FreeSpace displays the true free space in your drives as a menubar app. It shows the true free space in the drive with regard to the presence of the hidden local Time Machine snapshots in your drive. See Apple's own knowledge base:
Recent releases of macOS on AFPS have local Time Machine snapshots enabled by Apple. That means some space would have been taken and hidden as local backup. This backup space is called purgeable space. It will automatically be reclaimed by macOS when the drive is running low on space. FreeSpace displays the true unused space with regard to the presence of the snapshots. But Finder does not. The two different interpretations of free space can also be seen in Disk Utility. Generally the difference can be safety ignored.

"FreeSpace’s systemwide menu shows all mounted volumes along with the available free space on each; if you want to monitor a particular volume, you can choose to have that volume’s free space displayed right in the menu bar."
"FreeSpace is one of the best free space monitors available out there. It's fast, reliable, low on resource consumption (during the testing process it constantly occupied 10 MB of RAM) and stable (it never crashed)."
"FreeSpace is a tiny menubar utility that can show you how much space is available on all local, connected, and network drives with a single click."
"I do recommend it. This is a cool little app that is very useful, easy to use"
"A very useful and simple application that once you start to use, you can never do without."

Handy, but a few bugs
This is a great app! It has proven to be very handy for ejecting drives/memory cards, etc. I am a photographer and am always hunting around trying to see what is mounted (and what isn't) by opening new folders, or searching around the desktop. This app has made seeing what is mounted, how much room it has, and easly ejecting devices much, much easier. It never has the correct amount of free space for the internal ssd on my MBP, however. It is always wrong and is frequently wrong on external devices, too. Wish that bug could be squished.

Thanks for your concern. Your Mac and external drives are probably in APFS, which always hides away hidden local snapshots. FreeSpace takes the backup into consideration.
Two great features
The notifications when a disk/thumbstick is mounted or unmounted are great. MacOS can have a notable lag between when you physically initiate an action (plug something in, or press "eject") and when the device becomes available (to work with, or to physically remove); this app's notifications tells you when something has actually happened so that you can actually proceed. Extremely useful.
On my space-starved laptop, it's very useful to always see the amount of fee disk presented in the menubar.
5 stars for usefulness.

Thanks for writing for FreeSpace. It is an indispensable app written for myself and I use it everyday in every of my Mac. I am so happy that many users like it as much as I do!
Speedy access to open eject drives. HIghly recommended!
Indispensable. Lists all drives, DMGs or external; eject individual drives with a single click each or all drives with one click. Or, you can easily open the drive from the Freespace list. Gone are the days I needed to move app windows to find a drive on the desktop or to open a folder window to get to the drive list on the sidebar. You can set up Notifications to show each ejection.

FreeSpace comes in handy when you have a list of drives. They are all click-away under your menubar!
