Estimated revenue

A model estimate with a likely range, not a reported figure.

No estimate. Apps outside the grossing charts, and some countries, have no reliable rank-to-revenue curve, so we show nothing rather than a guess.

How this estimate is made

Rank: we take the app's best Top Grossing rank on the latest chart day. Category ranks are converted into an equivalent overall rank, because a #10 in Finance earns far less than a #10 overall.

Curve: that equivalent rank is read off a rank-to-revenue curve anchored on public company revenue and market-data reports for the US iPhone App Store.

Country: the curve is scaled per country (Japan is roughly a third of the US, Türkiye under 1%). Where we have no scale, such as China, there is no estimate.

Range: the likely range widens with country, category and chart depth. It is a plausible span, not a statistical confidence interval.

Not included: ads, payments outside the App Store, and any difference between gross sales and what the developer keeps. Low confidence means indirect data; medium means several independent sources agree.

CarPlay Support!
NOTE: R4 Companion™ requires a Uniden R4 or R4w radar detector with US Version 142 (R4) or 127 (R4w) firmware to function correctly. R4 Companion will NOT function correctly without at least this version of firmware.

R4 Companion™ is a feature rich app, designed to give you the most out of your R4, while enhancing your driving experience along the way. Featuring intelligent alerts and advanced muting! R4 Companion™ is the COMPLETE solution to enjoying your R4.

SpotLock 2.0 and Advanced False Assist 3.0. Both data driven systems have been updated using 5 years of historical data. This takes your detector to a whole new level of quietness and safety against real threats.

The R4 Companion™ app leverages years of optimizations and features from the Radar Companion™ series of apps. (Available separately for owners of the V1, R8, R9, & DS1 radar detectors).

  • MyRadarIQ™ - Threat assessment intelligent system for the radar companion series of apps. A new meter, visible at the top of the main alert screen, will show a graphical representation of the probability of a police presence (Ka or Laser) in the direction of your travel. Using your personal alert data, whenever a high probability exists for an encounter ahead, you will know about it well in advance of facing the actual threat. The meter will go from yellow (low threat), to orange (medium threat), to red (high threat) and flash on and off and a voice announcement will occur. The meter will also flash red when a Ka or Laser alert is actively being received to help draw attention to the alert. Probabilities are calculated down to the actual day of the week you are traveling, increasing the accuracy on any given day.
  • Pair it and forget about it! It just works. *New* - Robust Bluetooth connection engine works seamlessly in the background to manage all your R4 devices.

***TIP: Setting the main volume for the detector to 0 on the main alert screen and enabling the detector alert tones, will eliminate the brief audio "blips" you would normally hear when a mute command is first sent to the detector. Only potential threats will then trigger audio through your speaker or audio system providing an extremely quiet ride.
