What is Reddit's opinion of TowerLocator Canada?

From 3.5 billion Reddit comments

I've only backpacked through Killarney, but service in the backcountry parking lot (which is in the middle of the George Lk Campground) is ok-ish - on a couple of different occasions, I've been able to upload (Bell) trip photos and videos from my truck after a trip.

But... I suspect service will depend on where you are in the campground. That parking lot is at the top of the hill whereas most campsites are on the hillside toward the lake. Looking at the Tower Locator app, the closest towers are just outside the town of Killarney. Looking at the Coverage? app, which has the latest carrier maps, the George Lk campground is on the edge of Bell and Rogers coverage. But, worst of all, OpenSignal has *no* reports good-or-bad from George Lk.

The exact same app can be found on the Play store: https://play.google.com/store/apps/details?id=org.ertyu.towerlocator

It says they have an Android app right at the bottom of the page.
