There are many more alternative Android app stores out there, but most of them have small user bases. For developers, it’s always worth trying to widen the net and offer your apps in as many places as possible, but some of the smaller options might not be worth the time and effort. For users seeking apps, the apps available on the stores beyond those discussed above are limited. If a store doesn’t offer some unique hook to pull you in, then it’s tough to see why you’d bother.
In a world rife with messenger apps, WhatsApp is among the most successful, boasting an enormous and dedicated user base. Add to that an integrated web version that lets users take their chats to the desktop. Recently, this app was bolstered by encrypted messaging provided by the minds behind Signal. It might just be the largest secure messaging service out there.
