Storm!

Storm! is a compact utility that measures how far a lightning storm is by timing the interval between a flash and its thunderclap, helping you decide whether to seek shelter. With a simple two-button workflow—tap Lightning when you see the flash and Thunder when you hear it—Storm! converts the time gap into an approximate distance in meters so you can judge risk quickly. The app is aimed at outdoor enthusiasts and anyone who wants a quick safety check during thunderstorms, and it also serves as a hands-on way to learn about sound propagation and basic storm physics.

Key Features

⭐ Two-button timing: tap Lightning at the flash and Thunder at the clap to record precise moments.

⭐ Instant distance calculation in meters based on the time difference between light and sound.

⭐ Clear, minimalist interface that’s easy to use even for first-time users.

⭐ Educational tool explaining sound propagation and the physics behind thunder and lightning.

⭐ Developers plan to add miles as a unit option in a future update.

⭐ Simple operation designed to give fast, actionable information—Storm! focuses on clarity and speed.

Advantages

✅ Provides a quick, on-the-spot estimate to help you decide when to seek shelter.

✅ Manual two-button workflow minimizes setup so you can measure distance immediately.

✅ Teaches basic meteorological concepts through direct, hands-on measurement.

✅ Language localization and GPS integration are planned, so Storm! may become more widely accessible and precise.

Disadvantages

❎ Current output is in meters only; miles support is not yet available.

❎ Accuracy depends on user reaction time when tapping the buttons, so readings are approximate.

❎ App provides an estimate rather than a precise measurement; it should be used as a safety guide, not a scientific instrument.
