Compass

Review by eFreeware

The most distinctive thing about Compass is how little it tries to do beyond being a compass. Fatih Balsoy has built a $0.99 tool that pairs a dark, minimal interface with the practical extras you would want in the field, and it runs on Android phones and select Wear OS smartwatches. That combination of a narrow focus and a small one-time price is unusual.

It suits people who need a reliable heading and a clear readout rather than a full navigation suite. Hikers, travelers, carpenters and DIY enthusiasts are the intended audience, and the app covers coordinates, saved places, a bubble level and a calibration guide. If your phone is already your main navigation device, this is the sort of utility that sits alongside a maps app rather than replacing it.

Coordinates and saved places in the field

The coordinate readout is the part I would use most. Compass shows your location's coordinates along with altitude, and it supports DMS, DDM, DD, UTM, MGRS and OLC (Plus Codes). That range matters because different activities expect different formats: a hiker following a paper map may want UTM or MGRS, while someone sharing a location with a friend may prefer decimal degrees or a Plus Code. A recent update added a dedicated page for your current location or your saved places' coordinates, where you can copy them in any of those formats.

Saving places turns the compass into something more useful than a single heading. You can store a location and then see its direction and distance from wherever you are, which is the kind of thing that helps when you are returning to a trailhead, a parked car or a campsite. Because the app works without an internet connection, those saved places remain usable in areas with no signal, which is often exactly where a compass matters most.

Altitude gets its own set of choices. Mean Sea Level is the default reference now, and the Units & Formats page lets you change it to WGS84 if your other tools rely on that standard. For angles you can pick Azimuth or Quadrant Bearing, and distances and altitude can be shown in metric, imperial or nautical miles. None of this is glamorous, but it is the difference between a readout you can act on and one you have to convert in your head.

A level, an angle gauge and a magnetic field readout

The integrated bubble level is the feature that broadens the audience beyond walkers. It lets you check how level a surface is, and a recent update added the ability to take measurements with it as well. For carpentry, hanging shelves or setting up a tripod, that is a genuinely separate job from finding north, and having it in the same app saves reaching for a second tool.

It can also show the angle between two orientations. That is a niche capability, but a useful one when you need to work out how far apart two bearings are rather than just read a single heading. It is the sort of thing that rewards a little thought about what you are measuring, and it fits the app's overall character: a small set of tools that each do one job cleanly.

Sensor health is handled more openly than I expected. The app shows the current magnetic field strength around the device in micro-Tesla, and an anomaly detector warns you when something nearby disturbs the sensor. Anyone who has watched a phone compass drift near a magnet or a metal desk knows how frustrating that can be, so having the app tell you something is wrong is more helpful than silently showing a bad heading.

Reading it at night, in the sun and on a watch

The display options are clearly aimed at real conditions rather than screenshots. You can switch between dark and light themes, use Android 12's dynamic colors to match the app to your wallpaper, or turn on a high contrast mode for better visibility. The red screen filter is the one I would single out for night use, since it reduces the light the screen throws off; it requires Android 10 or later.

Haptic feedback is part of the experience too, giving a tactile response as you navigate. On a phone that is a small touch, but on a Wear OS watch it is more significant, since you may be reading the compass at a glance with a hand already occupied. The app is available on select Wear OS smartwatches, so the watch version is worth checking against your own model before you buy.

Keeping the compass docked at the screen edge while you work in other apps is the feature I find most practical on a phone. It means the heading can stay visible over whatever else you are doing, which is useful when you are cross-referencing a map, a note or a message. It turns the compass from an app you open into an overlay you keep.

What you need before the first reading

Setup is deliberately light. A simple calibration guide walks you through getting accurate readings, and calibration is the one step that matters for any phone compass: the sensor needs to know its environment before the heading can be trusted. The guide is there to make that straightforward rather than leaving you to guess.

The red screen filter needs Android 10 or higher, and dynamic colors need Android 12. There is no internet connection required at any point.

The privacy position is unusually clear. The developer says the app contains no trackers or analytics, and there are no ads. Since it works offline, there is no obvious reason for it to phone home. That combination is the main reason I would consider paying for a compass when free options exist.

Who gets the most from a paid compass

This is a tool for people who already know they need a compass and want one that stays out of the way. Hikers and travelers will get the most from the coordinate formats and saved places. Carpenters and DIY enthusiasts will get more from the bubble level and the angle measurement. Anyone who works outdoors at night will appreciate the red filter, and watch owners get a version they can read without pulling out a phone.

The narrowness is the point. Compass does not try to be a map, a route planner or a fitness tracker; it gives you a heading, coordinates, a level and a few related measurements, and it does so without advertising. If you want a single-purpose instrument that behaves the same way whether or not you have signal, that is exactly what this is.

The $0.99 price is a one-time cost, and there are no in-app purchases. With more than 10,000 installs and a 4.9 average from 241 ratings, it has found a small but evidently satisfied audience. I would treat those numbers as a sign that the app does what it claims rather than as proof it will suit you, but they are encouraging for a paid utility.

A focused instrument worth the small price

The coordinate format support covers several formats, the unit choices cover metric, imperial and nautical preferences, and the magnetic field readout with its anomaly detector is a thoughtful addition. The $0.99 price is easy to justify for something you may rely on when signal is gone.

The trade-offs are mostly about scope and requirements. It is a compass and level rather than a navigation system, watch support covers select Wear OS models, and the red filter needs Android 10 or later with dynamic colors needing Android 12. If those fit your device and your needs, there is little here to argue with.

I would recommend it to hikers, travelers, carpenters and DIY users who value a simple interface and a private, ad-free tool. It was released on July 3, 2024, and last updated on September 4, 2026, with the recent changes adding a coordinate copy page, bubble level measurements and more than 160 waypoint icons. For a small one-time purchase, that is a well-defined and well-maintained instrument.

What's new

- Mean Sea Level is now the default altitude reference. You can always switch back to WGS84 in the 'Units & Formats' page. - A new page dedicated to your current location or your places' coordinates lets you easily copy coordinates in any format. - Measurements can now also be made using the bubble level. - 160+ new waypoint icons.
