Build an iPhone app that adds events to your calendar

Borel builds iPhone apps that put events straight into the iPhone's Calendar. Describe what people plan in your app, and Borel writes it in Swift with Apple's EventKit, asking only to add events, so the app never needs to read the rest of someone's calendar. Each event lands with its title, time and notes.

Ideas

What you can build with calendar

A few apps people make with it. Describe yours in your own words.

  • A study planner

    Plan study sessions and add each one to your calendar.

  • A class timetable

    The term's lessons, added to your calendar in one go.

  • A fixtures list

    Your team's games in your calendar, with the ground in the notes.

  • A booking keeper

    Appointments and reservations, each saved as an event.

  • A shift planner

    Your work shifts for the month, each one in your calendar.

Try it

A prompt to start from

Copy it, or start with it and change it to fit your idea.

The prompt
“A study planner: I plan study sessions by subject and add each one to my calendar with a reminder.”

From words to your iPhone

Three steps, no code

  • 1

    Describe it

    Say what the app does in plain words, or start from the prompt above. No code, and no Mac.

  • 2

    Watch it build

    Borel writes the Swift, compiles it with Xcode on its own Mac and opens it in the iOS Simulator, streamed into your browser.

  • 3

    Put it on your iPhone

    Borel Companion installs it over a cable the first time, then over Wi-Fi, and while it runs it puts each new version on by itself.

How Borel handles it

Written in Swift, with Apple's own frameworks

What Borel takes care of for you, so the feature works the way iPhone owners expect.

  • Add-only access

    The app asks only to add events, Apple's lighter permission, with a sentence Borel writes for your app.

  • Apple's event screen

    Or the app opens Apple's own event editor, filled in, for people to check and save.

  • Reading, when an app needs it

    An app that shows your existing events asks for full access instead, with its own sentence saying why.

Try it in the iOS Simulator in your browser while you build, then on your iPhone with Borel Companion, where events go into your own calendar.

Your Apple ID

Works with a free Apple ID

Yes. Borel Companion puts the app on your own iPhone with a free Apple ID, which keeps up to 3 of your apps there, and Companion renews them every 7 days for you.

Frequently asked questions
