@tailfins was kind enough to link to a few things to download to use the app outside of Apple and Google. Was easy for me, but I want to make it easier for my friends here that may be interested, so I can get you guys over there!

First thing you will likely want to do, is make it so that your phone will accept installing 3rd party applications outside of the markets. Hopefully these instructions are up to date enough to help.

(If you know things already, pass all this and go to the bottom where the download links are)

How to accept the install of 3rd party apps on Apple Iphones:

Manually install and trust an enterprise app

When you first open an enterprise app that you've manually installed, you see a notification that the developer of the app isn't trusted on your device. You can dismiss this message, but then you can't open the app.



After you dismiss this message, you can establish trust for the app developer. Tap Settings > General > Profiles or Profiles & Device Management. Under the "Enterprise App" heading, you see a profile for the developer.



Tap the name of the developer profile under the Enterprise App heading to establish trust for this developer.



Then you see a prompt to confirm your choice. After you trust this profile, you can manually install other apps from the same developer and open them immediately. This developer remains trusted until you use the Delete App button to remove all apps from the developer.



You must be connected to the Internet to verify the app developer's certificate when establishing trust. If you're behind a firewall, make sure that it's configured to allow connections to https://ppq.apple.com. If you aren't connected to the Internet when you trust an app, the device displays "Not Verified" instead. To use the app, connect to the Internet and tap the Verify App button.

After you verify an app for the first time, your iPhone, iPad, or iPod touch must reverify the app developer's certificate periodically to maintain trust. If you can't reverify, you may see a message that verification will expire soon. To maintain trust, connect your device to the Internet, then tap the Verify App button or launch the app.

How to accept the install of 3rd party apps on Android

Install unknown apps permission option is located in the setting app. So…

At first, open the android default Setting app.
Then click on the new Apps and Notifications menu.
Now click the Special Access button. (follow below screenshot) (Gotta click on the 3 dot menu and then click special access on my Samsung phone)



Now click Install unknown apps. Then you can see your all app list.



Now click on the app you want to allow third party apps.
Now you can see a new screen like the below screenshot.



Now click the Allow from this source button.

Now your install third party app option is enabled. So, go back to your app and tap on an APK file. Now you can install any android apps on your phone.

This is a direct download here. It's from the Google App store, so it works. It's an APK file installer, or at least the one I use:

https://play.google.com/store/apps/d...aller&hl=en_US

And rather than jump through hoops, this you can download here to your phone, then use the APK installer to install it (MAKE SURE you note where you download it to, wherever your download folder may be)
