According to the developer it will work on the HTC Evo 4G.
+1 I sent the guy an e-mail and got a reply back in ~2 hours.
also, the developer has always answered my questions or when i had issues, beyond fast.

I did a little poking around and it seems the knock against most of these apps is the time resolution using the phones built in GPS is on the low side. For track days it may suffice, but it's lacking for autocross. An external bluetooth GPS receiver can up the sample rate. That said, I just got my Verizon Incredible a few days ago, and I'll be downloading Trackaroo today, and will bring it to this weekend's autoX.

Cleaned up the thread a bit to get rid of the newb comments the subsequent newb bashing. I left ZX-tex's original iphone lap timer link, and case vagina's original iphone question.
The major problem as far as I know is that the iPhone doesn't have "real" GPS capabilities like the droid's. Oh well, fail on my part I guess, but I'm not sure how much I'd use it, especially right now.

Shortfalls with the built-in GPS function on most any cell platform/OS can be solved with an external bluetooth GPS. In fact that is what most do (what I have done/will be doing) since the external ones have much faster refresh rates. The lap timer software packages I have seen so far are set up to use external GPS data.
The external GPS also helps with phone placement since you can put it wherever you want as long as it can still connect via bluetooth with the external GPS.

Just a note re: External GPS
C
Bluetooth GPS Service is an add-on to Trackmaster and Dynomaster. It allows both apps to use an external bluetooth GPS that supports NMEA protocol. This is a great way to support higher accuracy and higher rate GPS units. Note: HTC Incredible, Desire, Hero, and Eris do NOT support bluetooth GPS.
Latest version: 1.3 (for Android version 2.0 and higher)

Here is the discussion on the new version of Trackmaster and extenal GPS support. It looks like it works as long as you have Android 2.0 or later.

.... but there are problems with bluetooth serial protocols on HTC Android devices, and HTC is seemingly apathetic on the issue
damn it...

I get my HTC Evo 4G phone on Friday. I'll test it out over the weekend with Trackmaster and my Qstarz external GPS and report back. If it does not work, I am returning the phone. If it does not work that is pretty lame on HTC's part to be incompatible with a relatively standard protocol.
FWIW my current HTC Hero smartphone works with the Qstarz but it is running a Windows OS, not Android.

I wonder, what was HTC thinking? Did they just not get around to it or is there a problem of some sort?
Hmmm... found this in a google Android Developer's group, something about changing a UUID and it will support SPP

a note about the internal gps. at tws last month, my trackmaster app. was accurate to 0.02 hundreths of a second, comapred to my amb laptimer. so, for that, the external gps doesn't do much. where it helps is on replay of the lap on the google map of the track. the external will show a more accurate line to analyze later. but like i said previously, if i'm trying a new line, i get immediate feedback by glancing at the logging screens sector time, if it's green, it worked, if it's red, it was slower.
