As already said, NONE of the bathroom scales or BIA scales or handheld devices will be anywhere near even relative accuracy. This has been answered in other threads.
BIA scales, handheld monitors, or anything that uses an electrical current to measure body composition are the most INaccurate ways to measure body composition. For a start, they are dependent upon how hydrated you are and a variety of other factors, including temperature, time of day, whether you have trained or eaten prior and how long ago that was, etc; and, unless your bodyfat is distributed evenly over your body (which for most people, it is NOT) then the reading is going to be far from accurate (i.e. scales only measure the body composition of your LOWER body; handheld devices measure your UPPER body or ONE SIDE of your body, etc. The reading you get is usually out by up to 10% bodyfat, and usually gives a higher reading. At best, if all factors are controlled, then it can provide a ballpark figure, or something that you can compare reading against reading to, but not to be taken as serious.
The 'gold standard' of BF% calculations is done by underwater weighing. But this can be very expensive and impractical.
The next best thing is to get either 6 or 8 skinfolds done by someone who KNOWS what they are doing (i.e. ISAK certified), and calculate it from there. Factors still need to be taken into account, but if your anthropometrist knows their stuff, then skinfolds can be accurate within a 3% margin.
As mentioned by wearedbleedblue, you don't need to check daily. Weekly or even monthly is fine enough. You should be able to tell by the fit of your clothes and what you see in the mirror, if you are losing bodyfat or not. And if you know your body well enough, and what you look like at different body compositions, you will be able to know what you are about, just from looking in the mirror.
