Independent software studio

We build apps and websites, and make sure they're safe.

Nightsafe Software designs and ships iOS and Android apps and fast websites, and tests software for security flaws before attackers find them. Our own apps are live on the App Store, so we know what it takes from idea to launch.

Services

Three things, done properly.

Mobile apps

Native iPhone and iPad apps in Swift, and Android apps in Kotlin, from first sketch to App Store approval.

  • Design, build and App Store / Google Play launch
  • Subscriptions and in-app purchases
  • Firebase backends, push notifications, sign-in
  • AI features: image, video and chat

Websites

Fast, clean websites for businesses and apps that look right on every phone and load in a blink.

  • Business sites and app landing pages
  • Domain, DNS, hosting and email set up for you
  • Search basics: titles, previews, sitemaps
  • Privacy policy and support pages for app stores

Security audits

We look at your app the way an attacker would, then tell you exactly what to fix, in plain language.

  • Source code review of apps, APIs and backends
  • Login, permissions and payment logic testing
  • Firebase and cloud configuration review
  • Written report with proof and fixes, plus a retest

Our apps

We ship our own products, too.

Everything below was designed, built and launched in-house: the app, the server, the payments and the App Store listing.

How it works

Simple, from first message to launch.

  1. 1

    Talk

    Tell us what you need. We'll ask the right questions and tell you honestly what it takes.

  2. 2

    Plan and quote

    A clear written scope, timeline and fixed price before any work starts. No surprises.

  3. 3

    Build

    Regular updates and test builds you can try on your own phone as we go.

  4. 4

    Launch and support

    We handle App Store review, hosting and go-live, and stay around for fixes after.

Security audits only cover systems you own or have written permission to test. We agree on the scope in writing first.
