# SatRadar vs Satellite Tracker 3D

The clearest difference is ratings volume: Satellite Tracker 3D at 69 against SatRadar's 5. SatRadar's advantage is update cadence (every 2 days vs every 4 days). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. SatRadar sells 2 one-off in-app purchases and Satellite Tracker 3D sells 4 in-app purchases, starting at $2.99 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 — 4.8 for SatRadar against 4.7 for Satellite Tracker 3D. That said, the two scores are not equally well evidenced: Satellite Tracker 3D has 69 ratings behind it against 5, so its average is the more settled of the two.

SatRadar ships an update every 2 days, Satellite Tracker 3D every 4 days. The most recent releases landed on October 24, 2026 and October 25, 2026 respectively.
