Stop running your lineup on a napkin or a spreadsheet. Fieldwork is the coaching app for youth and travel baseball. Build your batting order, set your fielding inning by inning, track pitch counts and rest days, and keep playing time fair, all before first pitch. Built by a coach who got tired of spreadsheets and group texts. SMART BATTING ORDERS Get a suggested batting order in one tap, with the reasoning behind it. Adjust for matchups, then lock it in. You call it, Fieldwork does the math. FIELDING, INNING BY INNING Set every position for every inning on one screen. Built-in warnings catch it before a kid gets stuck on the bench two innings straight, so playing time stays fair. PITCH COUNT AND REST DAYS Track pitches by player and get flagged before anyone crosses a limit. Rest days follow each player's league age, so you stay legal without doing the math in your head. GAME DAY, FROM YOUR POCKET Run the game from your phone. See who's playing where each inning, track the bench, and make changes on the fly. TURN YOUR STATS INTO DECISIONS Import your GameChanger stats and Fieldwork turns them into pitching workload, rest-day availability, and player insights that shape your lineup. COACH TOGETHER Invite your assistants so your whole staff sees the same lineup, fielding, and pitch counts, synced during the game. EASY SETUP Snap a photo of your roster and Fieldwork pulls in the names and numbers. Setup takes minutes, not an evening. Fieldwork is for coaches who take the job seriously. Travel, rec, Little League, or middle school, if you manage a roster and a pitching staff, this is your dugout command center. Questions or feedback? We're a small team and we answer.

Verdict
The clearest difference is ads: Fieldwork at none against Mustard's shown. Fieldwork also leads on rating (5.0 vs 4.7) and update cadence (weekly vs every 5 weeks). Mustard's advantage is ratings volume (213 vs 4). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Mustard sells 15 in-app purchases, starting at $7.99 per month and Fieldwork sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
Fieldwork holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Mustard has 213 ratings behind it against 4, so its average is the more settled of the two. Written reviews point the same way: 83% of Mustard's written reviews are positive against 100% of Fieldwork's.
Mustard ships an update every 5 weeks, Fieldwork weekly. The most recent releases landed on October 27, 2026 and October 6, 2026 respectively.
