FieldMove Clino Features: FieldMove Clino is a digital compass-clinometer for data capture on your iPhone, designed for simplicity in the field, and optimized to use the device’s GPS location and orientation sensors. This geology app will allow you to use your phone as a traditional hand-held bearing compass as well as a digital compass-clinometer for measuring and capturing the orientation of planar and linear features in the field. FieldMove Clino allows you to quickly take large amounts of measurements, making your data set much more statistically valid. You can also capture and store georeferenced digital photographs and text notes. As well as supporting online maps, FieldMove Clino also supports offline maps, so that you can import your own georeferenced basemaps and collect data while disconnected. Data can be exported as MOVE, CSV or KMZ files and then imported directly into FieldMove™, Move™ or other applications like Google Earth. Additional features: • Display geological data on an equal area or equal angle stereonet, allowing you to perform some basic statistical analysis in the field • Draw contacts, faults and outcrops on your chosen basemap to create a realistic geological map • A new expanded library of symbols for customisation of planar and linear features • KMZ export, view your data in Google Earth A more in-depth guide is available on our website: http://www.petex.com/products/move-suite/digital-field-mapping/ NOTE: FieldMove Clino for iPhone will scale up to fit on the iPad and iPad mini. FieldMove Clino is a Petroleum Experts geological field mapping app designed for forward thinking geologists utilising digital data collection. --------------------------------- * The use of GPS devices and smartphones as navigation aids. * Global Positioning System (GPS) devices are commonly used to aid navigation, having grown in popularity over the past decade. Over the last few years, this has extended to smartphones and digital compasses, which are often equipped with GPS functionality. GPS is a valuable aid to navigation during fieldwork, although it is important to keep safety at the forefront, and we draw your attention to the advice given by a number of mountaineering councils: “Everyone heading into the hills needs to learn how to read a map, and be able to navigate effectively with a paper map and traditional magnetic compass, especially in poor visibility”. Petroleum Experts will accept no liability or loss, resulting from the use or misuse of this product.

Verdict
The clearest difference is in-app purchases: FieldMove Clino at none against LetsGeo's 1. FieldMove Clino also leads on iOS requirement (12.0 vs 18.6). LetsGeo's advantage is update cadence (weekly vs every 2 months). On price, ads and device support there is nothing between them.
