The new Bosch GLM 100 C laser distance measuring tool is not the first laser measuring tool I have had the pleasure of using or testing, but it is the first that features Bluetooth connectivity. As such, there was a little bit of a learning curve, but it wasn’t long until I figured out all the ins and outs of using the tool alongside Bosch’s software app.

Bosch Laser Measuring Tool
The GLM 100 C laser measuring tool can be used to make many different types of measurements: length, area, volume, angle, min/max, continuous, single indirect height, single indirect length, combined indirect length, and multi-surface area.
What I Liked:
- Small pocketable size (4-3/8″ length)
- Built-in angle/tilt measurements
- Easy to figure out and use (in case you lose the manual)
- USB charging
- Easy connectivity to smartphones
- 1/4″ tripod mount
- Backlit LCD screen with wide viewing angles
- 50-measurement memory
- Customizable imperial and metric units
- Units can be represented in decimal format (eg. 1.542 feet), or fractional units (1′ 6″ 1/2″ )
What I Didn’t Like:
- USB charging port cover flaps open and closed at its whim
- Tripod mount has plastic and not metal threads (but to be fair, the threads are deep and well formed)
Bosch Laser Measuring App
The app is actually a LOT easier to use than I had anticipated. I did get stuck one or two times, but the help menu sorted things out.
With the app, you can log measurements (automatically as well as manually), transfer measurements to photographs (sketches), save or share annotated and overlayed images, and maintain separate projects. You can even remotely control the laser measuring tool.
I spent quite a bit of time with the app, and thus far I only found one bug. When entering in manual measurements, there is no option for selecting units. I set measurements to be displayed in imperial units (feet) instead of metric. When typing in a manual measurement, it asks for a unitless number but ignores my user preferences. If I enter in “1,” the measurement is logged as “3.28 ft”.
I didn’t expect the app to be perfect, but it is actually very intuitive to use. You can swipe one measurement onto another and then add, subtract, multiply, or divide one from the other. You can also do compound measurements, and the app is smart enough to only allow certain operations. For instance, it didn’t let me multiple two area calculations with each other, but it does allow an area measurement or calculation to be multiplied against a linear measurement to calculate volume.
Bosch’s GLM 100 C laser measuring tool is a solid tool by itself. Its measurements are spot-on, its controls are easy to use, and every aspect seems well thought out. And when the measuring tool is used together with the free app, the result is a very streamlined user experience.
Bosch did a great job in designing the GLM 100 C, and it is obvious they worked at great lengths to perfect the app.
If you’re not interested in wireless Bluetooth connectivity, Bosch’s GLM 80 laser measuring tool offers similar functionality at a much lower price ($170-200 via Amazon).
If you’re on the fence between models, you could (and should) download the free app in advance to see how well you like it. While you won’t be able to test out the remote control or automatic measurement logging or download features, you will be able to test the app’s image overlay and export functionality.
If you are looking for a Bluetooth-equipped laser measuring tool with greater range, the Leica Distro e7500i can be used at a range of up to 650 feet.
As always, let me know if there are any questions. For the time being the GLM100C is staying in my layout and measuring tool bag, and the app is still on my phone.
Thank you to Bosch for providing the review sample unconditionally. Review samples are typically given away, donated, or retained for benchmark and comparison purposes.
