Ekzellenttttt!!!

Cheapest magnetometer you’ll ever find!! If your a ham radio enthusiast you can use it to measure the earths magnetic field strength. an important component in frequency propagation, and also space weather like CME’s that affect it. It also shows a real kick in the magnetic fields with approaching thunderstorms. Lightning actually starts from the ground up. I was measuring in a bad storm in the mountains once and the readings went so high that the phone got so hot it burned my hand!!! Wicked citizen science opportunities! Cheers David Wilde

I will never be the same

This app has changed me forever, before I was simply the living dead. Now, I am awakened

This works

Thanks for a great app

It works

👍🏾

Not a fake

App actually worked. Was significantly impressed.

FAQ

What does Tesla Bot do?

Tesla Bot functions as a Geiger counter for magnetic fields. It uses your device's built-in magnetometer to measure magnetic field strength and produces synthesized Geiger counter-style clicks that vary with the field's intensity.

Does Tesla Bot detect radioactivity?

No, Tesla Bot does not detect electromagnetic radiation like radio waves, nor does it detect ionizing radiation or particles, which is commonly referred to as radioactivity. It primarily detects magnets and ferromagnetic materials.

What magnetic field range can Tesla Bot detect?

The approximate range in microtesla (µT) that your device's magnetometer can sense is between 30 and 2000 µT. This allows for detection of a variety of magnetic field strengths.

What operating modes does Tesla Bot offer?

Tesla Bot provides several operating modes. These include detecting changes in magnetic vector (delta µT), showing compass degrees with distinct clicks at north, and allowing selection of individual vector axes for focused measurement.

Does Tesla Bot work on all devices?

Tesla Bot requires a device with a compass (magnetometer) to function. Current iPod Touch models do not have this sensor and therefore will not work with Tesla Bot. It is supported on iPhone and iPad.

Is Tesla Bot free to use?

Yes, Tesla Bot is available for free. There are no costs associated with downloading or using its features, and it does not offer in-app purchases.

How often is Tesla Bot updated?

Tesla Bot was last updated on October 1, 2015, with version 1.1. While it has not received recent updates, its core functionality remains stable for devices that support its requirements.

Does Tesla Bot have ads?

No, Tesla Bot does not contain advertisements. As a free utility app, it provides an ad-free experience for users.
