AppLock
AppLock is a free Android app that comes with a lot of options. You can
pay for it, get premium features, and no advertising. Or you can view
advertising, get the premium features, and not pay anything. Finally,
you can use it ad-free, but without premium features. The choice is
yours. The app itself is a simple, but powerful app that allows you to
lock your apps up tight with passwords so that snooping eyes can’t see
them. This is great if you have nosy roommates, kids, or if you just
want some piece of mind. You can use the app for free with or without
ads (your choice). The ad-free version has a few features missing, but
the ads will unlock those features as though you paid for it.
Credit Karma
Credit Karma is a fun little financial app. What it does is let you
check your credit score once per year for free. On top of that, the app
will notify you when there are major changes to your credit score. The
app offers some other things too, such as potential credit cards that
you may qualify for based on your credit score. You don't have to accept
those if you don't want to. It's a simple, easy way to check out your
credit and start fixing things if needed. It's one of the more
underrated free Android apps.
Google Drive Suite
The Google Drive suite are a group of applications that are all directly
integrated into Google Drive. The apps include Google Docs, Google
Slides, Google Sheets, Google Photos, and Google Keep along with the
actual Google Drive app itself. These apps focus primarily on office use
for documents, spreadsheets, and slideshows but also work for note
taking, backing up your photos, and storing whatever file you can think
of. The best part is that they’re all free unless you need more than
15GB of storage on Google Drive. Most people don’t. These are all great
free Android apps.
Groupon
Groupon is one of the best and most popular coupon apps available on
Android. Using this application is very simple. You browse it for
coupons for goods or services you want and then you take those coupons
shopping with you in order to get discounts. It doesn’t have coupons for
every little thing but any penny saved is a penny earned. You can track
which coupons you’ve used, take advantage of deals instantly, and a lot
more. The design isn’t half bad either. It's one of those free Android
apps that are worth a shot.
Maps and Waze
Google Maps and Waze are two navigation apps. Google Maps will give you
turn-by-turn directions, let you view businesses (and their reviews),
and all kinds of other stuff. Waze is another navigation app. It lets
you check out the traffic along your route. Google Maps is definitely
the more powerful of the two. However, Wave is less bloated. That makes
it a good option if you're looking for something simple. You can't go
wrong either way.
