RAY is the ultimate running app, which lets you improve your speed on every single run with real-time comparisons!

No more waiting to complete a run to know if you beat your previous time! RAY will tell you if you are running ahead or behind, and by how much, while you are running!

Besides showing the current distance, time, speed and calories, and tracking your path on the map, RAY also tells you how many feet or miles your are running ahead or behind compared to your previous run.

You can also see detailed information about your current run and your previous run, expanding our second by second detailed charts.

If you are ahead compared to your last run, RAY will also display your "ghost" on the map, so you can see how far behind you were last time at this point in the run!

Running different paths each time? We've got you covered! We will compare your current run with your previous run even if you run in different locations!
RAY will even display your "ghost" on your current path in the map, to show you where you would have been last time if you run the same route.

If you are running longer than the previous time, or it's your first run using RAY, we will also estimate your pace so you can compete against it and improve even on your first run or those extra miles you are running!

No matter if you are training for a marathon, doing speed training, trying to get in shape or lose weight, RAY will allow you to track your progress while you are running, so you can improve on every single run.
