The Merlino app is able to read and write the parameters of CPA Merlino WiFi iOT devices: chlorine generators, devices for reading and regulating pH and Rx, for the management of heaters, whirlpools, pumps, RGB lamps. The devices are seen as WiFi Access Points. The app user must select the WiFi of a device in the iPhone settings before opening the app and connecting to it. The WiFi device must be close to the iPhone, at most a few meters. The app allows you to simulate the connection to a device, if the device is not physically available, by turning off the iPhone's WiFi before running the app, in this way it is possible to verify all the app's functions.

Verdict
The clearest difference is update cadence: HPOWER at every 3 months against Merlino's every 7 months. Merlino's advantage is iOS requirement (14.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.
