You can check out all our available apps on the Mac App Store.
In case if an app has been removed from the Mac App Store, that you've downlaoded before, you can still install it by following the steps below:
- Sign in to the Mac App Store with the same AppleID that you've used when you've purchased the app
- Click the Purchased tab, where you'll see the list of all your earlier purchases
- Click the Install button on the right side
