Attenuator vs RF Power Calculator
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Attenuator
Calculate output voltage, power, and attenuation based on input values and dB of attenuation. Features NMR-specific calculations for pulses and measures local magnetic fields and barometric pressure.
- Calculate output voltage and power
- Specify input voltage (Vpp or Vrms)
- Calculate attenuation in dB
- NMR pulse calculations
- Measure local magnetic field
- Display barometric pressure

Attenuator is a utility for anyone working with radio frequency sources and needs to know power and voltage after attenuation. You can specify an input voltage (Vpp or Vrms) and dB of attenuation to get the output voltage, power and attenuation. The impedance can be specified, typically 50Ω for most systems. There is a new emphasis on NMR utility, with options for calculating pulses based on reference power and pulse length. Powers are in Watts, dBm, and dB values. Measure local magnetic field to check stray static fields from magnets. See the local barometric pressure, useful if the magnet boil-off is high

Verdict
The clearest difference is in-app purchases: RF Power Calculator at none against Attenuator's 1. RF Power Calculator also leads on device support (3 vs 1) and iOS requirement (9.0 vs 17.6). Attenuator's advantage is ratings volume (8 vs 1). On price, rating 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. Attenuator sells 1 one-off in-app purchase. RF Power Calculator asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 5.0 for Attenuator against 5.0 for RF Power Calculator. That said, the two scores are not equally well evidenced: Attenuator has 8 ratings behind it against 1, so its average is the more settled of the two.
