I was really surprised to see a GPS app in the top-rated list at such a low price after seeing Navigon and TomTom on there for so long. I currently use the AT&T Nav app, but I'm going to try this one today and report back how well it works for me in the Midwest USA area.
 
After testing it out a few times it seems like this app works very well. Seems pretty accurate. It does not appear to be able to keep up
the voice directions while the screen is locked. Which is a problem for me because i wanted to use this app while riding my motorcycle with headphones. Perhaps it's a bug. The music will skip from time to time while using the app with the screen locked. Only when it's locked screen
 
I will compare it to Navigon, my opinion. I am showing the positives for each, which indicates the other does not have this feature.

Motion X:
-Better looking maps, much like google maps. Easier to identify major/minor roads and street names.
-Seems to acquired the GPS signal much more reliably.
-POI are much better.
-Different styles of maps using the GPS to keep the direction north or the built in compass (which is nice when walking or getting started) and the GPS cannot get a good vector.

Navigon:
-Can drop a pin anywhere where motion X cannot.
-Has lane assist.
-Speaks street names.
-3D view seems more realistic looking (motion X just seems to "rotate" the 2D map to make it look 3D'ish.

That's all I can think of now. I like Navigon for a totally new city since the lane assist and street names are really useful. But for local areas where you have a pretty good feel already, Motion X may be better since it has a better map, better map options, and acquires the GPS signal more reliably. Also better for walking since you can use the compass and the POI's are better.

Motion X is a heck of a value, while Navigon has an OK value.
 
where can i find the source code for this? i looked on motionx's website, i find nothing

also, i found this, which seems to indicate that it is not open source:

Why would you think the source would be released?


EDIT: never mind I saw the OP said its open source. I highly doubt i would be. Most pay for apps aren't.
 
Wow.

As a strong supporter of Navigon, I'm actually impressed.

Get the street names together, then add traffic and you'll have a real contender here. Not that there isn't already a market left for this, at that price.

Best of luck to them.
 
I've been using it in North Central North Carolina (Greensboro area) for the past several days and I'm very impressed. It takes quite awhile to load, but once it's up and running it's great. Especially for the price!

I'd like a couple of, what I consider, bells and whistles like lane assist, but for $2.99 I'm not complaining.
 
I tried it out on three rides last night going from point A to B to C then back to A. Each leg was about 20 to 30 minutes each.

For some reason it could not download route data at all for trip AB.

Trips BC and CA went really well actually. Voice is a lot clearer and less muffled than AT&T's offering. I really like being able to control the iPod from within the app.

I have two main issues that are making me second guess leaving AT&T's offering:
1) When I missed a turn, it would take 2+ more blocks to recalculate my route. The AT&T app could usually do this in less than a block to get me back on track at the soonest turn possible.

2) If you get close to your destination but miss it (suppose you didn't know what side of the street it was on), MotionX will mark your trip as complete and stop giving you directions. The AT&T app would continue to tell me which direction my destination was even after passing by it until I exit the app.

I'll be on a vacation in Tampa at the end of the week where I'll be testing this app more in an area completely new to me. For now, I'm keeping both apps.
 
I'm in So. Cal and have given this app plenty of tries. It's absolutely fantastic. I love how it also has the great ipod support and turn by turn directions. It also has a SEARCH function which none of the other apps (except ATT) do.
 
Just purchased will give a review Friday night after I have time to test it out
 
Mapquest Navigator is out for .99 with TTS. Would be interested in hearing some comparisons...
 
After trying this out for a 100 mile period here is the brief version of the review I'm going to post.

Overall I think this app is great and definitely worth it even if costed more than it does.

My initial surprise was that unlike tomtom, navigon or the other apps I've tried. I was able to simply pull up any of my contacts and instantly get routed. With tomtom and other apps on the same contacts I had to make crazy modifications to the addresses to get it to work.

Accuracy has been spot on and while on the 3G network on my 3GS. I didn't have any connection issues over the 100 mile trip. There is also a small section on route where I normally lose service for a moment. During that time GPS fail or anything. Despite requiring a data connection runs fairly smooth. It's not always a constant moving triangle. However, it does move every second or so. Therefore, progress is always shown.

Core Version:

There were a couple issues with this version which I reported to dev and they replied back within an hour and said they are working on for 1.3 release.

- ETA, Time Left and distance do not update. It shows initial estimates and never changes as you approach destination.
- If you stray off course you have to manually set route again. It does not re-route you automatically (dev said will be an update button in 1.3 if u stray)


Premium Version:

Above issues in core work perfectly in premium. ETA, time, distance all update and if you stray you are re-routed.

I honestly like this app and think it's well worth price. Initially I was going to purchase in morning before I left but ended up doing last night so I got at $2.99 price rather then the $0.99 a few hours later. I don't feel bad though.

In premium the voice is very pleasant and prompts come up in intervals that make it easy to follow without having to stare at screen.

I was a little shocked with app initially as the way it was worded implied more that the premium version just had the addition of voice, rather then several other features not in the core. Devs are prompt with reply and updated description and site to an extent so again can't complain.
 
just unbelievable for $.99 you can get a pretty sweet GPS!!

looks pretty sweet, I'm in Northern Michigan right now so i'm excited to see how it does with "less than stellar" ATT coverage.... POI seem to be in here where i'm at....

I also just picked up Mapquest $.99 "trial"... i'll also use that along with my previously purchased Gmaps east....

I guess i'm one that is still amazed with the iphone!!
 
I have both the Sport and Drive versions. They are awesome apps and are definitely better than the map program installed on the iPhone.
 
Tried to buy on iTunes shows .99 but will not allow purchase! says currently being modified. Anyone else???:apple:
 
Anything from this company is top quality. Its genius comes through owner, Phillipe Kahn who used the MotionX GPS to navigate in this year's TransPac race to Hawaii. It was the principle source of navigation and Kahn set an all time record in the process. His company, Fullpower, is incredible.

This app seems to kick butt on any of the other navigation ones for our phones. Its price is a steal.

My hope is that the window mount from Tom Tom will be compatible with Motion X.
