The cost of building an app with AI is mainly the AI builder subscription (many start with a free plan, then paid plans), plus relatively small running costs: your domain, payment gateway fees per transaction, App Store and Google Play developer accounts if you want a mobile app, SMS and WhatsApp messages, and AI model usage if your app has AI features. The biggest line is often not technology but your time and marketing. The total is usually a small fraction of what an agency quotes for the same first version.

How much does it cost to build an app with AI?
Building an app with AI costs far less than traditional development, because the most expensive part, developer hours, is handled by an AI agent that writes, tests and deploys the code. But it is not zero. You pay for the AI builder subscription (most tools start with a free plan, then paid plans), running costs such as your domain, payment fees and messaging, app store fees if you publish a mobile app, and possibly AI model usage if your app's own features use AI. On top of that come your time and marketing.
This guide does not quote fixed figures, because tool and service prices change and vary with volume and country. Instead it gives you the complete list of cost lines and what pushes each one up or down, so you can calculate your own budget. For a quick estimate, try the app cost calculator, and for Fanann's plans see the pricing page.
AI has cut the cost of writing code. It has not cut the cost of choosing what is worth writing.
Every cost line for your app
| Cost line | When you pay | What drives it |
|---|---|---|
| AI builder subscription | Monthly or yearly, or free at first | Plan, number of projects, usage, launch features |
| Hosting and database | Often included in the plan or usage-based | Visitors, data volume and files |
| Domain | Yearly | Extension such as .com, .sa or .ae |
| Payment gateway fees | Per transaction | Payment method (mada, cards, Apple Pay, BNPL) and your gateway contract |
| App store developer accounts | Apple yearly, Google one-time | Whether you need a mobile app at all or a website is enough |
| OTP and WhatsApp messages | Per message or conversation | Number of sign-ins, confirmations and reminders |
| AI feature usage | By consumption (tokens) | Number and length of requests and the model used |
| Expert review (optional) | Once before launch or as needed | Data sensitivity and app complexity |
| Marketing | Ongoing | Channels: Snapchat, TikTok, Instagram, influencers |
Costs founders forget
- Refund and cancellation fees at the gateway, and failed cash-on-delivery orders.
- Customer service time on WhatsApp, especially during Ramadan and Eid.
- Photos and content: product and service images and page copy in Arabic and English.
- A commercial registration, licence or freelance document, depending on your activity and country.
- VAT and e-invoicing where they apply.
What pushes the cost up or down?
- Several sides: customer, driver, store and admin
- Live map tracking and real-time updates
- Custom integrations with legacy systems or government services
- A native mobile app published on both stores
- Sensitive data that needs security review and compliance
- Heavy use of AI features
- One clear user journey in the first version
- Starting with a responsive web app, mobile later
- Starting from a template close to your idea
- Describing data and roles precisely from the start
- Building and testing one feature at a time
- Postponing 'nice to have' features until after the first customers
For example, a booking app for a single salon is very different from a three-sided delivery app with live tracking. The first can be built and launched in days on a simple plan. The second needs more time, deeper testing, more messages and bigger hosting, even with AI. For the details, see how much does a delivery app cost in Saudi Arabia?.
AI builder, agency or freelancer?
A fair comparison is not about build price alone but about the full cost of the first year: building, changes, hosting, maintenance and the waiting time for every change. Here is a general, qualitative comparison:
| Criterion | AI app builder | Freelance developer | Software agency |
|---|---|---|---|
| First version cost | Usually lowest | Medium | Usually highest |
| Time to first version | Days | Weeks | Weeks to months |
| Cost of each change | Low: a conversation | Extra billable hours | Change request and new quote |
| Control | You lead directly | Depends on the freelancer's availability | Through a project manager |
| Best for | MVPs, internal tools, stores and bookings | Specific tasks or code review | Large, complex systems with strict requirements |
Many founders combine options: they build the first version with AI, then bring in a specialist for a security review or a hard integration. For more, read AI app builder vs a software agency and what really drives app cost in Saudi Arabia.
What can you do on a free plan?
Most AI builders, Fanann included, offer a free plan that is enough to try an idea: describe the app, see the interface, test the core journey and share it with a few customers. Paid plans usually bring higher usage limits, a custom domain and launch and operations features. Details differ between tools, so read each pricing page before you decide. More in build an app with AI for free: what you can really do.
- 1Build for free
A prototype of the core journey, tested on your own phone.
- 2Show it to customers
Five to ten people in your segment. Note what they understand and what confuses them.
- 3Launch when there is demand
Move to a paid plan and connect your domain and real payments once someone is ready to pay.
- 4Add mobile when needed
If customers ask for a store app, publish then and pay for the developer accounts.
The running cost of AI features inside your app
Keep two things apart: building the app with AI, and running AI features inside it, such as an assistant that answers customers or summarizes orders. The second is paid by usage, measured in tokens, the chunks of text the model reads and writes. Each customer question costs a little, but it adds up across thousands of users.
- Use a smaller, cheaper model for simple tasks and keep the strongest for hard ones.
- Limit answer length and the number of questions per user per day.
- Cache frequent answers instead of generating them again.
- Set a monthly spending cap and an alert in the model provider's dashboard.
The details are in what AI features cost to run: tokens, caching and limits.
Estimate your budget before you start
Before building, help me scope the project. My idea: a booking app for a women's home salon in Riyadh. Customers sign in with their phone number, choose a service, a stylist and a time, and pay a deposit with mada, Apple Pay or Tamara, with a WhatsApp reminder before the appointment and an admin panel for the salon. 1) Split the app into core features for the first version and features to postpone. 2) List the outside services I will need (payments, messaging, domain, app stores) and how each is charged: monthly or per transaction. 3) Recommend whether to start with a web app or a mobile app. Then build the first version only.
Try it in FanannYour next step: copy the cost lines from the table above, mark each as 'monthly', 'per transaction' or 'one-time', and add up your estimates for a full year. If you will publish to the stores, read what it costs to publish on the App Store and Google Play.
Key takeaways
- Cost is no longer just 'the price of development': it is a subscription, monthly running costs, your time and marketing.
- A free plan is enough to build and test a prototype; paid plans come with launch and growth.
- Payment fees, messages and AI usage grow with volume, so calculate them per order.
- Complex apps (multiple sides, live tracking, custom integrations) cost more time and money with any tool.
- Compare the full first-year cost, not the build cost alone, when weighing an AI builder against an agency.
