Yes, after the app has been opened at least once with a connection. SonicPlanner caches its app shell and festival data locally so it is much more usable once signal gets bad.
Yes, but only in your own browser. SonicPlanner saves your picks and ratings locally on your device so the app can remember your lineup.
Your lineup data is stored in your browser's local storage on that device. It is not stored in a server-side account for this version of the app.
No. Because your data is stored locally in the browser, it stays on the device and browser where you made the selections.
It should work much better offline if you open the app before arriving and let it load first. That gives the browser a chance to cache the schedule pages and images ahead of time.
If two or more selected bands overlap, SonicPlanner keeps the highest-rated band in the main itinerary. Lower-rated overlapping bands are shown as backups for that time slot.
“Must-see” means you rated a band 5.0 out of 5. Only 5-star selections get that label.
