Write UI Copy for an App

Write all UI copy for the following app screens and states:

App type: [e.g. productivity app / e-commerce / SaaS dashboard / mobile health app]
Brand voice: [e.g. friendly and casual / professional and precise / bold and direct]
Target user: [who uses this app]

Write copy for each of the following (adjust to what's relevant):
1. Onboarding screens (3–4 steps): headline + body + CTA for each
2. Empty states: when a section has no content yet (encouraging, not apologetic)
3. Error messages: 3 common errors — clear, human, and action-oriented
4. Success states: confirmation messages that feel good without being annoying
5. Tooltips: 3 feature explanations in under 15 words each
6. Destructive action confirmation: e.g. "Delete account?" dialogue
7. Push notification copy: 3 example notifications that feel personal, not spammy

Rules: No "Oops!" or "Uh oh." Be specific. Every word should earn its place.
