ContriApp is the world first application using Bluetooth® protocol being able to read and write parameters of a safety light curtains. It is intended for use with safety light curtains from Contrinex and is the tool to change the parameters of the device. It can also read diagnostic data and can be used as a maintenance tool. ContriApp targets users who need to configure the light curtain for installation (initial setup and configuration) or need relevant information on the current status and operation of the light curtain (maintenance, analysis, etc.). The application can be used in different modes (observer, maintenance or specialist), thus enabling different views and accesses to the light curtain. In observer mode, parameters can only be read and no change can be done. In specialist and maintenance modes, the user can access part or all of the parameters for read and write function. Those modes are protected by a password to allow the right users for access. A subset of these parameters is presented below : BEAM CODING Beam coding can be used to prevent cross talk between one pair of light curtains and another mounted in close proximity. It is important to set the same beam code for the sender and the receiver. An LED indicator on each light curtain shows which beam code is selected. Three different codes can be selected through the application. (BC_1) EDM (EXTERNAL DEVICE MONITORING) EDM is the abbreviation of External Device Monitoring. This function allows the user to enable or disable EDM functionalities on the light curtain. (disabled) START OPTION Tap here to select a manual or automatic start for the light curtain. (automatic) RESTART OPTION Tap here to select the manual or automatic restart interlock. The restart interlock is either enabled (manual mode) or disabled (automatic mode). (automatic) On top of these options, other information are also available in read only. A subset of these information is listed below : - DEVICE STATUS - STATUS OF BLUETOOTH® - LAST UPDATE BY - DEVICE NAME - FIRMWARE VERSION - SERIAL NUMBER - BEAM ALIGNMENT More information and documents can be found on Contrinex's website www.contrinex.com

Verdict

The call

The clearest difference is rating: RealVNC Viewer at 4.8 against ContriApp's 4.0. RealVNC Viewer also leads on ratings volume (15K vs 1). ContriApp's advantage is review sentiment (100% vs 72%) and update cadence (every 3 weeks vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

RealVNC Viewer holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: RealVNC Viewer has 15K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 72% of RealVNC Viewer's written reviews are positive against 100% of ContriApp's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

RealVNC Viewer ships an update every 2 months, ContriApp every 3 weeks. The most recent releases landed on October 28, 2026 and October 14, 2026 respectively.
