Have you climbed to the top of a mountain and want to know your current elevation? Or are you out and about and wondering how far you still have to go? Altimeter shows you your elevation. It’s also conveniently available on your Apple Watch! What if you want to mark points along your route so you can find them again later? No problem! With Altimeter, you can name and tag locations with an icon and navigate back to them later. This works on your iPhone, iPad, and Apple Watch. Altimeter is free, ad-free, and doesn’t track you in any way. Some features are available only to supporters, but anyone can try them for free for a few days. The basic features are freely available and will remain so. If you have questions or comments, you can submit a support request within the app. Features - Elevation in meters or feet with high accuracy - Locations in multiple coordinate systems (International, Swiss, UTM, MGRS) - Save locations as waypoints for later and organize them into folders. - With Augmented Navigation, you can see exactly where your destination is right in the camera view. - The Radar view shows you all waypoints in your vicinity, even in 3D. - Share your waypoints even without an internet connection. - The combined view shows you elevation and location at a glance. - Light/Dark Mode, color or monochrome - iPhone, iPad, and Apple Watch Altimeter uses your device’s GPS chip to determine your elevation and location. To maximize battery life, the chip is only activated when the app is open on your iPhone, iPad, or Apple Watch. This means there is no background activity, and your location is not stored. Note Accuracy depends on GPS satellite reception. Reception is limited indoors. Continuous use of GPS can significantly reduce battery life.

About

Compass Toolkit

Features
Read full description

Compass Toolkit puts a whole outdoor navigation kit in one beautifully crafted app. At its heart is a stunning brass-amber marine compass — a real, gorgeously rendered instrument that shows heading, cardinal points and true vs magnetic north, so orienting yourself feels like holding a fine piece of gear rather than reading a flat dial. Around it sits everything an explorer needs: precise GPS coordinates in DMS, decimal or UTM you can copy and share; live altitude and barometric pressure; a digital bubble level for setting up a tripod, hanging a shelf at camp or checking a slope; sun and moon rise and set times with golden-hour and blue-hour windows for photographers; and waypoints you can drop, name and see together on a map. When you find somewhere worth remembering, a share-location card turns your spot into a clean, sendable snapshot. Compass Toolkit works offline — the compass, coordinates, altitude, level and sun & moon calculations all run entirely on your device with no signal needed; only the waypoint map loads Apple map tiles when you happen to have a connection. It is 100% on-device with no account and no tracking: your data stays on your device and is never uploaded to us or anyone else. Native and universal, it's designed to feel just as at home on iPad as on iPhone.
