Not sure if this is what you are looking for but...
Firstly you need to decide if you are aiming for accuracy or matching.
Most phone screens are set to a more vivid/saturated colour profile to make things pop rather than aiming for accuracy so check if your phone supports an accurate colour profile if you want it to look closer to the monitor. Most people leave there devices on the default colour profile though so it's best to leave it so you can view your work as it would appear to most people even if it is not an exact match for your monitor.
For accuracy any of the external devices will help get you consistency accross your screens but some are better than others for various reasons which include:
- Speed - the more expensive models tend to get you a result faster
(not usually an issue unless you are working on many displays on a
regular basis)
- Better accuracy - improved colour accuracy through
better lenses etc
- Additional features - some provide ambient light
monitoring that adjust the screen colours relative to the light in
your room (I actually don't like this feature)
- Ease of use - some of the cheaper models are a bit more fiddley to setup or have more chance of a bad result as they were not in the perfect position etc.
- Supported monitors - some do not support super bright, HDR, or wide colour gamut screens and so you'd need to get one that meets the capability of your monitor.
Each manufacturer will tell you why one model is better than the other within their range claiming their newest/more expensive model improves on the previous/cheaper one but to be honest for most people the entry level models are ok.
