THE PROBLEM
The work is real. Measuring it is the problem.

You can’t read a tape around yourself.
One hand holds the end, the other holds the tape, and the numbers are upside down. Pull a little tighter and you get a different reading.
The scale gives you one number.
Weight is one figure for your whole body. It can’t tell you whether your arms, chest or waist changed.
The notes get lost.
A sticky note here, a phone memo there. A month later there’s nothing to compare, so you stop measuring.
So you train, eat right, and keep guessing.
THE EASY FIX
Loop it. Snug it. Tap it.
The tape closes on itself, a button draws it snug, and the reading goes straight to the free app. No helper, no pen, no guessing.
- 1
Pick a body part
Open the free RENPHO Health app and tap what you’re measuring: waist, chest, left bicep...
2Loop and click
Pull the tape around, then click its end into the slot on the side of the unit.
- 3
Hold to snug
Hold the adjust button: the tape draws in until it sits snug, without pressing into the skin. The number shows on the screen.
4Tap to save
Press the check button: the number lands on that body part in the app. Next part, then Save All.
Two modes, one button
The screen shows the true distance around your body; long-press M for straight lines.
First time? Give it a couple of tries. Waist, hips, arms and thighs are easy on your own; chest, shoulders and neck take a little practice. Tip: close the loop first, then slide it into place. Around the neck, keep it loose and never pull it tight.

Take your own measurements! No waiting for someone to help.
As a single person, I HATE asking friends to help me take measurements, especially measuring certain areas of my body that either require 2 hands or need your body to be in a natural position to measure correctly.
Review on renpho.com
This little buddy solves that problem AND makes measuring quick & easy, too. No need for pen & paper, charts or manual entry. The app is amazing & I LOVE the “trends” feature, which is basically a graph of those measurements. [...] - Sushant D.Apr 17, 2021
Game changer!
If you’ve ever tried to get accurate measurements using a tape measure on your body parts, you know how frustrating it can be. How much tension do you put on? Is it in the right place? What does that number say?? This solves all those problems. It’s an instant digital reading that you can send to an app without messing around. I bought this [...] for tracking muscle growth over time when on a bulk. It does that perfectly. [...]

Worth the money!
If you do your own measurements you should really get this. It makes the process do much easier! I never again have to contort myself, strain my neck or remeasure myself 5 times because the tape slips out of my hands. At first, this product seemed slightly trivial. I mean, why would a tape measure cost so much? Umm, because it’s faster, easier and syncs right to my phone. Well worth it!!!
Review on renpho.com
Good to know before you buy
- The tape is 60 in (150 cm). It can’t wrap anything larger.
- Shoulders, chest and neck take a couple of tries on your own. Close the loop first, then slide into it.
- It measures length and circumference only, not body fat, BMI or body composition.
- Not waterproof. Use it between 32 and 122 °F, away from water.
- Hold it by the sides and don’t press on the screen; pull the tape out smoothly.

Records measurements only: it does not measure body fat. Take care around the neck (keep the loop loose, never tighten hard); children under 10 should use it only with an adult. Don’t fold or twist the tape, and let it retract gently.
FAQ
Questions, answered honestly
Can I really measure myself without help?
Yes for your waist, hips, arms, thighs and calves. The end clicks into the unit to make a loop, a button draws it snug and another one sends the number to the app. Chest, shoulders and neck take a little practice alone; a trick owners use is to close the loop first, then slide it into place (for example up your arm to the bicep).
Which app does it use? Is it free?
The free RENPHO Health app, on the App Store and Google Play. You can sign in with an email or use guest mode. If you already use a RENPHO smart scale, it’s the same app.
How do I connect it? It doesn’t show up in my phone’s Bluetooth list.
That’s normal: it pairs inside the app, not in your phone settings. In RENPHO Health, go to Device, add a device, choose Tape measure (Bluetooth), then switch the tape on. On Android, turn Location on; on iPhone, allow Bluetooth for the app.
What can I measure?
Neck, shoulders, chest, biceps (left and right), waist, abdomen, hips, thighs and calves (left and right), plus custom body parts you add yourself. The app also shows your waist-to-hip ratio from your saved waist and hip.
Why is the number on the screen different from the printed tape?
In circumference mode the unit adds 0.84 in (2.1 cm) for the part of the loop inside the housing, so the screen shows the true distance around. For straight lines, long-press M to switch to length mode. Tip: tap the body part in the app before each measurement so you don’t overwrite the previous one.
How long is the tape? Inches or cm?
60 in (150 cm), enough for most waists, chests and hips, but too short for anything above 60 in. It reads in inches or centimeters: short-press M on the unit, or pick your unit in the app.
What battery does it use?
It runs on one CR2032 coin cell. The cover is held by a small screw (screwdriver not included). The unit switches itself off after 20 seconds without use.
Can more than one person use it?
Yes. Add a profile for each person in the app. If you don’t share a home or a gym bag, the 2- and 3-tape packs give everyone their own tape.
Does it measure body fat?
No. It records body measurements (circumferences). It doesn’t measure body fat.
How often should I measure?
Same spot, same time of day, once a week or every two weeks. Watch the trend line in the app rather than a single reading.
Is it a genuine RENPHO? Who handles my order?
Yes, it’s a genuine RENPHO unit, model RF-BMF01. Lingo is an independent retailer, not affiliated with or endorsed by RENPHO. Lingo handles your order and support: contact us any time. The warranty and return terms RENPHO offers on its own website cover orders placed with RENPHO, not with Lingo.
