Attenuator vs ScanYourWorld
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

This mobile app lets you scan your world with LIDAR and builds a model of your real world around you. Create your own 3D model in the iPhone. Without any connection to a cloud service. Beste data security and privacy. All data and process are on your iPhone. After building the model in near real time make notes, measure lines and areas and export it to the place you want to. Share the model with or without notes and drawings. You are in the command seat. Please note the app is live in a first version and we are very keen on your feedback, comments and experiences with the app. By the way - in PRO mode you can even experience a completely new interaction possibility with your real world.

Verdict
The clearest difference is update cadence: ScanYourWorld at every 2 weeks against Attenuator's every 7 months. ScanYourWorld also leads on device support (3 vs 1) and iOS requirement (14.5 vs 17.6). On price, ads and in-app purchases there is nothing between them.
