Is there a phone app

Yes. Jupiter Signup is on Google Play for Android phones. Sign in with the same account you use on the website and your forms are all there.

What the app does

• Build a form by describing it, and change it by chatting.
• Send you a notification for every new sign-up.
• Show who's coming, who said no, and the headcount.
• Share your form's link by text or email.

Connecting Stripe and changing your plan happen on the website.

iPhone

The iPhone app isn't in the App Store yet. Until it is, jupitersignup.com works in Safari on your iPhone.

The people signing up never need the app. They use your form's link from any phone or computer.
