Face it. We've all got stuff, and some of it matters. Keeping track of it isn't easy though, so we never get around to making that inventory, and then when we need it we wonder why we never did. Solution? You found it. With the Possessions App you can quickly and easily inventory the things that matter to you. * Store multiple photos for each recorded item and arrange and update them as needed. * Unlimited-length free-form text descriptions. * Add new item types on-the-fly. * Add new item locations on-the-fly. * Easily email and print your item photos. * Use search to find your items quickly by name. * Use category, type, and location filtering to narrow your focus. * Use sharing functionality to email and/or print item and property contents in report-style output; share attached images to any supported sharing target. * Expose summary information for Real Estate items directly on the device Home Screen with Property Summary widgets. * Use Data Export to create a backup of your entered data within a single ZIP archive for subsequent restore actions and/or moving data to another device. Supported categories include Real Estate, Vehicles, Stored Items, and Property Contents, with an extensive list of pre-defined types in each. Get the Possessions App. Get organized. Be prepared.
ViDiLabs Calc
This app calculates necessary camera lens focal lengths and object distances for optimal pixel density, aiding in compliance with surveillance standards. It also estimates storage capacity for video recordings and helps analyze moving object blur for clearer image capture.
- Calculate required focal length and object distance
- Determine required storage capacity
- Pixel density calculation for identification and recognition
- Database of commercially available sensors
- Manual entry for custom variables
- Moving object blur analysis
- Pre-set pixel densities for common projects

The ViDi Labs calculator helps you calculate the required focal length lens on a camera, or suggested distance to an object, in order to achieve the required pixel density (read clarity), compliant with various standards. It also helps you calculate the required storage capacity for a given number of recording days or minutes (in case you need to export an incident on a USB flash drive). It consists of two sub-applications, one called Visual and the other Digital. Many surveillance standards or tenders would specify cameras in particular locations in a project so that facial identification or recognition is achieved at the particular area. To comply with such tenders is not easy because pixel density calculation depends on the sensor size, the focal length of the lens and the distance to the object, all interdependent. The ViDi Labs calculator has all the right formulas to do it for you. It contains a database of all commercially available sensors, from the smallest up to the large format cameras (currently 102MP). All you need to know is the sensor your camera uses. With the latest version 2.0 of this app we have introduced manual entry of any of the variables (by double-tapping a window), including distances or focal length that are not in the scrolling picker data-base, or perhaps you use an "unusual" or new sensor size. In the Pixel Density area of the pre-set buttons on the right hand-side we introduced the correct pixel densities for Face Identification (FI), Recognition (FR) and Inspection, as per the Australian Standard corrigendum document for the IEC 62676-4: 2015. In this version, the FI is now 350pix/m, instead of 250pix/m, and the FR is 175pix/m instead of 125pix/m. Similarly, for the Face Inspection we now have the value of 1400pix/m, instead of 1000pix/m. These corrected numbers will help you design a better system. You can still enter, however, any value you desire by scrolling the window or manually entering by double-tapping. In addition to the "facial" pixel densities pre-set buttons, we have also introduced pixel densities pre-sets for common projects such as Licence Plates Recognition (LPR), money and playing cards. Please note that these values are from our own testing and experience, and they do not exist in any standard as such. The CCTV industry is not the only field of use for the ViDiLabs calculator, because this app can be used by anybody with a digital camera, be that in photography, cinematography, or in machine vision, as it can help find the best lens, distance and camera settings for the clearest image. In the same Visual section, the ViDi Labs calculator also calculates moving object blur as they are recorded with various exposures. Such calculations are first in the industry and could prove extremely useful in systems used for automatic face recognition, vehicles automatic licence plate reading, reading the roulette wheels winning numbers and all other moving objects that need to be seen more clearly. In the latest v.2.0 we introduced yet another new and unique calculations which considers the angle of the object motion relative to the optical axis. Under the Digital sub-application, the ViDi Labs calculator also calculates the recording storage capacity for a given number of cameras, chosen length of recording, percentage of VMD and compression. Users can also enter the type of storage required (RAID type) and the calculator will advise how many hard disks are required to achieve the chosen number of storage days. For the first time in the surveillance industry, it can also indicate the visual quality of the chosen compression by showing a simulation of the ViDi Labs test chart for the chosen compression (H.264 or JPG). Last, but not least, in the v.2.0 update, we have introduced calculating of the storage needed of a short event, typically lasting a few minutes, which needs to be exported to a USB flash drive for for further analysis by third party or Police for example.

Verdict
The clearest difference is price: Possessions at $0.99 against ViDiLabs Calc's $18.99. Possessions also leads on rating (3.7 vs 3.0) and ratings volume (3 vs 1). ViDiLabs Calc's advantage is iOS requirement (12.0 vs 17.6). On update cadence, ads, in-app purchases and monetization model there is nothing between them.
