«Magnetology» is an application which permits one to watch the forecast of geomagnetic storms and the state of Earth´s geomagnetic field. WHY IS IT SO IMPORTANT? Geomagnetic storms adversely affect the health of humans. They can cause aches, dizziness, rapid heart rate, and abnormal blood pressure. People with abnormal conditions of the blood and of the cardiovascular and autonomic nervous systems are particularly susceptible to the influence of geomagnetic storms. The degree of magnetic storms’ influence on a particular person depends on many factors, including health status, stress, physical and emotional fatigue, natural predisposition. Not only can geomagnetic storms have a negative impact on humans, but also on communications, navigation, and power. By taking into account the forecast of geomagnetic storms, you can plan difficult decisions, avoid high physical stress, and protect yourself from negative consequences. Our application will help you with this. ABOUT THE NATURE OF THE GEOMAGNETIC STORMS The Earth's geomagnetic field changes occur under the influence of the Sun. The intensity of the impact is not constant and depends on the ongoing processes on the solar surface. The strength of geomatic field disturbances is characterized by the value of Kp index. The Kp index can be assigned values from 0 to 9, where 0 is the absence of disturbances and 9 represents extremely strong perturbations of the earth´s geomagnetic field. Disturbances with a Kp index of 5 and above are called storms. The number of geomagnetic storms per year can reach 50!

Verdict
The clearest difference is ratings volume: Nautide at 3.4K against Magnetology's 82. Nautide also leads on chart position (#59 vs unranked) and iOS requirement (12.0 vs 15.6). Magnetology's advantage is review sentiment (80% vs 67%). On price, rating, update cadence and ads 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. Magnetology sells 1 one-off in-app purchase and Nautide sells 2 in-app purchases, starting at $6.99 per month. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.6 for Magnetology against 4.8 for Nautide. That said, the two scores are not equally well evidenced: Nautide has 3.4K ratings behind it against 82, so its average is the more settled of the two. Written reviews are what separate them: 80% of Magnetology's written reviews are positive against 67% of Nautide's.
Both ship on a similar rhythm, roughly every 3 months. The most recent releases landed on November 1, 2026 and November 11, 2026 respectively.
