Apps built by the same founder who builds your site.
SEMPITE designs and builds Android apps, installable iPhone web apps, games and internal tools for small businesses and personal brands, from scoping to a signed release you can hand to customers.
Most small businesses never get an app because agencies price them like enterprise projects. SEMPITE builds lean: one founder-led team, one codebase that runs on Android, iPhone and the web, and hosting on our own infrastructure when the app needs a backend.
Your customers live on their phones. Your business mostly does not.
A booking flow, a loyalty card, a field tool for your team or a branded game all work better as an app than as another tab. The usual quote for a custom app is out of reach for a small business, so the idea stays on the list. We build the smallest version that does the job well, then grow it with you.
One codebase, every screen.

Custom quote after a scoping call
Scope, prototype, build, release.
We start by agreeing on the one job the app has to do and put a written quote on it. You get a playable prototype early, so decisions are made on something you can hold. Then we build, test on real devices, sign the release and publish it where your customers are: a download page on your site, the home screen of their iPhone, or Google Play.
Play something we built.
Hold The Base is a SEMPITE game: an isometric tower defense with ten maps, a medieval kingdom, a post-apocalyptic wasteland, a city bank heist and a limited-edition Halloween night. It runs as a signed Android app, installs on iPhone from Safari and plays in any browser, all from one codebase.
Straight answers on building an app.
What kinds of apps do you build?
Android apps, installable web apps that work on iPhone and Android, games, and internal tools such as client portals, dashboards and automations. If it runs on a phone or in a browser, we can scope it.
Can you build for iPhone and Android?
Yes. Android apps ship as an installable APK or through Google Play. For iPhone we build installable web apps that go on the home screen, run full screen and work offline. Native App Store releases are scoped per project because they need an Apple Developer account.
How much does an app cost?
It depends on scope. Every app starts with a scoping conversation and a written quote before any build work begins, so you know the price before we write a line of code.
Can I see something you have built?
Yes. Hold The Base is a SEMPITE game you can download for Android or install on iPhone for free. It was designed, built, signed and released entirely in house.
Can you host the backend too?
Yes. Apps that need a server, a database or AI features can run on SEMPITE's private infrastructure, the same servers that host client websites, so there is no separate host to manage.
Tell us the one job your app should do.
A short conversation is enough to know whether an app is the right move and what it would take. No lock-in, ever.
