Comments on Ham Solar | HAP Chart for Android

★★★★☆ Mike Naylor · Jan 30, 2021

I use it at least once a day to check band openings, I wish I knew more about the other numbers though.

★★★★★ David Dietrich · Dec 16, 2020

A "must have" for hams! It's a no frills' app, just straightforward information you need to know about solar conditions. The same graphic is available online at various sights, but having the app is so much easier. I use it to determine whether I am going to jump on the radio and operate, or if it is better to go do something else as my free time is limited.

★★★★★ C. Matthew Whalen · Apr 7, 2021

Simple app that displays the propagation chart. Does exactly what I need it to do.

★★★★★ Indrid Cold · Jul 5, 2021

This is a wonderful app to know when shortwave propagation is high, so I can listen to Nagoya, Japan from Saskatchewan, Canada. I can also listen to over the horizon radar, the ever dwindling amateur radio operators, ships at sea, and military shortwave operations. This is the most concise app for the size.

★☆☆☆☆ Stephen Sutker · May 17, 2022

Thank you for your quick response to my post. I truly appreciate your time and interest. To detail my issues; I have had your HAM SOLAR app for quite a while and really like it. Recently the app just stopped working. By stopped working I mean it would not load beyond the initial splash screen showing two globes, the refresh and donate buttons. After rebooting my phone several times with no joy, I deleted the app and reinstalled it with the same results. I also tried to reconnect from a different location on the other side of town with the same (or lack of) results. Additionally, While reloading the HAM SOLAR app, I saw another of your apps, HAM CONTEST, which I thought was a great idea. I downloaded the app and found the exact same issues noted above. As you might imagine, this has been very frustrating when I also have the HF PROPAGATION app loaded on my phone, and it is, and has been working FLAWLESSLY for months. Thanks again for your time and the quick response '73 Steve Sutker K4LEG
