Bagel: The World’s Smartest Tape Measure


Bagel is the only tape measure you will ever need. With three different measuring modes, Bagel lets you measure just about anything.

It can also save measurements, record voice memos, and send data to its mobile app, where you can easily organize and analyze your measurements. That’s why we call Bagel a smart tape measure.

We all measure size in our daily lives. Whether it’s for a DIY home improvement project or for measuring body size, everyone uses a tape measure.

Despite the various uses for a tape measure, the way we measure size has remained the same for more than a century. It’s about time that we stop trying so hard to read tiny numbers and markings on tape measures.

Bagel is easy to use. Select one mode from three different measuring modes, take a measurement, then click the save button to save your data.

You can also choose to add a voice memo that describes what you measured. As soon as you connect Bagel to its mobile app, this voice recording will be automatically converted into text and tagged to your measurement.

Three Measurement Modes

String Mode

You can use Bagel’s string mode to measure length like you would with a traditional tape measure. Its flexible yet strong string allows you to easily measure curved objects and surfaces, various body types, and- needless to say- flat surfaces. Bagel’s string mode can measure up to about 10 feet (3 meters).

Wheel Mode

Wheel mode is great when you don’t have both hands available to measure length or distance. Just switch to Bagel’s wheel mode and roll its wheel. Wheel mode is perfect for measuring distance on curved surfaces and can measure up to about 33 feet (10 meters).

Remote Mode

When you want to measure the distance to areas that are far away or hard to reach, use Bagel’s remote mode. Simply point the ultrasonic sensor at objects, walls, or ceilings and Bagel will tell you how far away they are. The remote mode automatically activates a laser that points at your target spot to indicate where you are measuring. You can measure up to 16 feet 4 inches (5 meters) in remote mode.

Additional Features

Saving Data & Voice Memos

After taking your measurement, save the data with just a click of a button. You can also choose to record a voice memo that describes what you just measured. Never experience the hassle of going back and forth between your notepad and tape measure!

Bluetooth Connectivity

We wouldn’t call Bagel smart if that was all. You can connect Bagel to your smartphone via Bluetooth and transfer all of your measurements to Bagel’s mobile app.

Mobile App

Use Bagel’s app and never lose measurements again. You can browse through your measurements, all of which are tagged with a voice memo. Additionally, take advantage of the app’s ability to export your data as CSV to use on your computer.

If you want to track your body size, simply open up a graph that will display how your measurements have changed over time.

Both iOS and Android versions of the mobile app will be available for free.

Internal Memory

You don’t have to connect Bagel to your smartphone every time you want to take a look at past measurements. Bagel has internal memory that can save up to 100 measurements and voice memos. You can easily bring up all of your logs on its digital display.


There’s no need to worry about replacing the batteries. Bagel is built with a lithium polymer battery that lasts up to 24 hours and averages 8 hours with constant use. Any micro USB cable lying around the house is fit to charge Bagel.

Selectable Units

Bagel is for everyone. Whether you use inches, centimeters, or millimeters to measure size, Bagel will adapt to meet your needs. On Bagel’s mobile app, you can even choose to display your measurements in feet or meters.


Bagel’s sensor is backed by six patents that make it accurate. The error for all three modes should be within 0.5% under room temperature conditions. The engineers of Bagel are working hard on its firmware to lower the error margin and will provide all updates on any accuracy improvements.


Bagel’s casing is made of polycarbonate, which is known to have very high impact resistance. Bagel can withstand being run over by a car and a drop from 12ft (3.7m).
