Altitude Plus vs TideHelm

The Altitude Plus app lets you know the altitude of your location. However, you can find out the altitude of any point in the world on the map. You can learn the altitude of high mountains, cities or your location. We are using two different APIs. You can change the api on app settings for a more professional use. This application needs your location information and internet to work. In this application, you can learn the altitude of your location completely free. However, in order to learn the altitude of each point on the map, you need to make a one-time in-app purchase. We get your location data and altitude data of your location from Apple. Open API is our default API. It is completely free. However, it does not provide altitude data as detailed as the Google API. Google API gives detailed altitude data. In order to use Google API, you need to get API from google developer website. This may charge by google. When you select google api so that you do not pay high fees, it only pulls data when you click on the annotation on the map. We do not collect, use or share any of your data and location information. Enjoy!
