An install prompt shown on arrival asks for commitment before the visitor has experienced any value. The brief should connect prompting to a useful moment and acknowledge that browser support and installation flows differ.
Define eligibility and timing
Record the supported browsers, technical install criteria, and product signal that makes the invitation relevant. Good signals may include a completed task or repeated use. Never block the main journey while waiting for an install decision.
Respect dismissal
Specify how long a rejection suppresses the custom prompt and where installation remains discoverable later. Avoid repeated overlays, misleading urgency, or language that suggests installation is required when the website still works.
Set accurate expectations
- Name the benefit that is actually available.
- Explain offline behavior without claiming every feature works offline.
- Define updates and stale-content handling.
- Provide an uninstall or reset help route.
- Measure exposure, acceptance, dismissal, and post-install use separately.
Test the real lifecycle
Check first eligibility, acceptance, dismissal, refresh, browser-managed installation, launch from the installed icon, offline states, and an application update. Record unsupported environments as expected outcomes.
