Short answer: you have three realistic options. You can build it yourself with an AI app builder, which is cheap to try but leaves you responsible for fixing and securing it. You can hire a developer or agency, which gets you skilled help but usually means a large bill up front and another one for maintenance. Or you can pay one monthly fee to have it built and looked after, which spreads the cost and puts someone else in charge of keeping it working. The right choice depends on how much time you have, how much you can pay up front, and how much it matters if the app breaks.
Before you pick, it helps to know what "getting an app built" really involves.
Step zero: write the idea down
Whichever route you choose, you will save time and money if you can answer these on one page:
- Who is it for? One sentence about the person who will use it.
- What is the one thing they do in it? Not ten features, the main one.
- Do they need an account? Logging in means storing personal data, which means security work.
- Does money change hands inside the app? Payments add work, testing and rules from the payment provider.
- Phone, computer or both? A web app works on any phone from a link. A store app needs a store listing.
This page is what every builder, developer or agency will ask you for first. Most first versions should do one thing well, not everything at once.
Option 1: Build it yourself with an AI app builder
Tools such as Lovable, Bolt and Replit turn written instructions into a working app. You describe what you want, the tool writes the code and shows you a preview.
What is good:
- Cheap to start, and you can try an idea in an afternoon.
- You see something on screen very quickly, which helps you think.
What to watch for:
- You become the engineer. When the tool gets something wrong, you need to describe the problem well enough for it to fix it, or read the code yourself. Many people get stuck in a loop where each fix breaks something else.
- Security is your job. Lovable's own documentation says its security tools "cannot guarantee complete security" and that you are "responsible for ensuring that your app meets the security requirements appropriate for its use case" (Lovable docs). Our guide Is Lovable secure? explains the gaps that most often leak data.
- Publishing and running it is still work. For example, Lovable's docs say changes are not pushed live automatically and you have to republish (Lovable docs). Someone has to watch the live app, fix bugs and answer users.
Best for: testing an idea, or a small tool for yourself.
Option 2: Hire a developer or an agency
You explain the idea, they quote and build it.
What is good:
- Skilled people make the technical decisions.
- You get a professional result if you choose well.
What to watch for:
- The bill comes before the users. You pay for the build before you know whether anyone wants the app.
- The quote often ends at launch. Ask what happens when it breaks in month three. Cleveroad, an app development company, cites the Consortium for Information & Software Quality (CISQ) putting yearly maintenance for small and medium business products at 15 to 20% of the original development cost every year (Cleveroad). That is on top of the build.
- Store fees are extra. If you want your app in the stores, Google Play charges a US$25 one-time fee (Google Play Console Help) and Apple charges US$99 a year (Apple Developer).
Best for: people with a budget for the build and a plan for paying maintenance afterwards.
If you go this way, get a written list of every screen and feature before work starts, and agree in writing who fixes bugs after launch and what it costs.
