At the outset, I am a frugal (cheap) individual.
As an alternative to iAnything devices, there is an Android application that has me blown away. It is Avare and is installed on 3 devices I own. I paid less than $200 for each of these devices and Avare runs on them all.
1. A LG2 mobile phone
2. A 8" Samsung Tab8
3. A 10" Acer Iconia A3
Avare is a totally free application and updates are free. Chart downloads are free. If you run android devices I suggest you try it and see if it works for you. Did I say it is FREE? It has been developed and is very actively maintained by experienced, active pilots. Many are commercial certificated. There is a forum where users may offer suggestions, request changes/additions and report any anomalies. I am a student at this time and am not intending to use it during this phase. This application and the hardware it runs on are NOT certified. I do think it is an excellent backup to paper in the cockpit. ADS-B in is also supported
FWIW
