The Gamechanger app tracks over 150+ statistics for baseball and softball hitters, pitchers and fielders. These stats are automatically updated as you score the play by play of your games. So even if you don't know what the abbreviations mean or how they were calculated, you'll have access to them all!
Some of the abbreviations are simple and common like "PA" (plate appearance) or "H" (hits). Others are more complex and less common but can be highly insightful, like "6+" (at bats with 6 plus pitches) and "HHB" (hard hit balls).
Here are all of the stats with their abbreviations and explanations.

Notes on Batting Stats
#1 ABs and PAs are not the same. At bats are not the same as plate appearances. Plate appearance count each time the batter was at the plate but not all plate appearances count as at bats. Walks, hit by pitches, sacrifices and catchers interference do not count as at bats but they are counted as plate appearances.
#2 Errors negate hits or extra bases. If a player hits the ball and ends up on base but you credited the centerfielder with an error, it will not appear as a hit. If the player records a single but then the outfielder makes an errant through that results in the runner advancing to second base, it will be scored as a single. This is assuming that you score it properly in Gamechanger.
#3 Keeping detailed pitch by pitch and play by play records leads to more accurate stats. For instance, resist the urge to not log foul balls with 2 strikes. Although it seems meaningless, seeing how many pitches each batter sees per plate appearance can be a useful statistic for players and coaches.

Notes on Pitching Stats
*#1 Velocity and pitch type must be turned on and only tracked and visible when a camera is live streaming the game. Most teams don't have pitch tracking on as it requires a radar gun and live stream set up. If you have it added, it will appear in your advanced stats area.
#2 Game averages like ERA are based on the game length of the league (which is often less than the MLB standard of 9 innings). Here's an example, if a player gives up 1 earned run over 9 innings, their ERA is not necessarily going to be 1.00 like it might seem based on our typical understanding of ERA. The ERA is average per regulation game length, so it will actually be lower than 1.00 if the regulation game length is shorter than 9 innings. For instance, if the regulation game length is 7 innings, giving up 1 run over 9 Innings pitched in a season would give an ERA that is actually 0.77. This holds true for stats like K/G (strikeouts per game)
#3 "Hard" and "Weakly" hit balls depend on type scored. Hard hit balls are logged as "line drives" or "hard ground balls" whereas weakly hit balls are logged as "ground balls" or "fly balls."
Gamechanger Fielding Stats
E: Errors
A: Assists
PO: Putouts
TC: Total chances
DP: Double plays
TP: Triple plays
FPCT: Fielding percentage
Notes on Catching Stats
#1 Assists vs. Putouts. Although they sound the same, they are different . An assist is credited to the person who aids in getting a batter out but is not the one to tag them or the base or catch a ball in the air. A putout is credited to the last player who touches the ball before an out is made. On a ground ball hit to the SS and thrown to the 1B for a force out at first, the SS gets the assist and the 1B gets the putout. Catchers and 1st basemen get the bulk of putouts in baseball (catchers get all strikeouts as putouts).

PB: Passed balls allowed
SB: Stolen bases allowed
SB-ATT: Stolen bases allowed - Stealing attempts
CS: Runners caught stealing

Notes on Catching Stats
#1 Passed balls vs. wild pitches. A passed ball is a pitch that a catcher reasonably should have stopped. A ball that hits in the dirt in front of them but gets between their legs, for instance, is typically considered a passed ball. A wild pitch, on the other hand, is a pitch that is so errant that it would be unreasonable or impossible for the catcher to receive or block it. Balls must result in a baserunner advancing for them to be logged as either a passed ball or wild pitch.
