For hobbyists

Build the app that's been rattling around in your head.

The wedding RSVP. The D&D character sheet. The shared grocery list. The thing your friend group keeps asking for. You don't need a startup to make a real app. You just need an afternoon.

Build something silly See how it works

You've had the idea for years.

You've described it to friends at dinner. You've drafted it in your Notes app. You'd build it yourself if it didn't mean three weeks of evenings learning a framework.

So it stays in your head. Or it lives as a half-finished spreadsheet only you can navigate. Envelope is the version of you that actually finishes the project. Tell it what you want and have a working app on your phone before bed.

Things people actually build

None of these will go viral. All of them are someone's favorite app on their phone.

Apps for one person (you)

A reading tracker. A workout log shaped exactly how you like. A pill reminder for your cat. The little tool you wish existed.

Apps for your people

A wedding RSVP. A D&D character sheet for your party. A meal-planning app for your roommate situation. Things only your group needs.

Apps as gifts

A countdown to your friend's wedding. A trivia app about your dad. A recipe app of your grandma's handwritten cards. The most personal thing you can give someone.

From idea to home screen

You've been talking about this app for months. It's faster to build it than to explain it again.

Step 1
Describe what you want
Tell Envelope the thing. 'A bingo card maker for my book club.' 'A list of every concert I've ever been to.' Plain English, no jargon.
Step 2
Make it weird and yours
Pick colors that make you happy. Use an icon of your cat. Add the running joke. This isn't for a customer, it's for you.
Step 3
Put it on your home screen
Tap the link, add to home screen, done. Now the app you've been thinking about lives next to your bank and your texts.

Build the thing

Less than a movie ticket. Yours forever.

Questions hobbyists ask

Good. The best personal apps are. A tracker for how many times your cat knocks things off the counter. A random picker for whose turn it is to text first. None of these are going to change the world, and none of them need to. Build it. You'll smile every time you open it.

Build the app you've been describing at dinner.

It takes an afternoon. It's free to start. It'll make you smile.
