About

Variables

Read full description

Variables is a simple way to track anything and actually understand it. Most habit trackers ask "did you succeed?" This one just asks "what happened?" Log whatever matters to youβ€”sleep, mood, coffee, pages read, workouts, anythingβ€”and look for patterns later. How it works Create variables with flexible data types: numbers, durations, categories, yes/no, or freeform notes. Log values whenever you remember. No streaks to break, no guilt when you miss a day. A low number is just data, not a failure. Over time, you build up a picture of what your life actually looks like. Then you can start asking questions. Voice logging Tap the microphone and say something like "slept 7 hours, mood good, read 30 pages." The app parses it automatically and logs each value to the right variable. No typing required. Ask questions in plain English "Do I sleep better when I exercise?" "What's my average mood on Mondays?" "How much coffee did I drink last week?" The app translates your question into a database query and gives you the answer. Features - Flexible variable types: numbers, durations, enums, booleans, text - Voice input with automatic parsing - Natural language queries (or write SQL directly if you prefer) - Goal tracking with weekly targets - Analytics dashboard with trends and streaks - Calendar view of your logged data - Dark mode - API access for custom integrations - Self-hostable if you want full control of your data

Instead of lists and folders, you get a zoomable grid where you can place notes wherever they feel right - cluster related ideas together, spread a project across the canvas, or keep a corner just for quick thoughts. FEATURES - Large canvas β€” pan and zoom freely across a grid canvas - Place notes anywhere β€” long press anywhere on the canvas to drop a note - Rich notes β€” add a title, body text, color, images, videos, and PDF attachments - Pin notes β€” lock important notes in place so they don't move while you pan - Search β€” find any note instantly by title or content - Export & import β€” back up all your notes as a single JSON file - Fully offline β€” everything stays on your device, nothing is sent anywhere DESIGNED FOR FOCUS No accounts. No subscriptions. No ads. No cloud sync. Just you and your canvas. Grid Notes is built for people who think spatially - writers mapping out a story, developers tracking ideas across a project, students connecting concepts, or anyone who finds flat lists too limiting. PRIVACY All your notes, images, and files are stored locally on your device. Grid Notes does not collect any personal data and has no internet connection.
