MapProjectionDemonstration vs entanglement entropy
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
MapProjectionDemonstration
Explore and understand various map projections with this educational tool. It visually demonstrates how spherical data is converted to flat maps, allowing customization of central latitude and longitude. Formulas for conversion are also provided.
- Illustrates map projections
- Categorizes projections (cylindrical, conic, azimuthal)
- Demonstrates 31 projection types
- Customizable central latitude and longitude
- Includes conversion formulas
- Visual conversion process

Map Projection Demonstration This app illustrates a variety of possible map projections. Map projections fall into three general categories: cylindrical projections, conic projections, and azimuthal (or polar) projections. Each category contains several different types of projections. The app demonstrates the creation of maps in 31 different projections, and allows the user to choose the central latitude and longitude for each map. The formulas that are used to convert locations on the surface of a sphere to locations on a flat map are included. There is also a visual demonstration of the conversion process for each of the map types.
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.

Verdict
The clearest difference is iOS requirement: MapProjectionDemonstration at 16.4 against entanglement entropy's 18.0. On price, ads, in-app purchases and device support there is nothing between them.
