The best festival planner app for UK weekends does three jobs: builds a timetable, flags clashes, and remembers what you saw when you get home.
Alert-only apps and PDF grids cover the first job poorly. Standalone clashfinder sites often skip the diary. Radar Pro Clashfinder plans Glastonbury, Reading & Leeds, Download, TRNSMT, Latitude, and boutique weekends — then logs them beside your year-round club gigs.
Look for reminders before your next set, crew tags for who you went with, and Concert Wrapped so festival weekends count in your year-in-review stats.
Free Radar still lets you log festivals; clash planning and reminders need Pro. Start free, upgrade when lineup season hits.
