Made for leagues. Built for coaches. Protects kids. Empowers parents.
Tired of planning drills and figuring out how to teach a 6-to-12-year-old to keep their feet shoulder-width apart? We built this so you can spend more time on the field and less on the clipboard.
One family. One kitchen table. One real problem.
This was built by a family who loves baseball and softball — and wanted a faster way to get from "I have practice in 90 minutes" to "I have a real plan." No more searching YouTube for drill ideas. No more legal-pad triage Sunday nights. Just open the app, pick the age group, pick what you want to work on, and go.
Kane PC — the MSP I run here in Bradenton — sponsors a handful of youth softball and baseball teams across Lakewood Ranch and the surrounding area, 6U through 10U plus a travel ball team. We do that because in a season where every parent is fighting screen time, youth sports is one of the few things that still gets kids outside, off the couch, and onto a field with their friends. That's worth investing in.
My wife Stef coaches. I'd love to coach myself, but I travel too much for work, so the deal in our house is: she coaches, I sponsor, and we both show up. She'd come home from practice with new ideas she wanted to try and no good way to plan them. Legal pads. Half-working GameChanger workarounds. Lineups drawn out on dinner napkins.
"You should just build the thing you wish existed."— Stef, after I showed her a working sample. March 2026.
So I did. Then we kept building it together. Stef shaped the practice planner from the coach's seat. Our three kids — all ballplayers themselves — contributed ideas we'd never have thought of from the kitchen-table side; the walkup songs and Game Mode dugout DJ are theirs, not mine. We figured out what parents actually needed by being parents on the same field. By April, both Miss Manatee Softball and Lakewood Ranch Little League were asking about deploying it across all their teams.
This is what happens when the people building the app are also the people in the lineup.

The app, from the dugout.
What you actually do on a Tuesday night — open the app, generate a plan, share it, run practice. No clipboards, no laptop, no printer.
90 seconds to a full plan.
Pick age group, pick a focus, hit generate. Done before you park.
Built for kids who all need to bat.
Full Roster Bats toggle. Hitting strength stars. Print-ready. Share by QR.
Rotation that actually validates.
Infield / outfield / bench balanced every inning. League rules baked in.
Walkup songs, jersey numbers, emoji.
The kids' idea, not ours. They love it. Parents love it more.
You signed up to coach. Not to project-manage.
Four audiences. One app. Each one taken seriously.

Where Diamond Coach really separates. Send parents a 20-minute at-home practice plan, generated from what their kid actually struggled with at practice. Backyard, driveway, park — no equipment beyond a glove and a tennis ball.

- COPPA-aware data flows
- Parent-controlled visibility
- Deletion requests honored
- Stat history travels with the kid
- Audit trail you can inspect
For leagues
What other apps treat as an afterthought. Diamond Coach is built to deploy at the league level — one commissioner, every team, one set of compliance rules across the org.
- Pre-populated leagues for your area
- Cross-team rotation tracking
- League-wide compliance rules
- Commissioner dashboard
- White-label option
Scan, don't import.
Most parents have never opened a CSV file in their life. Most volunteer coaches haven't either. Diamond Coach lets coaches and parents hand off lineups, rosters, and at-home practice plans by scanning a QR code with their phone.
No email attachments. No exports to download folders. No "wait, is that the right file?" texts at 5:25 PM on a Tuesday.
Yes, GameChanger CSV and PDF still import — for the leagues that already have years of data. But for new teams, just scan.
Honest pricing. No seat fees. No ads. Cancel anytime.
