Ask "what does an app cost?" and you'll get answers from $500 to $500,000, which is another way of getting no answer at all.
I build custom apps and web tools for small businesses, so let me do the thing agencies hate doing and put real numbers in writing. These are honest ranges for working with a small studio like mine in 2026, along with the reason the math looks nothing like it did a few years ago.
First, why the old numbers are dead
The quotes you remember from 2019 came from a world where every screen, every form, and every database table was typed out by hand, by a team, over months. Development was priced like custom furniture because that's what it was.
AI-assisted development changed the economics at the foundation. An experienced developer with modern tools now produces in a day what used to take a week. Not lower quality, the same code, reviewed and tested, just without the slow parts. I ship in days what would have been a quarter-long engagement. When you're paying for time, and the time drops by that much, the price follows.
The catch: experience matters more now, not less. The tools amplify whoever is holding them. Someone who doesn't understand security, data, and edge cases just produces bad software faster.
The honest ranges
A simple internal tool: roughly $1,500 to $5,000. One job, done well. A quoting calculator, a job tracker, a form that feeds a schedule, a dashboard showing the numbers you currently dig for. One or two screens, a database, login. Days, not months.
A customer-facing web app: roughly $5,000 to $15,000. Customers log in, book, pay, or track something. More polish, more security surface, payments integration, email notifications. A few weeks including revisions.
A mobile app in the app stores: roughly $8,000 to $25,000. Everything above plus the app store gauntlet: Apple review, Android review, store listings, updates. Modern frameworks let one codebase serve both platforms, which is the only reason the number starts with an 8 and not a 40.
Ongoing costs, because there are always ongoing costs: hosting and services typically run $20 to $100 a month for small-scale apps. Budget something for maintenance too. Software is a living thing. Anyone quoting you zero ongoing cost is hiding it somewhere.
What moves you inside those ranges
Three things, mostly. Number of user types (customers plus staff plus admin is three apps wearing a trench coat). Integrations, because talking to your accounting software or a payment provider is where budgets quietly grow. And ambiguity, the expensive one. "I'll know it when I see it" costs multiples of a clear one-page description of what the thing should do.
How to not get burned
Get a fixed quote against a written scope, not an hourly estimate against a vibe. Start with the smallest version that solves the real problem, then grow it once it's earning its keep. And ask any developer what happens after launch. The answer tells you whether you're buying software or an abandonment.
The bottom line
Custom software finally fits small business budgets, and most owners are still pricing it off memories from a different era. If there's a process in your business you've been thinking about automating, describe it to me and I'll give you a straight number.
