Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.

About R4 Companion
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).
Enhanced GPS location based 'false muting' via SpotLocks™ - All future updates to this app are free to purchasers of R4 Companion™

• Ability to set R4’s internal detector settings from the app. *Requires US Version 142 (R4) 127 (R4w) firmware.
• SpotLocks™ works seamlessly with your R4’s built in 'auto mute memory' locations. If you create or delete a location from the app it will apply the changes to your R4 at the same time.
• 'Proximity' meter - leverages the high resolution signal strength to show you a better representation of the signal's source.
• 'K & X falses in area' meter shows you how many possible false alerts exist in the area you are traveling based on the accumulated SpotLock data™.
• 'Custom Phrases' for a given threat's audio announcements.
• High resolution meters for the priority alert (Not limited to the # of bars on the R4 display).
• Customizable heads-up display (HUD).
• HUD displays the priority alert's band, signal strength, frequency. The HUD is color coded between real threats & muted false signals.
• HUD of the secondary alerts' bands, signal strengths, frequencies, & bogey counts.
• Advanced BSM/CAS/Ka False Muting (Optimized for the R4 platform).
• 'Ghost' muting quiets false alerts when you are stuck traveling near a false emitting vehicle.
• "Passive Mute™"- Quiets the R4 below user set speeds & durin
