SatRadio
This app provides essential tools for radio and satellite communication engineers. It includes calculators and analysis features for antenna parameters, frequency calculations, link budgets, and modem performance. It also offers miscellaneous utilities for RF engineering tasks.
- Dish antenna analysis (axial ratio, gain, line of sight)
- Frequency calculations (phase noise, doppler, wavelength)
- Radio link analysis (coaxial losses, mismatch losses, EIRP)
- Modem performance metrics (C/N, C/I, PER, BER)
- Miscellaneous RF engineering utilities (dB calculator, converters)

Verdict
The clearest difference is rating: SatRadio at 5.0 against SatChannels's 3.8. SatRadio also leads on ads (none vs shown) and monetization model (free vs ad-supported). SatChannels's advantage is ratings volume (12 vs 1). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
SatRadio holds the better App Store score, 5.0 against 3.8. That said, the two scores are not equally well evidenced: SatChannels has 12 ratings behind it against 1, so its average is the more settled of the two.
SatChannels ships an update every 11 months, SatRadio every 10 months. The most recent releases landed on October 10, 2026 and October 5, 2026 respectively.
