Attenuator vs BLE
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
BLE
This utility tool assists developers in creating and maintaining Bluetooth Low Energy products. It enables connection establishment, monitoring, and configuration for RF testing of BLE devices. Log files can be shared for further analysis.
- Connect to BLE devices
- Monitor connections
- Configure connection parameters
- Start/stop test mode
- Share log files

This tool is intended to support developers in their work to develop and maintain Bluetooth Low Energy products. BleRf Test can measure the quality of an RF link in both direction for any product implementing the BLE service for RF test. Features: - establish a connection to a BLE device - monitor said connection - share log files with other smartphone apps This app is only intended to support the development of BLE devices.

Verdict
The clearest difference is rating: Attenuator at 5.0 against BLE's 3.0. Attenuator also leads on update cadence (every 7 months vs every 64 months) and ratings volume (8 vs 1). BLE's advantage is in-app purchases (none vs 1) and device support (3 vs 1). On price 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. BLE asks for nothing beyond the download.
Attenuator holds the better App Store score, 5.0 against 3.0. 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.
Attenuator ships an update every 7 months, BLE every 64 months. The most recent releases landed on September 14, 2026 and September 17, 2026 respectively.
