StratManager puts the math behind your Strat-O-Matic cards to work before the first pitch. MATCHUP CALCULATOR — FRONT AND CENTER Pick any batter. Pick any pitcher. Set the ballpark. StratManager instantly shows you the on-base probability and home run percentage for that matchup straight from the card data — so you know before you commit to a lineup who actually has the edge. Adjust for ballpark conditions using the same left/right single and home run ratings from your Strat-O-Matic park card — and watch the probabilities shift in real time based on whether your batter hits lefty or righty. LINEUP INTELLIGENCE Stop guessing which order puts the most runners on base. With your Strat-O-Matic card data imported, every lineup decision is backed by real probabilities. Stack your best OBP against a weak pitcher. Protect your power hitter. Use the data the way a real front office would. POWER RANKINGS See projected league standings ranked by team batting and pitching strength. Know how your roster stacks up before the game is played. FULL SEASON TRACKING Every game you play feeds real stats into season leaderboards — ERA, batting average, OPS, strikeouts, saves. Watch how your cards actually perform over a full season and spot which players are beating — or missing — their expected numbers. COMPLETE SCOREKEEPING WHEN YOU NEED IT Play-by-play scoring, live box score, earned run tracking, double plays, triple plays, and passed balls — all handled with MLB-accurate rules. The scoring feeds season stats so you can see exactly how your cards performed over a full season. FREE TO PLAY Both built-in sample teams are fully playable with every feature enabled — including the matchup calculator and power rankings. Try the full experience before buying.

Verdict
The clearest difference is ads: StratManager at none against 20's shown. StratManager also leads on rating (5.0 vs 4.8). 20's advantage is ratings volume (4.6K vs 1) and chart position (#19 vs unranked). On price, in-app purchases, monetization model and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. StratManager sells 1 one-off in-app purchase and 20 sells 7 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
StratManager holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: 20 has 4.6K ratings behind it against 1, so its average is the more settled of the two.
