StormTap

StormTap helps you estimate how far away lightning is by pairing the flash you see with the thunder you hear. During a storm, tap LIGHTNING when you see a flash, then THUNDER when you hear it. StormTap estimates the distance from the sound delay and displays the result on a clear map with your recent strikes. StormTap Pro unlocks advanced tools on this device: complete history, timeline navigation, advanced maps, sensor calibration and assisted automatic capture. Collaborative features such as network triangulation and speed ranking are planned to activate progressively depending on rollout and available observations. StormTap is designed for local storm observation. Distances are estimates and must not be used as a safety system. Always follow official weather alerts and local safety instructions.

Verdict
The clearest difference is ads: StormTap at none against StormCast's shown. StormTap also leads on update cadence (daily vs weekly). On price, in-app purchases, device support and iOS requirement there is nothing between them.
