My Favorite Batting App!

Hands down my favorite batting app! The clutch mode is an absolute game-changer—perfect for simulating pressure situations. I love how responsive and realistic it feels. This app is a must-have. Highly recọmmend for players looking to level up their game!

Accurate EV Insights for Batting Practice

I love how this app gives accurate Exit Velocity data right away. It's easy to use and adds real depth to my training. It makes it easy to identify weaknesses and track progress.

Game-Changing Training Tool!

Fantastic! It accurately tracks EV readings and helps me analyze my swing like never before. It feels like having a real coach in my pocket!

Fun and Easy AI Batting Practice

Great for kids! It's simple to use and fun. Very engaging for young players. Highly recọmmended!

Great app

This app works really well, but every few times I swing it just gives me no reading even though it gave me readings before, also I would love to see how far I hit the ball in feet. Overall good app but could use some changes.

Response from developer

Hi Danny1846, thanks so much for your feedback! Regarding the occasional swings with no reading, feel free to DM us on Instagram (@b4.app) or email us at support@b4-app.com. We’d be happy to help. Also, great idea on showing distance! That’s already on our roadmap, and we’re excited to bring it to a future update so you can see how far your hits travel.

Great tool for biomechanics!

I began to use this app for my son and for some players I regularly train in private lessons (8-10yrs). At their age they may understand the concepts of how their body should move for an efficient swing, but they also may not be able to feel or tell the difference when they hit the ball with a bad swing or a good swing. They may just think “I hit it hard” even though they casted their hands out and came around the ball for example. So this tool is great as it gives real time feedback and showcases the difference between a “bad habit” swing vs a good swing we are training on. As a coach, I recommend.

Really I had to pay you could have gotten 5 stars but I had to pay so you get a 1 star

Great tool!

Trying out this app I saw Coach Murph used in one of his videos. This is an excellent tool for coaches and players for a great visual for swing analysis. I like to utilize video to break down a swing and this app takes it to the next level with the great features including exit velocity, launch angle, and bat path tracing. Love this. I only needed things I already had around the house. A phone and a tripod. Love b4!

Try free sample first

Nice user interface. Not accurate. Velo metrics are off by roughly +\- 15%

Swing Progress Tracker

Been using it for 3 months and love cọmparing early swings to recent ones. Helps my kid stay motivated and focused.

Good for All Ages

Using this with both my 10U team and my 15-year-old daughter. The app adjusts well to different skill levels and still gives meaningful insights.

Solid App With Real Potential

Not perfect yet but already very useful. Looking forward to future updates. Would love to see more in-depth analytics.

Very Accurate Readings

Exit velo readings match what we see with HitTrax. Great for at-home training when we’re not at the facility.

Great for Parents Who Want to Help

I’m not a coach, just a dad trying to support my kid. This app made it easy to spot what he was doing wrong and helped us fix it together.

Terrible

Just stopped working wasted my money trash

It doesn’t do anything

I might be doing smth wrong but I tried it for 30 minutes and it didn’t try to do anything there was no reads

Login in problem

I cannot sign up when I download the app it keeps saying failed logging and no matter if I delete the app and redownload the app, restart my phone, or anything it won’t allow me to login

Inaccurate measurements

It is only sometimes accurate and it takes forever to set up. It is hit or miss. When it works it works very well

Response from developer

Thanks for the feedback, CadenLee20! Accuracy can be affected by lighting, setup, and other factors. We’re constantly working to make it easier to use. Feel free to reach out at contact@b4-app.com or DM us @b4.app. We're happy to help!

Won’t work

I set it up properly it still won’t work I don’t understand.

Great
