App ideas to make money: 12 with a named buyer and a way to get paid

What makes an app idea able to make money?

Money comes from a person who has a problem that costs them time or money, and who has a budget for it. A student does not usually have one. A café owner paying a supplier every week, a landlord with ten flats, a coach with thirty clients, they do. That is why most ideas below sell to someone running a small business or a club, and not to the general public.

Three questions sort a paying idea from a free one. Who pays, and out of which budget? What do they pay for today, even if it is a spreadsheet or an hour of someone’s time? And how would they hand you money, as a monthly fee, a fee per use, or a share of what they earn? If you cannot answer all three in a sentence, you have an interesting app and not yet a business.

How do apps actually get paid?

Selling through an app store changes the sum. Apple’s Small Business Program lowers its commission to 15% for developers with up to USD 1 million in proceeds in the prior calendar year and for new developers, as of October 2026 (Apple). Google Play charges a service fee on sales through its billing system, and the rate depends on the market and program (Google Play service fees). For business tools sold on the web, you pick a payment provider instead and read its fee table.

A board idea shows the listing-fee model at its simplest: a premium advertising marketplace that lets businesses reserve limited ad slots, posted on the board. The hard part there is trust and traffic, since a slot is worth only what the page around it is worth.

Which app ideas could make money?

Prices in the entries are examples to test with real customers, not forecasts. Time estimates assume one person using an AI coding tool and cover the first working version.

How do you test whether people will pay before you build?

Charge before you build, in the smallest way you can. A conversation, a one-page description and a payment link will tell you more than a finished app nobody opens.

1. Name the buyer and the budget they would use. “Café owners, from the supplies budget” is a buyer; “everyone” is not.
2. Talk to ten of them. Ask what they do today, what it costs them, and when they last paid for something like it. Do not describe your app until the end.
3. Offer the manual version: you do the job by hand, in a spreadsheet, for two or three customers.
4. Put a price on it and ask for payment. A yes to “would you pay?” is cheap; a payment is not.
5. Build only the part that you did by hand more than twice.

Hi [name], I am building a small tool for [type of business] that [does one specific job, for example: turns supplier price lists into one reorder sheet].
Do you handle this today? How, and how long does it take you each [week/month]?
If it worked, would [price, for example USD 20 a month] be something you would pay? I would do the first month by hand for you so you can judge whether it helps.
No obligation, and thanks for any thoughts.

Where can you find more app ideas to build?

The board at Post your build ideas collects app ideas from people who will never build them. Browse all ideas, pick a category where you know the buyer, and every idea has a generated build prompt you can copy into Claude Code, Cursor or Lovable. If you have an idea you will never build, post it: it is free, needs no account, and publishing is permanent.
