Track the planetary K-index (Kp) — the standard measure of global geomagnetic activity. Planetary K-Index shows live Kp from NOAA, official charts from GFZ Helmholtz Centre for Geosciences, and related space-weather products so you can see quiet conditions, active periods, and geomagnetic storms at a glance. WHAT YOU GET • Kp — estimated planetary K-index with scrubbable bars, conditions, and a 24-hour forecast • NOAA — station K & A indices, Boulder magnetometer, geospace, ACE, and aurora maps • Europe · GFZ — official Kp nowcast charts, Hp30, daily plots, Bartels diagram, plus Poland INTERMAGNET magnetograms (Belsk & Hel) • Pull to refresh on live data and chart screens WHY Kp MATTERS The K-index (and planetary Kp) characterizes disturbances in Earth’s magnetic field. Space weather agencies use it for geomagnetic alerts and warnings. Higher Kp values mean stronger activity — and better chances of aurora at lower latitudes during storms. FROM THE MAKERS OF QUICK SCHUMANN CHECK A focused companion for people who follow Kp, geomagnetic storms, and space weather — without the clutter.

Verdict
The clearest difference is rating: Planetary at 5.0 against Yin·Yang's 3.7. Planetary also leads on price ($0.99 vs $1.99). Yin·Yang's advantage is update cadence (every 2 months vs every 18 months) and review sentiment (67% vs 40%). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.

Planetary costs $0.99 and Yin·Yang $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Planetary holds the better App Store score, 5.0 against 3.7. Both are backed by a comparable volume of ratings — 4 and 3 respectively. Written reviews complicate that: 40% of Planetary's written reviews are positive against 67% of Yin·Yang's, so the app with the better star average is not the one people write more warmly about.
Planetary ships an update every 18 months, Yin·Yang every 2 months. The most recent releases landed on October 29, 2026 and October 30, 2026 respectively.
