| Guest task | Website check | App check |
|---|---|---|
| Read the schedule | Can it open from the invitation link? | Is installation required to read it? |
| RSVP | Does the browser save the correct event replies? | Does the app use the same guest identity and answers? |
| Travel directions | Are addresses and operator links easy to copy? | Does it add something beyond a map link? |
| Get updates | How do guests learn that something changed? | Are notifications supported and enabled? |
| Limited connectivity | What information can the guest save beforehand? | Which functions actually work offline? |
An app icon does not prove offline access or reliable notifications. A website that looks like an app does not prove that data will be saved without a connection. Test the functions you rely on and keep another way to reach guests when plans change.
