Correct Altitude establishes your position using data from at least twelve GPS satellites. This app shows the altitude at your current location, and enables you to take altitude-and-date-stamped photographs. Hikers usually turn off their iPhones on mountain trails because of the poor signal. When turned on, the iPhone GPS will try to determine the current location with data from three GPS satellites; however, these co-ordinates are still inaccurate. CorrectAltitude triangulates position with a large number of GPS satellites in a 5-minute period enabling an accurate determination of altitude. The app automatically continues triangulating position by polling GPS satellites, and informs you when it has established a location accurate to within the tolerated range of error. The default for this range is 5 meters (approximately 16 feet). As an add-on function, it can display where you are (if the place has a name), and this can be useful for contacting rescue services in emergencies. CorrectAltitude has been tested on hiking trails in the Himalayas! Here is an example of an altitude-and-date-stamped photograph. The photograph is taken at the maximum resolution of your phone's camera and stored. GPS information is discarded. If the Notify mode remains set to "ON", you will continue to get updates on altitude every five minutes. To conserve the battery and stop repeated updates, you may prefer to set Notify mode to "OFF" after you have determined your altitude.

Your speed, with character. Speed-O-Meter Pro brings glowing Nixie-style digits and a brass-trimmed analog dial to a GPS speedometer for iPhone and Apple Watch. See your speed at a glance, follow your trip statistics, and keep the final numbers when you finish. CHOOSE YOUR DASHBOARD Switch between digital and analog displays, choose mph or km/h, and use light, dark, or system appearance on iPhone. Portrait and landscape layouts keep the dashboard readable in either orientation. KEEP YOUR TRIPS Start a trip, pause when you need a break, and resume later. Finish while recording or paused to save a summary of distance, recorded time, average speed, and maximum speed. Browse up to 100 saved trips on each device and share completed summaries from iPhone. BRING IT TO APPLE WATCH Choose an analog dial or a digital dashboard with speed, trip distance, recorded time, temperature, and humidity. Record with Watch GPS and synchronize trip state and recent completed summaries with your paired iPhone when connectivity is available. TRIP CONTROLS ON APPLE WATCH Start: switch to the digital dashboard using the style button at the bottom right. Tap either the trip distance or elapsed-time tile to start a new trip when none is in progress. You can then switch back to the analog dial while recording. Pause and resume: in digital mode, tap either trip tile to pause the current trip. Tap again to resume the same trip with its existing statistics. Trip details: on either dashboard, tap the clock with a circular arrow near the top left to open Trips, then select your current trip. Scroll down for Pause trip or Resume trip and Finish and save. In digital mode, you can also press and hold either trip tile to open the current trip's details directly. Finish: tap Finish and save in the trip details to end the trip and keep its summary. You can finish while recording or paused. To review it later, open Trips and select it under Saved Trips. Start your next trip from the digital dashboard. MORE AT A GLANCE The iPhone dashboard includes a compass, GPS status, temperature, conditions, humidity, rain chance, and wind. Choose Celsius or Fahrenheit separately from speed units. Weather is provided by Apple Weather when a location and network connection are available. PICK UP WHERE YOU LEFT OFF An interrupted locally recorded trip can reopen paused with its saved statistics. Trip summaries are stored on your devices; they do not include a recorded GPS route. Trips started on Apple Watch can record in the background. Pause stops recorded time and distance but keeps Location ready for remote Resume, using some battery. Finish ends background Location. After an app restart, open the Watch app once to restore Location before resuming the recovered paused trip. iPhone trip recording requires the iPhone app to remain active. GPS accuracy depends on your device and reception. The digital display shows zero without valid GPS speed; check the GPS status indicator. All three tubes stay visible. The device where you start a trip remains its recorder. Keep both apps updated to control it from the other device. Buttons show progress while waiting for confirmation, including when the Watch is in the background. Delivery may be delayed; unprocessed requests expire after 30 seconds. If confirmation fails, check the recording app before retrying, and open it if prompted. The Apple Watch label beside the iPhone's speed-unit selector identifies the trip recorder; a muted dot means its latest update is delayed. A temporary disconnection does not transfer recording to the other device. The app is free with ads. No ads appear on the Apple Watch dashboard.

Verdict

The call

The clearest difference is review sentiment: Speed at 100% against CorrectAltitude's 0%. Speed also leads on price (Free vs $0.99) and update cadence (weekly vs every 8 months). CorrectAltitude's advantage is ads (none vs shown) and iOS requirement (13.1 vs 17.6). On in-app purchases and device support there is nothing between them.
