What is the Relai Desktop App?

The Relai Desktop App is a self-custody Bitcoin wallet for Windows and macOS. It lets you buy Bitcoin, set up recurring auto-invest plans, track your portfolio in real time, and manage your savings — all from your desktop computer.

How do I download Relai for Windows or macOS?

Click the Download for Windows or Download for macOS button on this page. The installer will download automatically. Run it and follow the setup steps to start using Relai on your desktop.

Is Relai Desktop different from the Relai mobile app?

Yes. The Relai Desktop App is built specifically for larger screens, giving you a full portfolio overview, detailed transaction history, and a more complete view of your Bitcoin savings — all in one place on your PC or Mac.

Is the Relai Desktop App free?

Yes, downloading and using the Relai Desktop App is free. Standard Relai trading fees apply when buying or selling Bitcoin (from 0.9% with a referral code).

Relai offers a self-custodial wallet, meaning Relai never holds your Bitcoin. Your Bitcoin goes directly into a wallet only you can access, secured by a recovery phrase that only you know.

Best Bitcoin App

Support is truly amazing! Needed help a couple of times and within minutes you’re connected to a real person who guides you through it. Clean, user-friendly design — and the desktop app is just as polished. Great dev team from Switzerland. A clear recommendation from me.

Simple and Secure

After trying several apps to buy Bitcoin, Relai is by far the best for buying Bitcoin without any technical knowledge. The Bitcoin you buy goes straight into your own possession, since you manage your own private keys. Especially great for beginners.

Relai Delivers on Its Promise

It really doesn’t get easier than this. Download the app or open the desktop version, create a wallet, choose an amount, and transfer the funds. Done. The team is constantly working on improving the experience — and it shows.

Easy and Clear

Bitcoin-only, very easy to understand and well structured. The desktop app gives you an even better overview of your invested capital and value growth. Hot wallet with your own key management. Sending and receiving BTC is super simple on any device.

A Joy to Use

I’ve been using the app for quite a while now. It’s really smooth to use. You can even make instant purchases now. That’s why it gets the 5 stars.

Reliable and Well-Built

Reliable and well-built. Savings plans up to €100 are extremely affordable!

Really Love This App

A great solution for Bitcoin only. Plus a non-custodial wallet — perfect. Other than that, I really can’t relate to all the negative comments. A lot of users are just lost. Even my grandma can use this app without any issues. 😉

Never Had Any Issues

I’ve been a Relai customer since early 2022. Never had a single problem buying Bitcoin or sats. Top-notch.

The App Is Easy to Use

In my opinion, the best Bitcoin app in the German-speaking market in many ways. Thanks so much for your work! I’m truly enthusiastic and keep spreading the word to friends, family, and acquaintances. I’m happy to do it — especially because the referral bonus is set so fairly low. To me, that’s a sign of quality and a clear statement against pyramid schemes. Outstanding!
