  • Solar activity tracking
  • Kp and A Index data
  • Solar wind speed
  • Solar flare detection
  • Proton and electron flux
  • Aurora prediction
Read full description

The Magnetic Storms application was originally developed to allow monitoring of the Earth's magnetic field in near real time, using data from GOES satellites that constantly monitor solar activity and a set of magnetic stations distributed around the Earth. With the improvement of the application due to the huge number of users and the availability of new parameters related to the Sun and Space Weather by the space agencies, lots of other information was added and they are shown in a simple and intuitive way. The main parameters presented are the Kp Index, the A Index, the instantaneous speed of the solar wind, the number of class C, M and X solar flares observed in X-rays, in addition to the flux of protons and electrons, flux of X-rays and magnetic field measurements observed by GOES-16. With an analysis of this information it is possible to anticipate sudden changes in the Earth's magnetic field at ground level and the occurrence of aurora with some advance. An ideal application for anyone who wants to monitor solar activity and its implications on Earth, such as problems in the transmission of radio and TV waves, blackouts in electricity transformer stations, auroras, magnetic storms. It is the perfect app for anyone interested in Space Weather in general, and is available in English, Portuguese, Spanish, Italian and French. As a way of keeping the app distributed for free and constantly updated, we kindly ask you to rate the app ("stars") and write a brief description of why you use it and (we hope you) enjoy it. Criticism and suggestions are always welcome at mikebm10.appledeveloper@gmail.com. NOTE: the parameters shown in the application are obtained from the research entities responsible for their collection and processing, and depend on the availability and access to the electronic servers of these entities. Any connection speed problems with the servers or temporary unavailability of information by those institutions can affect the functioning of the application, and are beyond the control of the developers. Problems should be reported by email mikebm10.appledeveloper@gmail.com, with a description of the observed effects. Please do not assign a low rating in the evaluation of the application for possible failures in the servers, which are not our responsibility. An email message will be promptly answered and possible measures will be taken. We thank you for your understanding.

Physics Lab is all-in-one Sensor app which let you know physical entities around you like acceleration, magnetic fields, light intensity, sound decibel and much more... Physics Lab measures physical parameters by using your device sensors which typical device contain bunch of those sensors! Application give output in high precision with short intervals based on your sensor's capabilities. In Physics Lab, you can observe physical data in coordinates (X-axis, Y-axis, Z-axis) or in scalar magnitude. If you want, you can export sensor data into Excel by one click! Using export to excel feature you can obtain statistical information about your measurement. Physical quantities that can be measured Physics Lab: * Accelerometer: Measuring acceleration around your device. Output in m/s2 for x, y and z axes. Also, you can eliminate gravity from your measurements by one click and see real acceleration. * Magnetometer: Measuring magnetic field around your device. Output in µT for x, y and z axes. * Gyroscope: Measure angular inclination in x, y and z axes. Output in degree (°) * Luxmeter: COMING SOON * Barometer: Measure atmospheric pressure. Output in bar. * Noisemeter: Measure loudness around you. Output in dB. If you like our application, you can give us 5 stars. You can forward any suggestions, requests or concerns to info@grandmount.org

Verdict

The call

The clearest difference is update cadence: Physics Labs at every 2 weeks against Magnetic Storms's every 12 months. Physics Labs also leads on review sentiment (100% vs 82%) and monetization model (ad-supported vs free with in-app purchases). Magnetic Storms's advantage is iOS requirement (12.4 vs 15.6). On price, ads, in-app purchases and device support there is nothing between them.
