"objManager" is a Wavefront .OBJ file viewer (3D models with .obj + .mtl file extension). With "objManager" you will have the ability to: 1) save your 3D models on your mobile device 2) display the 3D models in any times and under any working condition (no Internet connection is required) 3) create images of your 3D model using the HD rendering procedure (with anti-aliasing and image enhancement filters) 4) choose the background color 5) move the light where You want in the 3D world The software does not need an internet connections: each 3D model is stored in your mobile device (using the technology "iTunes File Sharing" or "Open In") and can be read and visualized by objManager. objManager works like the integrated image viewer of the device, you can then: - ZOOM IN / ZOOM OUT the 3D model by dragging two fingers on the screen or using the ZOOM controls - Rotate the 3D model (ROTATE TOOL) by dragging a finger across the screen - Move the 3D model (PAN TOOL) using the PAN controls - Load the 3D model (from the obj files archive of objManager; 3D models are displayed in alphabetical order into the "obj Archive" of "objManager") - Save an infinite number of 3D models into the "obj Archive" of "objManager" (until the physical memory of the device is ended) - Share 3D models ( .obj files ) with File, Google Drive, DROPBOX, iFolders Safe, etc... or from iCloud Drive or other installed apps (cloud sharing: OUT) - Import 3D models from the web links, email attachments, File, Google Drive, DROPBOX, iFolders Safe, iCloud Drive or other installed apps (cloud sharing: IN) Compatibility with: 1) Maya 3D 2) Blender 3) 3D Studio 4) Finger3D 5) FingerCAD 6) Unity 7) 3D modeling software with export to .obj feature (or .obj + .mtl) If "objManager" is not enough for your aim, try the complete 3D modeler: Finger3D. "objManager" can also be used to view the .obj + .mtl models created with Finger3D in full screen (with orientation: Portrait).

The RF Haversine Lite (RF Propagation and Analysis Tool) bring our experience gained on Radio Propagation to the mobile market. RF Haversine Lite is an application for iPhone and iPad with which you can quickly calculate a radio link budget: - Calculate simple radio link budget - between tho locations - Check the two locations on Map - Calculate Fresnel Radius - Calculate Earth Bulge - Calculate attenuation loss for O2 and Vapour (Vapour Density 7.5g/m3) - Calculate Fade Margin for different radio availability - based on K region (Rain Fall region - ITU-R PN.837-1) Option: -Email the radio link report and KML file -Open KML file in other compatible application Full Version: RF Haversine is the first application for iPhone and iPad with which you can quickly check: - Check the Terrain Profile between two locations (elevation provided by a public server) - Calculate radio budget based on terrain profile and radio parameters - Calculate DIFFRACTION LOSS (calculating only for the first major obstruction from profile) - Import new links from CSV - You can change the default values for the radio parameters - For the new links you can use your current location, choose from an existing one (History) or select a point on the map All you need - The tool requires an internet connection for terrain profile. The Lite Version don't Offers In-App Purchases (You can't upgrade to the Full Version)! The RF Haversine analysis covers the range of 35MHz- 38GHz. No training is required and the grip is immediately. The information and the results provided on this software are not a substitute for professional radio planning tool!

Verdict
The clearest difference is update cadence: RF Haversine Lite at every 3 months against objManager's every 38 months. RF Haversine Lite also leads on device support (3 vs 1) and iOS requirement (12.0 vs 16.6). objManager's advantage is price ($0.99 vs $1.99). On ads and in-app purchases there is nothing between them.
