Android and iOS apps
One codebase built with Flutter, so your app looks and feels at home on both platforms, and new features reach everyone at the same time.
Software studio · United Kingdom
We build thoughtful apps for Android and iOS.
IONCODEX designs, builds and publishes mobile apps that people enjoy using every day, with their privacy built in from the first line of code.
What we do
From the first sketch to the App Store and Google Play, we take care of the whole journey.
Privacy by design
Personal data stays on the user's device wherever possible, and anything shared is kept to the minimum, in line with UK GDPR.
From idea to launch
Design, development, testing, servers and store releases, with automatic builds and deployments so updates ship safely and quickly.
Our apps
Products we design and build ourselves.
MoonCycle
Period and cycle tracking that keeps what you log on your own phone, with an optional partner side that helps couples understand and support each other, only ever sharing what she chooses.
Coming soon to the App Store and Google Play · mooncycle.fit
