EBColson:
I new to the app. What's a "meter" and how is it used. I see it on all the balls I looked to purchase.
Welcome aboard.
The "meter" is the section showing how much power you are using when the club head is pulled back to hit the ball. When you release, the line on the meter moves right and you try to click/tap etc., when the line aligns with the desired hit point. Hitting this line (dinging the meter) results in the best hit for distance and direction. Missing either side sends the ball in that direction, usually with less distance.
The meter number you see on the ball attributes reflects relatively how fast the meter moves when using that ball. The higher numbers (up to 5) mean the meter moves slower; lower numbers mean it moves faster. Slower is better for timing, but the balls cost more - sometimes a lot more!
I suggest you click the link for How to Hit the Ball in the FAQ section.
