Works out of the box
An iPhone app fits checking email, managing your day and finding contacts on the go.
Plan ahead: Email access is sensitive, so use Microsoft's secure sign-in and permissions rather than collecting email passwords, and check its approval requirements before launch.
Written by the checker for a first version. Paste it into Vibecode as is, or change it to make the app yours.
Build an iPhone app for people who want email, calendar and contacts in one simple place. Use three bottom tabs called Mail, Calendar and Contacts. Make Mail the main screen, showing sender names, subjects, previews and unread markers. Tapping a message opens it with a Reply button and a simple reply composer. Calendar should show an agenda with tappable event details. Contacts should have a search field and contact details where tapping an email address opens the composer. Use a clean white and blue style with clear text and dark mode. Start with realistic sample messages, events and contacts, with no real account connection yet.

You can build an inbox, a calendar and a contact list in one app. Start with Outlook accounts through Microsoft's API, then add other providers later. Connecting real accounts takes permission setup and testing.
Vibecode builds a first version from one prompt, and the checker would start with these parts: inbox with message reading and a simple reply composer; calendar agenda with event details; searchable contacts with tap-to-compose. Plan on a few weeks for a working first version with its real features.
Vibecode's first build is free for new accounts that sign up with Google or Apple on the web or the iPhone app, as the account's first project: one build of about 10 minutes with up to 3 features, on sample data. After that you need credits, from a paid plan or auto-reload. For your own version of Outlook, the checker lists these costs: Vibecode Plus ($20 a month); Apple Developer Program ($99 a year); API key for Microsoft Graph (that service's pricing).
Outlook provides an established email service backed by Microsoft's threat intelligence and email operations, not just an interface to another provider. A version you build yourself won't have these: Outlook.com sender reputation; Microsoft threat intelligence; Microsoft email operations team.
