Mobile apps
for business operations

Production-ready mobile applications for invoicing, document scanning, and inventory management. Cross-platform: Android and iOS. Offline-first, privacy-focused.

Our mobile apps

Finished products we designed, built, and shipped ourselves. Each one is also a live demo of what we can build for you.

What we build to order

The apps above are our own. Custom work is the other half: we take a mobile app from a written spec and concept to store release, and support it after launch. You get a finished product in the stores, not a codebase.

Invoicing and document apps

Create documents on the phone, export clean PDFs, keep the data on the device. Fyntoo Bill and Fyntoo Scan are live in this exact category: invoicing and receipt scanning for small businesses.

Field service and geo apps

Work orders on a map, routes for the day, geo check-in, photos and client signatures as proof of work. Fyntoo Field is built on exactly this stack.

Inventory and barcode apps

Barcode scanning, stock movements, thresholds and reports, offline mode for warehouses with no signal. InvoStock shows the pattern working.

Voice and AI-assisted apps

Dictate instead of typing: voice notes become structured records. Yarna turns a realtor's thirty-second voice note into a filled-in client card.

Offline-first by default

Our specialty: apps that keep working in basements, warehouses and countryside, and keep the data on the device. Sync and cloud are added when the business needs them, not before.

We do not bill by the hour. You approve a fixed scope and a fixed price, and you get a finished product on the agreed date. Once the spec is signed off, there are no surprises.
