What every app build includes

All of this is part of a standard build, not an upsell found halfway through.

  • One build, both platformsiPhone and Android from a single codebase, so you are not paying twice or waiting twice.
  • Published under your nameYour business owns the App Store and Google Play listings, the branding, and the customer relationship.
  • A web version tooMost builds include a browser version so customers who will not install an app can still use it.
  • Push notificationsReach customers about bookings, orders and offers directly on their phone.
  • Accounts and paymentsCustomer logins and card payments wired up properly, not bolted on later.
  • Store submission handledReview guidelines, privacy labels, screenshots, and the resubmissions when Apple asks for changes.

What a small business app costs

Setup on a straightforward app starts around $100; a full build with accounts, payments and integrations typically lands under $1,000.

App development used to cost tens of thousands of dollars because a shop put several people on it for months. We build with AI tools, so the same work takes a fraction of the time. After launch it is $20 to $60 a month to host, update, support and keep in the stores.

Your exact number depends on what the app has to do. You get it in writing before you commit, and it does not move afterward.

Before you build an app

We would rather talk you out of the wrong project than sell you one.

  • An app is not always the answerIf customers interact with you a few times a year, a good mobile website usually beats an app they will delete. We will say so.
  • The stores charge their own feesApple and Google each charge a developer account fee, and take a cut of in-app purchases. Those are theirs, not ours, and we tell you the numbers up front.
  • Reviews take timeApp Store review is outside anyone's control. We build fast, but the store queue is the store queue.

Tell us what the app needs to do

Describe it in plain language. You get a written scope and a flat price back, and a straight answer if a website would serve your customers better.
