Variables

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 you—sleep, mood, coffee, pages read, workouts, anything—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
