Since/Until is an iOS and macOS app for tracking important dates. Count the time since past events or count down to future ones, with smart formatting that shows the most readable combination of years, months, and days. Colour-code entries for visual organisation and link them to calendar events for automatic date syncing. Home screen widgets include a moon phase display, single date gradients, and multi-date lists in several sizes. A built-in moon phase tracker shows the current phase with illumination percentage. Data syncs across devices via iCloud. The app is under 1 MB.
