But this power comes at a cost; you must be a hardcore DIYer or an installer as the power is in JavaScript which one uses to get feedback and extreme control. The support is great too with a dedicated forum to ask and learn. This review is only about App and its related builder (that you download from CommandFusion site); naturally to IP, Serial or IR control some equipment you need hardware too. ### 5/5 — Impressive *2014-01-17, version 4.0.288* I don't write many reviews let alone 5 star. There are no real alternatives to this if you need to create anything more than a basic remote control. The support forum is excellent and the devs are very responsive. What separates this app from others is the ability to use JavaScript for complex macros and automation. I've paired this with the iTach IP2IR from Global Cache and the combination is controlling a fairly complex AV set up. ### 5/5 — Very powerful *2012-06-28* Great app and very powerful. ### 5/5 — Great! *2012-02-25* Excelent app! ### 1/5 — Pricey! *2012-01-29, version 4.0.196* Not really free, you need a licence for each controller! £109! ## Frequently asked questions about iViewer 4 ### What is iViewer 4 used for? iViewer 4 is a home automation app that allows for two-way remote control of any hardware or software capable of TCP/IP or UDP communications.
