About Avalanche Inclinometer

My buddy Mark, who’s annoyingly efficient at everything, told me to ditch the free inclinometer app I was using. He said this one was no-nonsense. I’ve been using it on my Samsung Galaxy A54 for about two weeks now, mostly on weekend tours in the Snoqualmie Pass area. I’m the kind of person who gets irritated if an app makes me tap more than twice to do its one job. My old app felt like a bloated weather widget; this one is a dedicated tool. It doesn’t try to be a GPS or a social platform. It just measures slope angle, and that focus is its biggest strength. For a busy person who hates wasting time, that simplicity is a relief.

Core Features

The main screen is perfect. It’s a giant number showing the angle and a simple dial. That’s it. You open it, and bam, you’re working. I set up angle alerts for 30 and 38 degrees. Now my phone beeps at me, which is a great, immediate heads-up when I’m zoning out on the skin track. It works completely offline, which is non-negotiable. I don’t care about community features or sharing my data; I just want to know if the slope under my feet is in the danger zone. The logging is stupid simple—one tap and it saves the max angle and time. Later, I can see that last Saturday on Commonwealth Basin we hit a 37-degree pitch, which is good info to have.

Real-World Use

This is where it either works or it doesn’t. Last Sunday, around 11 AM, we were looking at a rollover. It looked steep, but was it “turn around” steep? With my old app, I’d be waiting for it to stabilize, fighting with menus. With this, I pulled my phone out of my chest pocket, tapped the icon, laid it on the snow, and had a solid 39-degree reading in under five seconds. That number made the decision for us. We traversed. No debate, no fumbling. The calibration was a one-time thing when I first installed it—just put the phone on my kitchen counter and hit a button. In the field, it’s just immediate. My only real complaint is that in direct, glaring sun, even my max brightness struggles, but I have to squint at my map app too, so that’s a phone problem.

Pricing & Value

It’s four bucks. One time. No subscription, no ads, no begging for a rating. I spend more than that on a terrible gas station coffee. Compared to the thousands I’ve sunk into skis, boots, and avy gear, it’s nothing. For the amount of time it saves me and the clarity it provides in iffy moments, I’d say it paid for itself the first time I used it. It’s a cheap insurance policy that actually delivers useful information right when you need it. I appreciate not being nickel-and-dimed.

Updates & Support

Here’s my big grippe. I had a weird thing happen where the app would occasionally freeze if I opened it while my phone was already in my glove. I emailed support through the app last Tuesday morning explaining the issue on my Galaxy A54. I got an auto-reply instantly, which was fine. Then I heard nothing. I followed up on Thursday. Finally, on Friday afternoon, I got a reply that was basically, “We’ll look into it. Make sure your sensors are clean.” It was vague and felt like a brush-off. For a tool related to safety, even a minor bug report should get a more attentive response. It left a sour taste and makes me wonder about long-term support.

Data & Privacy

I checked the privacy details before buying. The listing says it doesn’t collect any data. It doesn’t ask for any permissions, which I like. My slope readings and logs stay on my phone. I don’t want some company having a log of where I’ve been and what slopes I’m measuring. It feels clean and self-contained, which is exactly how a tool like this should be. There’s no account to create, no cloud sync begging to be turned on. It’s just an app on my phone doing its job.

Frequently asked questions
What are the core features of Avalanche Inclinometer?

The app displays a large, easy-to-read slope angle number and a simple dial on its main screen. It also allows you to set customizable angle alerts (like 30 and 38 degrees) and log the max angle with one tap, all while working completely offline.

How does the angle alert system work?

You can set alerts for specific slope angles, such as 30 and 38 degrees, directly in the app. When you're on the skin track and your phone detects that angle, it beeps to give you an immediate heads-up without needing to check the screen.

What should I do if the app isn't giving accurate readings?

First, make sure you've completed the one-time calibration by placing your phone on a flat surface like a kitchen counter and tapping the calibration button. If readings still seem off, check that your phone's sensors aren't obstructed by a thick case or magnetic object.

Why does the app sometimes take a long time to show a stable reading?

This can happen if the phone is moving or if the snow surface is uneven. To get a quick, stable reading, lay the phone flat on the snow and hold it still for a couple of seconds—the app typically stabilizes in under five seconds when used this way.

How does Avalanche Inclinometer compare to free inclinometer apps?

Unlike many free apps that feel bloated with weather widgets, GPS features, or social platforms, this one is a dedicated, no-nonsense tool. It focuses solely on measuring slope angle, so you can get a reading in seconds without fighting menus or waiting for the app to stabilize.
