The problem

Pickup rules vary by type (and sometimes by week). In a busy routine, it’s easy to miss what goes out today.

You end up checking last-minute (night before / morning of).
Bi-weekly or custom repeats are hard to remember.
Time-zone changes or switching phones can throw reminders off.

The solution

Set it once per trash type — DingDong keeps your schedule, repeats, and multiple alerts together.

Weekly / bi-weekly / monthly / custom repeats + multiple alert times
Today/Tomorrow cards + monthly calendar for quick checks
Offline-first storage + local backup/restore
