PeakFinder

Review by eFreeware

Most apps that identify a landscape need a signal. PeakFinder is built the other way around: it draws a labeled 360-degree panorama of the peaks around you and does it offline, anywhere in the world. Over a million summits are in its directory, from the biggest names down to the hill at the edge of town.

That combination is what makes it interesting. You point the phone at a ridge and the app shows which summits you are seeing, without a network connection and without a monthly bill. I'd expect it to appeal to hikers, climbers, ski tourers and anyone who travels through mountain country and wants to know what is on the skyline.

It is a paid app, $5.99 once, with no ads and no in-app purchases, and it has been on Google Play since March 2011. More than 500,000 installs and a 4.2 average from over 14,000 ratings suggest a settled, well-used tool rather than a novelty.

What the panorama actually shows

The core of the app is a panorama drawing of the surrounding landscape, rendered in real time out to roughly 300 kilometers, or 200 miles. Every peak in that view can carry a name, which is the whole point: the drawing is not scenery, it is a labeled map wrapped around you.

The app can also overlay that drawing on the camera image, so the names sit on top of the real ridge line in front of you. That is the feature most people will reach for first, and it is the one with a catch. On a phone without a gyroscope and a compass sensor, camera mode is not supported, so the panorama stays a drawing rather than a live overlay. If you are buying specifically for the camera view, it is worth checking your device's sensor list before paying.

A digital telescope helps with the peaks that are not obvious, letting you pick out summits that would otherwise go unnamed in a crowded skyline. There is also a show-me function that points you toward visible peaks, which sounds like the quickest way to settle an argument about which mountain is which.

The features around the main view

Where you stand matters, and the app gives you three ways to set it. GPS puts you where you are, the peak directory lets you pick a named summit as your viewpoint, and an online map offers a third route. The map option is the one that needs a connection; the rest of the app is built to work without one.

You can mark mountains and places you like, which turns the app into a record of trips rather than just a viewer. There is also a bird's-eye mode that flies you from peak to peak and straight upward, a way to survey a range without moving your feet.

Sky information is included too: the app shows the path of the sun and the moon along with their rise and set times. For anyone planning a hike around daylight, or timing a shot of a summit at golden hour, that is a useful layer on top of the terrain view. Compass and motion sensors feed the display, which is why the hardware matters here.

What it asks of you

The cost is straightforward. PeakFinder is $5.99, paid once, with no recurring charges, no advertising and no in-app purchases. The developer is explicit that you pay a single time, which is unusual enough among travel apps to be worth stating plainly.

The other requirement is hardware. Camera overlay depends on a gyroscope and a compass sensor, and phones without them lose that mode entirely. Everything else, including the panorama drawing itself, is presented as working offline and worldwide, so a trip abroad does not depend on roaming data or a local SIM.

The peak directory updates daily, which matters for an app whose value rests on its names being right. The most recent update brought a new elevation model with more terrain detail at the same data size, so the shapes in the panorama should be drawn more precisely than before.

Getting the most from it on a trip

The sensible approach is to set your viewpoint before you lose signal. Choose your position by GPS while you still have one, or pick the summit you are heading for from the directory, and the panorama is ready when you reach the ridge. The online map option is best treated as something to use at home while planning rather than on the trail.

Once you are out there, the digital telescope and the show-me function do the heavy lifting on a busy skyline. Marking the peaks that matter to you as you go builds a personal list, and the bird's-eye flight is a good way to get oriented in an unfamiliar range before you commit to a route.

The sun and moon times are worth checking the night before rather than on the morning of a hike, since they shape when you want to be on a summit. If you are traveling through several ranges in one trip, the offline worldwide coverage means the same app works in each of them without any setup in between.

A one-time purchase for mountain country

PeakFinder does one job and does it without asking for a subscription: it tells you what the mountains around you are called, from a directory of more than a million peaks, with a labeled panorama that works offline and worldwide. The camera overlay, the telescope, the show-me function and the sun and moon times all support that single purpose.

It suits hikers, climbers, tourers and travelers who spend time in mountain country and want a reference that keeps working when the signal drops.

The one thing to confirm first is your hardware. Without both a compass and a gyroscope in the phone, the camera view cannot work, so the app turns into a drawn panorama instead of a live overlay. For anyone with a modern handset who wants to put names to a skyline, this is an easy recommendation.

What's new in version 4.9.2

PeakFinder uses a new elevation model. It contains more terrain details while the data size stays the same, so the mountains are displayed even more precisely.
