The Geosensors app is the companion to the Geosensors Logger hardware that together make up a powerful geophysical surveying tool. The logger connects to an electromagnetic sensor and an external GPS device in order to provide all the information necessary to carry out a successful geophysical survey. The app connects to the logger via WiFi and allows a surveyor to monitor live data from the EM sensor, set-up and record a new survey, transfer completed survey data to the app, view the summary details and then email the data for further processing on a desktop computer. Note that to get the best use out of this app, it must be connected to a Geosensors Logger. Please contact us if you need to purchase a logger and/or EM sensor. Features: - Connect to a Geosensors Logger via WiFi - View EM and GPS data as it is being recorded to the logger. GPS data is shown on the map. - View auxiliary data from the EM sensor such as battery level, tilt and rotation angles and temperature. - Resume incomplete surveys - Use the terminal to modify internal EM sensor configuration settings - Modify the logger configuration settings such as sensor baud rates, device name, WiFi security - Download previous surveys from the logger to the app. Downloaded surveys can reviewed in app and then emailed as an attachment

Verdict
The clearest difference is in-app purchases: Geosensors at none against RadMonJP's 6. Geosensors also leads on iOS requirement (10.3 vs 26.0). RadMonJP's advantage is update cadence (every 8 days vs every 3 weeks). On price, ads and device support there is nothing between them.
