I have experienced plenty of crashes with android apps, so even though it is not officially recommended I think native applications from openrepos are very needed addition even though installing third party apps is somewhat discouraged for security reasons.

Aptoide (I have got malicious apps from aptoide, so be careful).Here is a short list of sources where I have found android app apks: Another option for sailfish x is the android app support, but finding safe apk files may be a task. The operating system is only one part of great smartphone experience, but usable applications provide the reasons to use any electronic device, so how can you get the best apps for your sailfish device? Of course there is the Jolla Store, but it has limited amount of apps. If you are totally lost in this likely new environment you may benefit from the manual (yes there is manual, but according to other posts on sailfish forums it is old, but the basics still apply): I got sailfish installed today and found out that getting started is really hard. (Before following this you should check the comment section for likely problems caused by bad instructions)
