Read your exact position in every format at once — decimal degrees, DMS, DDM, UTM and MGRS — and copy any of them with one tap. YOUR POSITION, EVERY FORMAT • Five coordinate formats shown together on the first screen • Tap a row to copy that exact string for a map, a message or a form • Horizontal accuracy and vertical accuracy, shown separately • Altitude above sea level, ground speed and course over ground • Metric, imperial (feet, mph) or nautical (feet, knots, nautical miles) When the phone has no valid altitude or you are standing still, the app shows a dash instead of a made-up 0 m or 0°. SAVE AND FIND PLACES • Save here: store the current fix under a name you choose • Average here: collect up to 30 fixes over 30 seconds and save the mean, with an estimated uncertainty that never claims to be better than the fixes it came from • Rename or delete saved places at any time • Go to a saved place: distance, bearing and ETA, with an Arrived badge within 100 m. The arrow follows your GPS direction of travel, so it works while you are moving — it is not a magnetic compass • Export all saved places as CSV or GPX PREDICTED SATELLITE SKY A polar sky chart shows where the GPS, GLONASS, Galileo, BeiDou, QZSS, NavIC and SBAS satellites are above you right now, calculated with the standard SGP4 model from public orbital data (CelesTrak) for your position and time. The data refreshes weekly, a bundled copy works offline, and the date of the orbital data is shown under the chart. This is a prediction and the app labels it that way. iOS does not give apps per-satellite data, so the chart does not show which satellites your iPhone is receiving or using. A satellite list sorts everything by elevation. LOCK SCREEN While the app is open, a Live Activity shows accuracy, altitude, speed and course on the Lock Screen and in the Dynamic Island. The app does not track location in the background, so the card marks itself PAUSED instead of leaving an old reading looking current. GOOD FOR Hikers and paddlers checking a fix before relying on it · search and rescue, scouts and land navigation with MGRS or UTM · geocaching · drone and paragliding pilots · anyone who needs to send an exact position Readings come from your phone's own location services. Accuracy depends on the device and on a clear view of the sky. Available in 30 languages.
HoleCopy
Read full descriptionHide full description
Replacing a bracket, a hinge or a speaker plate? The holes are the hard part. Measuring them one by one with a ruler stacks up error until the last hole is off. HoleCopy copies the pattern instead of measuring it: lay the old part on the reference sheet, take one photo, and get every hole center and diameter in real millimetres. HOW IT WORKS 1. Print the A4 or US Letter reference sheet at 100% 2. Lay the old part on the sheet and take one photo 3. HoleCopy squares up the perspective and detects round through-holes 4. Check the result on screen: move a center, resize a hole, add one the camera missed, delete one it invented 5. Export a true 1:1 PDF or SVG, tape it to the new material and drill WHAT YOU CAN DO BEFORE EXPORTING Photographing the part, perspective correction, hole detection, editing and the output preview all work with any part you try. You can see whether HoleCopy reads your part correctly before you export anything. WHAT UNLOCKING EXPORT ADDS Saving, sharing and AirPrinting the actual-size PDF or SVG, as often as you like. That includes patterns larger than one sheet, split across pages with overlap marks and alignment crosses, ready to tape together. BUILT FOR THE WORKSHOP - Mirror the template for the back side of a part - SVG export for vector programs - A 100 mm and 1 inch check bar on every page, so you can confirm your printer did not scale it - Everything is processed on your device; photos never leave it WHO IT IS FOR Furniture repair, woodworking and metalwork DIY: brackets, hinges, handles, table legs, speaker cabinets, control panels, car or motorcycle mounts, gasket and flange hole patterns. BEFORE YOU DRILL HoleCopy works with flat parts and round through-holes of 3 mm and larger, when the part and the reference sheet fit in one photo. It is a positioning aid, not a guarantee of precision: check that the printed bar measures exactly 100 mm and drill a small pilot hole first when it matters. Not intended for safety-critical parts.

Verdict
The clearest difference is price: GPS Status & Satellite Sky at Free against HoleCopy's $1.99. GPS Status & Satellite Sky also leads on in-app purchases (none vs 1) and update cadence (every 4 days vs monthly). HoleCopy's advantage is ads (none vs shown). On device support and iOS requirement there is nothing between them.
