow and sync seamlessly across your devices, no server required. Stay organised, stay focused and keep your notes private. FEATURES • Local Sync. Paired devices automatically synchronise notes via your local network, no server or account is required. If a conflict occurs, both versions are kept and the older file is moved to the trash with a [conflicted] label. • Plain Markdown files. Each note is saved as a standard Markdown .md file in regular folders. Your data belongs entirely to you, meaning you can back it up, use other editors, or track it with Git. • Raw Markdown styling. Beautiful raw Markdown rendering of headings, bold text, italic text, lists, horizontal lines, quotes, code and code blocks, links, and tables. • Sidebar. Easily organise your notes. You can drag and drop folders, select multiple files at once, and rename items. Deleted notes can be recovered until the trash is manually emptied. • Command Palette & Search. Navigate the app instantly using a central command palette. Run full-text searches across your open note or across all of them. • Customisation & Settings. Choose from four beautiful themes and start customising your experience. All your configurations are saved in a settings.toml file, making them easy to back up and export. • Intuitive Touch Gestures. Navigate fluidly on mobile devices. Swipe from the left to open the sidebar, from the right to access the command palette, press and hold to open context menus and tap with three fingers in the editor for a context-menu. OPEN SOURCE Minoo is free and open source under the MIT licence. Read the code, file an issue, or build it yourself: https://github.com/ScepticDope/Minoo
