In the app description, Last App Description equates itself to the “last channel” button on your TV remote and we think that description is apt. What this app does is keep a floating notification open and when you click on it, it will take you back to the last app you had open.
This is really handy if you’re doing something, need to take care of a notification, email, or message and then get back to what you were doing quickly. Yes, it’s just as easy to hit your recent apps button but this actually takes a step out of that process for those who want it to go just a little bit more quickly.
Aside from its main function, the developers have also added alternate methods to use this app in case you’re not a fan of the floating button. Aside from that, Last App Switcher does what it says it does and gauging from the user reviews, it does it fairly well.
A little time saved now is a lot of time saved later.
It seems like it only saves a little time but over time it'll add up.
Free to use with no in app purchases.
Alternate setups available if you don't like the floating notification.
Very easy to set up and use.
Very responsive developers
Doesn't work on some custom ROMs,
While it is insanely useful, there will be those who find the recent apps button more useful or just as useful.
Overall, it’s a free app that can save you a little bit of time and most users were impressed with how often they actually used it. It’s free with no in app purchases so why not?
