Here's a NOSTR Setup on Android for those who want more control (requires above-average technical knowledge): a combo of Obtainium and Amber. I'll explain the 2 tips below:
(Oh, and a bonus tip for iPhone users: buy an Android. The Apple App Store has abusive practices that worsen every day, making life difficult for developers and users)
1. Use Obtainium to download app APKs.
Obtainium is an app that allows you to download and update open-source applications directly from developers, like on GitHub. This means you can get the latest versions quickly, without waiting for Google Play Store approval. It's useful for those who want the latest features or security fixes immediately.
This gives you direct and fast updates, without intermediaries. It brings the latest versions of apps to your device, ensuring you have immediate access to improvements and fixes.

Enable installations from unknown sources in Android settings to install.
Configure Obtainium: After installation, launch Obtainium. To add an application, copy the URL of the project of interest.
Add Applications in Obtainium: In Obtainium, tap the "+ (Add App)" button, paste the copied URL, select the necessary options, and tap on "Add". Obtainium will search for the correct version of the app for your phone and monitor the currently installed version.
2. Use Amber.
Amber is an application designed to better manage your private key. As you should know, in Nostr, we don't use a username and password. We use a public and private key. And if you enter your private key in a lot of places, there's a risk it could be compromised forever.
Amber allows you to securely store your Nostr private key in the application, which simplifies the authentication process across different Nostr clients and services without the need to repeatedly enter your private key.
Got it? The main advantage of Amber is convenience and security. It centralizes the management of your Nostr private key in one place, reducing the risk of exposure or loss of the key. With Amber, you can easily sign Nostr events using your stored private key, facilitating secure and efficient interaction with the Nostr ecosystem.
