Enables precise hive management: Knowing exactly when brood reaches key stages (egg → larva → capped → emergence) helps with swarm prevention, requeening, and colony health checks.

Helps with queen rearing: Timing is critical. An app could notify when to move queen cells, when virgins should emerge, and when to expect mating flights.

Aids disease control: Brood cycle knowledge helps detect issues like brood breaks, chalkbrood, or varroa infestation timing.

Provides beginner education: New beekeepers often struggle to remember the differences between the timelines of worker, drone, and queen bees. A visual timeline would be a great teaching tool.

Helps with record-keeping: Logging “egg laid (or seen)” dates per hive could give reminders like “expected worker emergence on X date.”

Honey Bee Development Timelines (approx.)
- Worker: 21 days (3 egg, 6 larva, 12 pupa)
- Drone: 24 days (3 egg, 6.5 larva, 14.5 pupa)
- Queen: 16 days (3 egg, 5 larva, 8 pupa)

Benefits:
- Queen rearers (precision timing is everything).
- Hobby beekeepers (reminders of when to check hives).
- Clubs/mentors (as a teaching resource).
- Commercial operations (batch rearing, swarm control planning).
