With the rise of corporate censorship I don't think its wise to rely on app stores for access to police frequencies. Dedicated radios that monitor police frequencies are widely available and you don't need an amateur license to use one (since you're only listening, not transmitting).

My city is on 700MHz P25 which requires a fairly pricey radio, but its been worth every penny over the past week. After listening in last Saturday we cancelled a trip to visit family after hearing about a riot on the local highway.

Make sure to look up the frequency your town uses first before dropping so much coin on a radio. If your local LE is encrypted, you're out of luck. But many aren't.

Any specific models/manufacturers you can suggest?

You don't have to rely on app stores... Broadcastify is the platform that powers all these apps, and they are online at https://www.broadcastify.com

I have a Uniden BCD396XT, which is a few years old and I'm not sure they make it anymore. However the second-hand market for radios is very strong and if you have an amateur radio store in your area (Ham Radio Outlet, or the like) you can go there and I've found them to be very helpful. They're likely to know the specifics of the LE frequencies in your area.

I've been thinking about upgrading to an ICOM IC-R30, but its expensive and does way more than just police scanning.

Get a Hack RF or other SDR and then just run Unitrunker on a computer.

Police scanning channels are a good way of gaining information about local political activity in your area.

I think at some point you'll feel the pressure to censor those feeds as a way to limit information about demonstrations that aren't approved by the ruling class.

I have a couple of those, but unitrunker only runs in Windows, and I’d hate to run Windows just for that.

Don't you need at least 2 to track trunked systems?

It is helpful, but not necessary. I am listening in on Seattle's trunked radio system with just one, and I get most of the comms.

I documented my setup here: https://dantler.us/seattle-police-scanner/

You need two rtl-sdr, but one hack-rf can grab enough of the spectrum that only one is required. One of the benefits of p25 is that it's very spectrum efficient so I get all 18 channels.

Ah the bandwidth isn't something I'd considered. That's a good point. Unfortunately for me the KCERS Seattle site's total bandwidth is about 6.5 mhz. I have a RTL-SDR and a SDRPlay but it seems like the only thing that can talk to the SDRPlay is their own software.
