I tried the Hey Blu app in the batting cage and pitching sessions using both baseballs and softball and also used the app during my softball games. Found the setup is very easy to do following the on screen prompts and the app works great calling balls and strikes and keeping track of the number of pitches and pitch location. Very cool app and highly recommend it for coaches, players and parents! -- RMKCB5, 2026-07-21 ### ***** "Very cool app" Just used it with my two sons. Once we set it up, it worked perfectly. After the session, each had the hard data of exactly where each pitch crossed the plate. We used it with a Bluetooth speaker and it was really fun to hear the loud STRIKE! calls. Will definitely be telling my other baseball dads about this. -- BIMBIMBIM26, 2026-07-21 [View all HeyBLU reviews and detailed analytics on AppTail](https://app.apptail.io/signup?utm_campaign=ai-crawl&utm_content=reviews) ## HeyBLU In-App Purchases | Item | Price | |------|-------| | Pro Monthly | $4.99 | | Pro Annual | $49.99 | ## Apps Similar to HeyBLU - [Casmium Velo Tracker](https://apptail.io/app/casmium-velo-tracker-ksjw/united-states) - [The Baseball Lab](https://apptail.io/app/the-baseball-lab-gobx/united-states) - [Pine Mountain Lake Golf Course](https://apptail.io/app/pine-mountain-lake-golf-course-Gbby/united-states) - [ScoutEdge: Baseball Analytics](https://apptail.io/app/scoutedge-baseball-analytics-Upxy/united-states) - [Who's on Second: Lineup Maker](https://apptail.io/app/whos-on-second-lineup-maker-NFqz/united-states) - [Baseball Tracker: Radar Gun](https://apptail.io/app/baseball-tracker-radar-gun-DXsz/united-states) - [HitLab - AI Swing Coach](https://apptail.io/app/hitlab-ai-swing-coach-teVz/united-states) - [DialedIn Pitch Calculator](https://apptail.io/app/dialedin-pitch-calculator-eSsA/united-states) - [PlayersLab: Hitting & Pitching](https://apptail.io/app/playerslab-hitting-pitching-twWA/united-states) ## HeyBLU Available In - [United States](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/united-states) - [Argentina](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/argentina) - [Australia](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/australia) - [Barbados](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/barbados) - [Canada](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/canada) - [Chile](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/chile) - [China](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/china) - [Germany](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/germany) - [Dominican Republic](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/dominican-republic) - [Spain](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/spain) - [France](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/france) - [Grenada](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/grenada) - [Italy](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/italy) - [Jamaica](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/jamaica) - [Japan](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/japan) - [United Arab Emirates](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/united-arab-emirates) - [Cayman Islands](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/cayman-islands) - [North Macedonia](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/north-macedonia) - [Mexico](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/mexico) - [Malaysia](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/malaysia) - [Namibia](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/namibia) - [Norway](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/norway) - [Philippines](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/philippines) - [Qatar](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/qatar) - [Romania](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/romania) - [Sweden](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/sweden) - [Thailand](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/thailand) - [Türkiye](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/turkey) - [Taiwan](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/taiwan) - [Ukraine](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/ukraine) - [Kenya](https://apptail.io/app/heyblu-baseball-strike-zone-pwWA/kenya) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
