The receiving iPad does not need a second subscription. YOUR ORIGINAL RADAR GUN RAiDAR's original pitch-velocity mode remains included. Record a pitch with your iPhone to get estimated velocity from on-device ball tracking. Organize your sessions, replay your throws, and export videos with a velocity overlay. ONE SUBSCRIPTION, BOTH MODES Monthly and Annual subscriptions include Flightcast and Radar Gun. Existing active RAiDAR subscribers receive Flightcast as part of their current access. Any available introductory offer, eligibility, localized price, duration, and renewal terms appear before purchase. Subscriptions renew automatically unless canceled through your Apple subscription settings. BUILT FOR REAL PRACTICE Follow the in-app setup guides and use suitable swing clearance, an impact-rated net or screen, and appropriate protective equipment. Velocity and launch-angle readings are estimates. Flightcast ball flight and distance are simulations. Results depend on lighting, camera placement, stability, device capability, and a clear view of the ball. ON-DEVICE ANALYSIS Pitch videos and hitting analysis are processed on your device. Nearby Display sends session and replay data directly to your paired iPad. Flightcast uses microphone transients to help time contact and does not retain an audio recording.

Verdict
The clearest difference is rating: b4 at 4.2 against RAiDAR's 3.3. b4 also leads on monetization model (freemium vs subscription) and ratings volume (152 vs 7). RAiDAR's advantage is review sentiment (100% vs 81%) and update cadence (weekly vs every 3 weeks). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. b4 sells 4 in-app purchases, starting at $3.99 per month and RAiDAR sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
b4 holds the better App Store score, 4.2 against 3.3. That said, the two scores are not equally well evidenced: b4 has 152 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 81% of b4's written reviews are positive against 100% of RAiDAR's, so the app with the better star average is not the one people write more warmly about.
b4 ships an update every 3 weeks, RAiDAR weekly. The most recent releases landed on November 3, 2026 and October 31, 2026 respectively.
