At this price, the scale competes with models that lack some of what matters, such as body composition estimates, automatic app syncing, and multi-user support that’s friendly to households.
Why this deal matters for budget-friendly smart scales
Smart scales from reputable brands usually fall between $25 and $60, while high-end options can surpass that range for features such as Wi‑Fi or color displays. A $19.99 price point for a well-liked model comes out to about $15 in savings and amounts to an easy decision if you’re looking to upgrade from a basic “weight-only” scale.
Renpho is a hit among Amazon shoppers who are interested in monitoring their weight, as it offers wide app compatibility and a simple setup. It hits the value sweet spot for a lot of buyers — no subscription fee, useful trend charts, and just enough metrics to inform a training plan without overwhelming your day.
What this Renpho smart scale measures and estimates
Four high-sensitivity electrodes use bioelectrical impedance analysis (BIA) to estimate 13 body composition measurements, including:
- Weight
- BMI
- Body fat %
- Muscle mass
- Bone mass
- Body water %
- BMR (kcal)
- Protein
- Visceral fat
BIA is not a medical device, but it’s useful in following directional change over weeks and months.
A BIA refresher: a harmless electrical signal travels through the body, and the scale estimates composition through resistance. Hydration status, what you’ve most recently eaten, or if you’ve worked out can skew the readings, which is why everything should be measured under consistent conditions. Sports science literature suggests, for reference, that consumer BIA is within about 3–5% of DEXA for body fat, but there is, obviously, always variation.

App and ecosystem compatibility and privacy options
Data syncs to the Renpho Health app and can be sucked into Apple Health, Fitbit, and Samsung Health for a glance at how your weight is trending along workouts, steps, and sleep. The app is free, with basic features available, and offers multiple user profiles, as well as baby and pet modes for lightweight readings.
For privacy-savvy people, it’s worth reviewing permissions for apps and toggling off third-party sharing if you don’t want the data going out of your phone. You can still see long-term trends and export summaries if you wish to share your progress with a coach or clinician.
How to make your smart scale readings most accurate
For accuracy’s sake, weigh yourself at the same time each day (preferably in the morning before food or exercise). Stand with feet bare and dry; place the scale on a hard, flat surface — no carpet. Since hydration meaningfully impacts BIA, compare like with like — don’t weigh a post-workout reading against a well-rested morning one.
Consider the numbers as trend lines, not absolute truths. If a little muscle mass here and there is heading in the right direction, or body fat is generally trending where you want it to go over a period of several weeks, you’re on course — even if day-to-day hiccups are all over the place.
Who will benefit most from this Renpho smart scale
Novices mapping a wellness plan, strength trainees tracking lean mass, and families that want to share a single scale for multiple profiles all find good value here. Features like the baby and pet modes offer versatility, and the scale is often FSA- or HSA-reimbursable, which can help make those health dollars go a little further.
Important: users with implanted medical devices, including pacemakers, should not use BIA scales and should consult a healthcare professional. Pregnant women should adhere to manufacturer guidelines for body composition estimations.
Bottom line: is the Renpho Smart Scale worth $19.99?
For the price of $19.99, you cannot beat the Renpho Smart Scale — a solid blend of cost, metrics, and app integration. If you’re looking to refocus away from a single number on the scale and get a richer snapshot of body composition along with trends, then this deal makes an argument that upgrading while it’s at its lowest price ever is a hard one to ignore.
