App development cost calculator.
An app development cost calculator for MVPs and AI agents. Answer six questions to see the size of your build, a starting price and a rough timeline.

What drives development cost. Most of the price is engineers’ time, so cost follows the same drivers as the timeline.
- 01
Scope of the core flow
The number of features and screens on the one journey that must work. Cutting to the core flow is the biggest saving.
- 02
Platforms
Web, iOS and Android each add build and test work. Many first versions launch on one platform.
- 03
Integrations
Every system the product or agent talks to, such as payments, CRM or core banking, adds build and testing time.
- 04
Compliance
KYC, health data or payment rules add design, review and audit work from day one, not as a retrofit.
- 05
Risk of actions
For AI agents: answering questions is cheapest. Actions that need approvals and audit trails cost more.
- 06
Testing rounds
Agents are tested against real cases. More rounds, or requirements that keep moving, raise the price.
Project size by type. How projects are shaped, from a lean first version to a larger build.
| Project | Range | What it looks like | Timeline |
|---|---|---|---|
| MVP or app | Lower end | A narrow product: one platform and one core flow. | about 5 to 8 weeks |
| Mid range | More features, a second role or a couple of integrations. | about 8 to 14 weeks | |
| Upper end | Several roles, more than one platform, integrations or compliance. | about 14 to 20 weeks | |
| AI agent | Starting range | One agent, one clear job, a small number of tools, light testing. | a few weeks |
| Mid range | An agent over your documents plus actions in one or two systems, with approval steps. | about 4 to 8 weeks | |
| Upper range | Several tools and systems, audit trails and many test rounds. | about 8 weeks or more |
Real builds at both ends of the range. Delivered projects, and the time each one took.
Cost questions.
How much does app development cost?
With us, projects start from USD 10,000 and the price rises as the scope grows. Where a project lands depends on scope, platforms, integrations, compliance and testing.
How accurate is this calculator?
It shows where your project sits, from a lean first version to a larger build, based on the main cost drivers. It is a guide to how projects are shaped, not a quote. A short call or a written scope gives a fixed price.
What is not included in the estimate?
Running costs such as hosting, model usage and third-party services, and any retainer for support after launch. These depend on real usage and are priced separately.
How long does development take?
Our delivered builds range from five weeks (stablecoin payment rails) to 20 weeks (a compliant crypto exchange). A focused first AI agent can take a few weeks.
Can we agree a fixed price?
Yes. We agree a fixed scope for each stage, with a working version at the end of it, so cost stays predictable.
Should we start smaller?
Usually, yes. One agent doing one job well, or one platform with one core flow, teaches you more than a large build. A proof of concept shows what your case needs.
How do I keep development cost down?
Cut features until the core flow is the only thing left, reuse proven services for payments, login and messaging, and keep the first version on one platform.
Can you sign an NDA before we share details?
Yes. Tick the NDA option in the contact form and we send one before the first conversation.
