Halide does focus peaking, albeit only in manual-focus mode.

In general, though, you're right - I wouldn't want to try for the same kinds of shots with a phone that I get with a DSLR. My macro rig weighs about five pounds, which sounds like a lot and is in comparison with a phone, but between the damping effect of all that mass and the ability to get a good grip with both hands, it makes for a much more stable platform overall.
