Privacy-first iPhone apps

Simple tools for
everyday phone problems.

Spam calls, cluttered storage, a fading battery, and confusing settings. Mio Software makes small, focused apps that fix real phone headaches — and keep your data on your device.

🔒

On-device by design

Our apps do their work right on your iPhone. We don't send your messages, calls, or personal content to any server.

Simple and focused

No clutter and no jargon. Each app does one useful thing well, so anyone can pick it up in a minute.

📱

Built for real people

Designed with everyday phone users in mind — the folks who just want their phone to work and leave them alone.

About Mio Software

Mio Software LLC is a company building a family of small, dependable iPhone apps.

Every day, people deal with the same frustrations: relentless spam calls and texts, storage that's always full, batteries that fade, and settings that feel impossible. These aren't dramatic problems — they're the small, daily kind that make a phone feel like a chore.

Mio Software exists to quietly fix those. We build focused apps that each solve one common problem, with a clean design and a strong respect for your privacy. Our first app is a spam call and text blocker that runs entirely on your device, and more tools are on the way.

Where we are today

Mio Software is a newly formed company, and we're building in the open. Here's what we're working on and what's next.

Spam Blocker Flagship In development

Automatically screens unknown calls and text messages and sorts them into clear categories — Junk, Promo, and Transaction — with a color-coded log so you always know what got filtered and why. It never touches messages from your contacts, and it never sends your content anywhere.
