[Seeking advise on 5w HT vs. 15-20w mobile for repeaters]

I noticed their Ham version is but their site says the GMRS version is 5 watts. Does this app change that? 

First all the TD-H8 are the same, they are just running different firmware modes.  You can change this mode by holding PTT plus either Asterisk (Ham), Zero (GMRS), or pound (fully unlocked) as you turn on the radio.

If you fully unlock it it defaults to medium power being 5 watts and high power being 10 watts on GMRS frequencies

Even in GMRS mode though, the power configuration app can indeed be used to change it to 10 watts.

You guys go ahead and keep debating which GMRS HTs put out the most power. I'm going to lunch. Lemme know if you ever settle it. On second thought, no. 

We aren't debating anything, we are passing on information on how different radios work.  Why comment if you have nothing useful to add?

I don't know what you have in your HT collection, but every one of mine is limited to five watts. 

The Tidradio TD-H8 can put out close to 10 watts, they have an app to tune the output at different power settings and frequencies too.
