## Custom app cost estimator

Choose what your app should do and get an estimated range in a minute.
It is an estimate, not a quote. Discovery turns it into a fixed price in writing.

**Short answer.** A custom app from Sarasoris starts with Discovery at $1,500 and a first module at $4,000 to $10,000. Each further module adds $4,000 to $12,000 and each connection to another system $2,000 to $6,000. Most full projects land between $8,000 and $80,000.

### Estimator

### The ranges it uses

| Item | Range |
|---|---|
| Discovery | $1,500, fixed |
| First module | $4,000 to $10,000 |
| Each additional module | $4,000 to $12,000 |
| Each connection to another system | $2,000 to $6,000 |
| App Store and Google Play app, on top of web | $3,000 to $8,000 |
| Works offline | $2,000 to $5,000 |
| Each kind of user beyond two | $1,000 to $3,000 |
| Moving old data in | $1,000 to $4,000 |

Where in each range you land depends on how many screens and rules the piece needs, which Discovery works out. Hosting, usually $50 to $200 a month, is paid directly to the provider.

### Example

Two areas (scheduling and reporting), one connection to a donor system, and an App Store app: $1,500 + $8,000 to $22,000 + $2,000 to $6,000 + $3,000 to $8,000, so about $14,500 to $37,500. Starting with just the first module would be $1,500 for Discovery and $4,000 to $10,000 for the module.

### Questions

#### Is the estimate a quote?

No. It shows the likely range. Discovery ends with a fixed price in writing for exactly what you need.

#### Why such wide ranges?

Because “inventory” can mean one screen or forty. Discovery narrows it to one number.

#### Do we have to build everything at once?

No. Most clients start with one module. See [what a custom app costs](https://sarasoris.com/custom-app-cost) and a [sample Discovery plan](https://sarasoris.com/sample-discovery-plan).
