Hi, I have the following on my phone which are free-Apps or have low priced extentions. i-Rover .... Maidenhead .... Hamlogger ....Morse-it.I am no reviewer but I have found some 'aids to navigation' in these apps with the latter being helpful in getting CW back into my head after a long layoff. The iPhone compass is handy too when operating an Armstrong rotator when out in the hills as /P!!! 73s Dave
I don't have much Radio related Apps on mine, although I agree Maidenhead is very useful especially when mobile or portable. I also have DL8MRE's icluster which just about keeps me sane when away from home UKSMG#217
