PICK YOUR PATH
Choose pitcher, position player, or two-way at sign-up, and the whole app adapts to you — your training, your metrics, your coaching.
FOR PITCHERS
• Log velocity and bullpens, import Rapsodo & TrackMan reports, and build your arsenal with movement plots.
• Biomechanical Movement Screening and a Mechanics Lab that breaks down your delivery frame by frame.
• Arm care, throwing programs, and workload tracking (acute-to-chronic) so you train the trend, not the ego.
FOR HITTERS
• A Spray Chart batted-ball lab, exit velo and bat speed tracking, and a Swing Lab that reads your sequencing and posture.
• Import hitting reports, log cage work, study a stance library, and find your MLB hitter comp.
MEET COACH CY
Your development coach, 24/7. It reads your profile, workload, and recovery and gives specific, personalized answers — hitting-specific for hitters, pitching-specific for pitchers.
READINESS & RECOVERY
A daily check-in plus your workload and sleep build a readiness score, so you know what your body is ready for today.
FOR COACHES & TEAMS
Run a roster, monitor each athlete's readiness and workload, and see a team health view — built for academies, travel orgs, and programs.

more Functionally, it’s the best pitching app I’ve used. Ability to track every aspect of my development from data, recovery, training, nutrition, you name it and it’s part of the program. Then to have AI functionality built in to assist with trends, tracking, recommendations, really make this app unreal. If you’re serious about development, every coach and player needs be using it.
Developer Response Appreciate you taking the time to write this — it means a lot. You nailed exactly what we set out to build: one place where your data, recovery, training, and nutrition actually talk to each other, so Coach Cy can surface the trends and tell you what to do next. That velocity-trend-against-workload-and-readiness picture is the insight a radar gun or a notebook just can't give you. Keep attacking your development — and pass it to a teammate. — The PlayersLab team

I purchased this app for my nephew about a month ago and he loves it! It monitors so much of his progress and has helped him with his pitching skills. It monitors his sleeping pattern and assists with his recovery. Well worth the money. Never thought an app could be created with so many features.
Developer Response Appreciate this so much — glad he's getting after it. The piece we're proudest of is exactly what you described: tying his sleep and recovery to his actual throwing workload so PlayersLab can flag when he's ready to push vs. when to back off. Tell him to keep stacking good days, and we're at support@playerslab.io anytime.

Has all the pitching tools you could need
Developer Response Appreciate the love, Boneal11 — fires us up to hear it this early. PitchLab.ai is built to be the full lab for serious arms: log every bullpen, watch your velo trend stack up against workload and readiness, and let Coach Cy break down your TrackMan and Rapsodo reports in plain English. We're shipping new tools constantly — keep grinding, and tell us what you want to see next. 💪

This update makes coaching feedback and assignments clearer for everyone.
FOR COACHES
• See the full catch-play log your athletes record — arm feel before and after, intent, energy, mechanics, and their notes — not just a throw count. (In a player's Folder and the team day feed.)
FOR PLAYERS
• Tap any assignment to read the full description.
• Completed assignments now stay in a new "Completed" section on Home — reopen one anytime, or Undo if you marked it done by mistake.
Plus stability and performance improvements.
1.0.47 3d ago
This update fixes a few coaching essentials and makes player planning visible to the team.
FOR COACHES
• Fixed: full-screen playback of the annotated video you send back to a player — it now plays, not just inline.
• Fixed: sending a file or clip to a player works reliably again (an upload-permission issue could silently block it).
• Fixed: your telestration comments and voice notes always confirm before the sheet closes — no more false "Sent."
FOR PLAYERS
• Plan a session (lift, bullpen, and more) and it now shows on your coach's calendar too, so they can see what you're doing.
Plus general stability and performance improvements.
1.0.45 Aug 6
Smoother, more personal PlayersLab.
NEW — MORE WAYS TO CONNECT
• Expanded wearable support in Recovery — connect your device and your sleep, recovery, and strain feed your readiness automatically.
RELIABILITY & POLISH
• Faster, more reliable sign-in and data sync across the app.
• A round of behind-the-scenes fixes and performance improvements.
Pain is always a stop sign — if anything hurts, rest and see a qualified professional.
1.0.44 Aug 5
A smarter, smoother PlayersLab — easier to learn, easier to coach.
NEW — GUIDED TOUR, REBUILT
• A hands-on walkthrough that actually drives the app: it scrolls to each feature, highlights it, and lets you try it at your own pace — with Back, Skip, and resume-where-you-left-off.
• Coaches get a setup checklist (add athletes, brand it, assign work, post a lineup, connect data) they can finish in any order.
COACHES
• Assign a program to multiple days at once — tap the days and it sticks on every one.
• Co-coaches can now schedule, assign, and post lineups (full staff access).
• Cleaner player folder: latest KPIs at a glance (no repeats), bodyweight folded in, schedule + assigned work in one place.
RELIABILITY
• Clearer error messages that say what's actually wrong — sign-in, permission, or billing — instead of 'check your connection.'
• Fixes for film sync, empty screens reading as missing features, and a crop of behind-the-scenes bugs.
Pain is always a stop sign — if anything hurts, rest and see a qualified professional.
1.0.43 Aug 3
A huge update for coaches and players.
FOR COACHES
• A rebuilt, simpler coaching experience: Team, Plan, Field, Cy, and Manage — everything in one obvious place.
• New Work Submitted view on the team calendar: see exactly what each player uploaded that day, player by player, and tap to open it.
• Catch play now shows in the player folder with a clean one-row-per-day summary.
• Faster, cleaner player folders — no more repeated readings.
FOR PLAYERS
• Your data syncs safely to the cloud and back — nothing lost on a new phone.
• More reliable sign-in and team joins.
UNDER THE HOOD
• Big security, privacy, and stability improvements across the app.
Pain is always a stop sign — if anything hurts, rest and see a qualified professional.
1.0.42 Aug 1
Sign in on a new phone and everything comes with you — your throwing and hitting history, film, mechanics reviews, and now your strike-zone and spray charts too. Every session backs up to your private cloud and restores on a new device, so you never lose your work.
COACHES ON ENTERPRISE: You can now choose exactly which features your players see. Turn off any tool — weightroom, nutrition, recovery, film, biomechanics and more — and it locks on your players' app with a "Disabled by coach" note.
NEW ON HOME: A Messages button always sits between Check-In and Schedule, with a red dot when your coach sends something new.
Plus fixes that make sending clips to your coach reliable, your scheduled workouts show on the Home calendar, and clearer messages when something needs your attention.
1.0.41 Jul 29
This one is about your data being where you expect it.
If you sign in on a new phone — or reinstall — PlayersLab now brings your account back with you.
• Your training history returns: sessions and velocity, daily check-ins and readiness, recovery, biomech reviews, KPIs, arm care, catch play, nutrition, workouts and bodyweight.
• Your film comes back too, with a progress indicator while it downloads instead of an empty screen.
• Your profile comes back, so the app no longer asks for your position and handedness as if you were brand new.
• Cage sessions now back up as well — swings, intent, contact quality and exit velo.
• Coaches: your saved custom exercises follow you to a new device.
FIXES
• Fixed a bug where signing in on a second device could overwrite your saved profile with a blank one.
• Coaches: the Team tab now points to where programs moved. They live on the Plan tab — nothing was ever deleted.
Restoring only ever adds what's missing. Anything already on your device is left exactly as it is.
1.0.40 Jul 28
The biggest update we've shipped — a rebuilt coaching experience, plus real fixes for athletes.
FOR ATHLETES
• Your training library now backs up to the cloud. Loadouts, scheduled workouts, custom exercises and arm-care routines come back on a new phone or after a reinstall.
• Film uploads are much smaller and faster. Clips are compressed before upload; the original stays untouched on your device and analysis still runs on the full-quality file.
• New Help & FAQ — 66 answers across 12 sections, searchable, in Profile.
• Workouts your coach assigns are now read-only, so the prescription can't be changed by accident. You can still log every set, rep and pound, and clear it when you're done.
• Apple Health workout export works properly now, instead of silently doing nothing.
FOR COACHES
• Five clear tabs: Team, Plan, Field, Cy and Manage. Everything you had is still there, just where you'd expect it.
• The athlete page is rebuilt around one action bar — Message, Assign, Film, Add data — with a readiness header that stays put as you scroll.
• One Assign flow (who, what, when) and one calendar, replacing the half-dozen doors that used to do the same job.
• One Film Studio with three modes: Watch, Mark up, Break down.
• Cy remembers your conversation between visits, and you can start a fresh chat any time.
• Rebuilt Team Report with a readiness scoreboard, and completion tracking that counts only work that's actually due.
• Save buttons moved to the top of builder screens, so you're not scrolling past a long list to save.
Thanks for the feedback that drove most of this. Keep it coming.
1.0.39 Jul 26
Coaches: a cleaner, faster team screen.
• Messaging moved front and center. Message your whole team at once, or tap any athlete to message them one-on-one — right from the team screen.
• The team screen is now built for coaches, not players. Assignments, roster, and messages each collapse, so a team opens as a clean index instead of a wall of text. Tap any section to expand it.
• Prescribed workouts now read in plain language. Assigned work shows the actual exercises, sets, and reps.
• One home for assigning work. Building and assigning multi-day throwing and lifting programs now lives in the Plan tab, next to the calendar.
• Fixed a layout bug that could make a player's profile render wider than the screen and cut off at the edges.
Thanks for the feedback — keep it coming.
1.0.38 Jul 25
Recovery is now built into the Routine Lab. Open “Routine & Recovery” in the Training tab and switch between your training routine and your recovery in one place.
Coaches: build throwing and lifting programs from a full exercise library, add your own custom exercises, and assign a program to athletes straight from any day on the calendar. You can also import TrackMan and Rapsodo reports for any athlete on your roster.
Plus a cleaner Training tab, a streamlined biomechanics capture flow, and a range of stability and polish fixes.
1.0.37 Jul 23
Coaches Mode just got a lot more powerful:
• NEW Team Calendar — plan your season on one schedule. Add practices, bullpens, lessons, lifts, and games for the whole team or specific players, and it lands on every athlete's calendar. Assign workouts, arm care, and notes right from a day, save player groups (like "Pitchers") to reuse, and see what's due at a glance.
• Coaches can now review each athlete's uploaded reports, arm care, nutrition, and workouts — and build multi-day throwing & lifting programs.
For players:
• A cleaner, simpler app — a streamlined Home and a lighter tab bar put your most-used tools one tap away.
• Your film now syncs across your devices — record on your phone, review on your iPad.
• See your assigned program day by day.
Plus performance and stability improvements, including a fix that keeps the app running cooler.
Also fixed: a sign-in issue that could keep some accounts — including Sign in with Apple — from connecting to the cloud, so Coaches Mode, teams, messaging, and film sync now connect reliably.
1.0.36 Jul 22
Biomechanics now reads more of your film.
• Tougher camera angles — including from behind or head-on — and busy facilities no longer get turned away. When a full 3D measurement isn't possible, you'll get a clearly labeled 2D estimate instead of being asked to refilm.
• Coaches: record a real film review. The clip plays while your voice and your on-screen drawings are captured together, and your athlete receives it as one video under "From your coach."
• Frame-by-frame stability and general quality improvements.
1.0.35 Jul 18
Introducing Routine Lab — build the training routine your own data supports.
• Routine Lab: PlayersLab now connects the habits you log — breakfast, prior-day lifts, sleep, hydration, mobility and recovery — to your real results, and shows which ones track with your best fastball velocity, exit velo and readiness. It turns your strongest patterns into a personal routine and flags what to keep re-testing.
• Hitters included: exit-velo and bat-speed drivers, not just pitching.
• A live coverage meter shows exactly what to log next to unlock each read, with clear EARLY / MODERATE / STRONG reliability labels.
• Smarter daily check-in: a new nutrition-quality input now feeds your readiness score.
• For coaches: see what's driving each athlete and "the day behind their PR" — the meals, lifts and sleep around a personal best — plus a team-wide drivers view for whole-roster patterns (Enterprise).
• Biomechanics Lab: smoother, more reliable frame-by-frame playback.
• Performance, stability and polish improvements throughout.
Every insight is a personal association from your own logs — shown with sample size and uncertainty, never as a medical or guaranteed outcome.
1.0.34 Jul 16
Biomechanics analysis is sharper in this update:
• Film from more angles — the Pitching Lab now reads deliveries shot from behind or head-on, not just side-on, and locks onto the correct release frame.
• More accurate readings — refined release / arm-slot timing, hip–shoulder separation, and stride & plant detection.
• Smoother frame-by-frame — scrub your analysis frame by frame without hitches, plus a crash fix.
Plus stability improvements throughout. Pain is always a stop sign — if anything hurts, rest and see a qualified professional.
1.0.33 Jul 14
This update makes the Biomechanic Labs more trustworthy and transparent:
• Unreadable or incomplete clips now ask for a retake—no invented measurements or coaching.
• Analysis stays locked to one athlete across the full clip.
• Movement Screen validates camera view and the actual support leg before scoring.
• Balance now tracks body sway relative to the planted foot.
• Trends compare only compatible measurement engines and complete test batteries.
• New optional High Accuracy mode adds confirmed height, standardized framing, and denser sampling.
Pitching Lab, Swing Lab, and Movement Screen analysis still runs on device.
1.0.32 Jul 12
The most accurate Biomechanic Lab yet — for pitchers and hitters.
• Sharper analysis: rebuilt stride-length and joint-angle math for truer pitching and swing readings.
• “This isn’t me”: tag who’s actually in a video — name, height, and bats/throws — so the breakdown and Coach Cy feedback are about the right athlete.
• Coaches can now film and analyze an athlete right from the roster: record or pick a clip, tag pitching or hitting, and send the review straight to the player.
• Refined hitting analysis for stride and base width.
• Reliability and performance improvements across workouts, messaging, and sync.
Questions or feedback? support@playerslab.io
1.0.31 Jul 10
More accurate biomechanics:
• Pitching & Swing Lab stride length and joint-angle readings are significantly more accurate, no matter how your video is framed.
• New "This isn't me" option — analyzing someone else's video? Tag who's in it and add their height for an exact stride measurement.
• Coaches can now record or upload a clip right from a player's folder, analyze it for them, and send it straight to their app.
Also in this update:
• Coach and player messaging with unread badges
• Workouts and progress now save more reliably
• Smoother account sign-up plus a range of fixes

1.0.30 Jul 9
THE BIOMECHANIC LAB, REBUILT
SMARTER SWING & PITCH ANALYSIS
• Detection now locks onto the moments that matter — foot plant, contact/release, and the barrel working through the zone — even on busy cage and bullpen clips.
• Every number is read at its own true instant: front knee and stride at the plant, spine tilt and arm/bat plane at contact or release, separation at peak.
• Swing analysis: highlighted the wrong leg? One tap swaps sides and re-traces the whole swing.
YOU CONTROL THE FRAMES
• Tap any measurement to see the exact frame it was measured on, skeleton overlay included.
• If a frame looks off, scrub frame-by-frame and set it yourself — the analysis re-runs around your pick. Works in both the Swing Lab and the Pitching Lab.

Plus accuracy and stability improvements across the app.

• Wrong leg highlighted? One tap swaps sides and re-traces the whole swing.

Plus accuracy and stability improvements across the app.
1.0.27 Jul 2
Field Conditions now matches where you're actually training.
• Local weather, wind, and arm-care guidance now use your device location instead of your network connection — so it shows your real field, not a nearby city or the wrong state.
• You'll see a one-time prompt to allow location while using the app. Your location is used only for local field conditions — it's never stored or shared.
• Steadier, faster readings that no longer drift between sessions.
Keep logging your work and checking your readiness before every outing.
1.0.25 Jun 30
