Discover and control what data is collected about you by Internet of Things (IoT) technologies. The IoT is everywhere. It consists of a myriad of devices and technologies that collect data about us - from cameras with facial recognition, to smart speakers that record what we say, or sensors that track our whereabouts. The IoT Assistant app helps you discover what data is being collected about you and how it is used. This includes who is collecting it, who it is shared with, and whether there are any privacy controls. New privacy regulations around the world require people who deploy IoT technologies to disclose their data collection and use practices and to also give us some control over these practices such as opting in or out of them. The IoT Assistant app provides users with a single interface through which they can discover IoT data collection around them and access available privacy controls. The IoT Assistant app also allows you to receive customized notifications about data collection and use practices you want to be notified about and control the frequency of these notifications. An IoT portal associated with the app (https://www.iotprivacy.io) is available to also publicize the presence of IoT technologies ("IoT resources") collecting our data, whether you are the administrator controlling that technology or a volunteer contributor. Once you have defined an entry for an IoT technology through our portal, IoT assistant app users can discover this IoT technology and its data collection and use practices.

App will find all hosts in your home network or in selected IP range. It can be used not only to know who are using your WiFi and learn more about every device, but also for solving professional tasks. By installing ScanNet - Network Scanner on your device, you get a handy and easy-to-use network scanner that does not require special knowledge when working in the default mode. Following functions and capabilities of the application will be useful for administrators and IT specialists: 1) The ability to check ports right during the search for hosts. Filtering by open ports allows you to quickly find the server you need on your network. 2) IP scanner supports 4 scan modes - arp read, icmp ping, udp ping, dns request. The ability to manually set a DNS server significantly expands the functionality of scanning private networks. 3) A wide range of settings allows you to manually set both the scanning mode and the used methods of name resolution - currently supported by DNS, mDNS, netbios. 4) Advanced search in the list of found hosts - you can search both by all available information, and by address, name, open ports. 5) Personalization - the ability to change the picture and the hostname displayed in the interface. This function requires binding to the WiFi network name for the best performance. In order for the application to get the network name, access to the location will be requested. 6) The function of saving a list of found devices and opening it for study later. 7) The program includes network utilities familiar to every administrator - ping, tracerout, port scanner. Premium access allows you to access them directly from the device information screen. In the free version, all utilities are available for calling from the application menu.

Verdict

IoT Assistant's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, update cadence and device support there is nothing between them.
