GPS Diagnostic: Satellite Test App Reviews

This is a great tool for ensuring my other GPS-based apps are giving me valid information. It is worth the price many, many times over! Thanks so much for your perseverance in creating this! I wish I had had this app back in my earlier days when I was flying Rescue missions and working as a flight test engineer. Invaluable!! Thanks again!!

I successfully used this app to confirm the quality of the reception of satellite data. Months later I find myself in Japan on the Shinkansen “bullet” train wondering how fast we are traveling. This app provided the answer. In case you are wondering, we were traveling about ~275 km/hr!

Works great now.

Now I know why navigation says to turn in 50 feet after I was supposed to have turned!

Easy to use and not more complex than necessary. Great for sending my location.

It works perfectly.

Great product. Helped me diagnose some gps questions relating to a website we were developing. Very simple to use. Wish the Lodestone graph had one more bar to see when I have a 5th satellite.

Got the app and had a question. Emailed David and he responded immediately to help me figure out my GPS issue.

With the recent ending of CDMA as a time source for NTP servers we had to purchase new units that sourced time via GPS. Running into signal issues this app helped me locate a area where GPS signal was attainable. It’s a simple app but did everything I needed perfectly.

Excellent app, love it, and recommend it!

Inside my house 15 feet away from the window this shows I pick up 4 + Satellites. It’s nice to know whatever map app I use I can tell I’m getting a correct reading (location). I recommend this app.

Incredible app! Questions for dev: Will BeiDou support be added? Why is a question mark showing next to GPS? Why is it blank next to cellular?

Works great but I’d love to see the signal strength of all satellites being received. Not just the first 3.
