Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Jake for stratigraphy
Read full descriptionHide full description
Jake makes measuring a stratigraphic section a snap. Place the device on a bed, and with a tap of a button, record your dip and dip direction. Arrows tell you when your device is pointed in the direction of dip and inclined at the correct dip angle. No more futzing with hard-to-read clinometers and compasses!
entanglement entropy

This app represents entanglement entropy for a pure bipartite state of the composite system. The entanglement entropy is von Neumann entropy for the reduced density matrix.
