Yes, it's a wide angle lens with the following very nice properties:
16mm-50mm equivalent focal length (to 35mm full frame) due to m4/3 2x
Constant f/4 throughout the entire focal range

It's kind of weird that you are hiding half the fact. It does equivalent to 16 mm to 50 mm ff focal length, at the same time, about f/8 aperture to a full frame.
is the same reason why you don't think your phone's F/1.6 aperture is that impressive.
Full frame and micro 4/3rds have different aspect ratios. In fact, we should thank them for providing this as supplementary information to make an educated purchase.
No time machine obviously, but a price point for comparison. I bought the 40-150mm reconditioned from Olympus direct for $500 in January. Other than the box that said "reconditioned", you would never know it wasn't new. Might be worth a search if that size interests you.

Not looking for either of these right now, although I think the 40-150 could be an interesting choice for ski photography. Plenty of light for f4 and you can take wider shots on your iPhone…but the iPhone can't deliver anywhere near as good zoomed in action shots.

Only the background blur is to be equivalent to F/8 for fall frame , but the low light performance is still at F/4 level. If you want F/4 for faster shutter speed or lower ISO under low light, this lense still delivers it.

if you are sold on that concept, then you should have no issues loving your phone's F1.6 lens for low light, actually why even bother with this lens or any MFT/APSC/FF/MF/LF camera at all, since cellphone lens are typically no smaller than F2.2, most are at F 1.6 or larger. don't bother with the computational image either since the F number is so large. certainly beats the heck out of F4 on the paper.
the fact that is that the the total light input matters, not just on the square inch level. while the F number meant something back in the film days as the chemistry mixture of the film determines the ISO, today's digital camera are largely single native ISO, maybe dual ISO. everything you see is a multiplication and amplification to the native signal. any other ISO is it is just a number multiplier to that signal to boost luminance. your noise level, on the other hand, depends on the total light input. within the same generation of technology, larger sensor that gathers more light with the same aperture lens will allow more light and lower the noise level.
in short, the equivalence is not just for bokeh, it is for imagine quality as well. so if you want to talk about equivalence on the focal length, you better also talk about equivalent aperture. because a F4 lens will always be bigger than a F8 lens of the same focal length. when you factor everything in, you will find out you don't actually save that much in weight or the size. e.g. a 50 mm F2.8 for MFT isn't much smaller than a 100 mm F5.6 FF, and lo and behold.. they produce pretty much the same image.
F4 on M43 and FF will both have the same Exposure, not image quality. When curmathew stated the below statement, he was obviously referring to the exposure since if the F4 was not the same, you would need to either lower your shutter speed or increase ISO to compensate.

A 25mm F1.8 on a OMD Em-10 and a 50mm F1.8 on a A7IV are different in size and weight when you go out shooting for a day, need to throw it into your bag while traveling light, etc. While there are exceptions, most lenses and bodies are smaller on m43 than FF.

Too bad it doesn't have sync IS though.
