WatchOS apps — when worth building

Apple Watch hit 200M users in 2025. The platform is real. Whether you need a Watch app is a different question.

Apps that benefit:

• Quick actions — fitness tracking, payments, smart home control. Watch shines for "5 second tasks".
• Notifications with action — taxi/food delivery tracking, calendar, messaging.
• Health and biometrics — heart rate, workout, sleep. The Watch reads sensors phones can't.
• Field workers — hands-free apps for nurses, mechanics, security.

Apps that should NOT be on Watch:

• Anything with text-heavy reading
• Apps where users spend >30 seconds at a time
• Apps that require sustained input (forms, editing)
• Visual media (video, large photos)

For most B2B SaaS — skip the Watch. For consumer apps with quick utility — worth shipping.
