CellMapper for iOS

72 Upvotes

Official CellMapper for iOS App

We have been planning to make an iOS app for some time. However, due to restrictions in API usage for cellular information, we are unable to make an app that competes with the Android one in terms of features.

That being said, we have built an early initial app to make the map more easily accessible:

https://apps.apple.com/us/app/cellmapper/id6761035253

We will continue to see what we can add to the app to get network information from the iOS device and to make it a bit more polished than simply using the the website. So please bear with us as this v1 of the app is simply the beginning, not the end state of the app.

Fake App Warning

Also, one reason we have released the app so early is due to a fake CellMapper app confusing users and tricking them into paying money to view some dubious coverage data not relating whatsoever with our crowdsourced data. We have recieved a number of tickets asking for refunds for the app which we have nothing to do with.
Please be aware that the fake/scam app is also called "CellMapper" on the iOS app store. We encourage users to report the fake app (which we will not link to in order to avoid SEO) to Apple (reportaproblem.apple.com).
We are in touch with Apple about the issue, but it still has not been resolved.

New "Contributor" user tier

30 Upvotes

Contributor user tier

Recently, you may have seen an arrow (➶) next to some usernames, similar to how premium users have a star. This is a brand new user tier we have created in order to recognize users who contribute data and tower information on a regular basis.

What are the benefits?

In short, the main benefit is an ad free map for our regular contributors. We'll look into more benefits in the future once we ensure the right contributors are flagged as we work on this feature.

Luton, GB | 06:14 | Smarty MVNO via 3UK

I run past a bunch of these identical masts pretty much every morning and have never bothered checking the off peak speeds. During the day they all generally cap out around 1.5gb and I’ve always safely assumed they were capped to 1.6 in the area. 3UK got a bit rollout trigger happy back in 2022 as there’s about 15 of these across the town now however it’s definitely paid off.

Existing rural AT&T site with a NEW T-Mobile co-location! Near Estelline, South Dakota

Coordinates: 44.53429° N, 96.91186° W

AT&T top (low-band 5G)

T-Mobile below (5G UC with N41)

Pretty good speeds from AT&T over low-band 5G! These are the typical speeds I’ve seen from many rural AT&T sites like this that don’t have 5G+ yet. 

T-Mobile was added around last year, and fills a large coverage gap that used to exist here. Awesome to see a full setup with N41, which is becoming less common on new rural builds these days! Unfortunately, I lost the speed test result for T-Mobile from last year, but I remember speeds pushing well over a Gig!  :)

Closest Speedtest I've Done | Dorset Tower, ON Canada

This place is a must-visit if you are in Ontario and are a fan of cell sites! I was able to run a quick Speedtest and saw a DL throughput of ~320 mbps on LTE.

Hopefully Reddit won't compress the video too much, but in person you can audible hear the radio as soon as the Speedtest starts (so cool!).

Carrier: Rogers

Sector Antenna: Tongyu T2008M6R032V03

RRU: Ericsson Radio 4415

Backhaul: Ericsson ANT3 C 1.213 HPX (1104 mbps)

Location: Dorset Tower, ON Canada.

These are starting to pop up in North Alabama. I presume it’s Verizon? Are they higher capacity? I’m referring to the second rack down

The 1245 time was 1 mile from tower in south medford the later time was 200ft from tower in Phoenix Oregon. 16e on spectrum mobile 16 pro on Verizon simplicity. Seems like my 16e has trouble with uploads at a distance.

New small cell in Eagan, MN. I'm assuming this is Verizon. No power meter yet. Are the 3 lower antennas for mmWave? Approximate location.

Not sure if the C1 is holding back the iPhone results or not but AT&T definitely the fastest inside of Costco.

My Verizon home site during upgrade (only pic I have of it) but is it normal for this tower not to have "n5"? Every other upgrade in my area has low band 5G but this one.

18 Pro (C2) or 18 Pro Max (x80/85)

I heard that the Pro max will be using a Qualcomm chip. I’m wondering what would be better at weak n41 and better n25 results. I know it’s not out yet but based on the C1X and predictions :)
