StratLogger vs Chocorua Map
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
StratLogger
This app helps geologists construct stratigraphic columns digitally, replacing traditional field notebooks. It logs location, links photos to descriptions, and exports data for analysis. Optional tools enhance student learning in the field.
- Construct stratigraphic columns
- Log sedimentological and stratigraphic information
- Automatically log geo-location data
- Link images to lithologic descriptions
- Export stratigraphic column as JPEG
- Export layer records to CSV
- Optional pedagogical tools for student learning

StratLogger is an application for use in constructing stratigraphic columns and can serve as a complement to, or replacement for, the traditional paper geology field notebook or stratigraphic column drawing sheets. StratLogger integrates the iPad’s GPS, camera, and data management capabilities to allow geologists to record sedimentological and stratigraphic information for successive layers in a stratigraphic column, automatically log geo-location data, and link images to each layer’s lithologic description. StratLogger can then export a real-time, app-produced stratigraphic column image as a .jpeg file as well as each of the layer records to formatted .csv files for easy integration into digital drawing and analysis applications. The lithology photographs are also exported and indexed with the name of the appropriate measured layer. StratLogger integrates an optional set of pedagogical tools, in the form of feedback/hypothesis questions, intended to foster increased student learning while in the field. The answers to these questions are recorded to track how data acquisition through section relates to how the user interprets the paleoenvironment of the study section.

The Chocorua Map app is a mobile guide to trails and points of interest (POIs) in and around Mt. Chocorua and its eponymous Lake, especially the area preserved, directly or indirectly, by the Chocorua Lake Conservancy (CLC). If you allow the app to use your location (e.g., GPS), you can find and track your position on the map. The app contains abundant information on trails, including how long it should take at a given pace, as well as historical and geological points of interest.. Measure distances and compass bearings by tapping and dragging on the map. Publicly accessible lands of different types are shown with transparent color overlay. The background map was rendered from LiDAR topography and has a resolution of 1 meter. The app's built-in POIs describe sites of historical interest, unique landscape features and how they developed, and features of geological and ecological significance. The user may enter their own POIs and attach photos to them; all user-entered information remains private to user's device. The user can share their POIs with other people or apps via the standard iOS Sharing Panel. The app is completely self-contained: No internet connection is necessary. Furthermore, user data is NEVER uploaded automatically to the Internet and can never be seen by the app programmer, CLC, or any other third party. This app is for educational purposes only and should not be used as a sole source of navigation. The CLC and the author are not responsible for the accuracy of any of the information presented by this app.
