Smaart RTA downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. iPhone downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.
Active users
All platforms, worldwide. Free with an account.
Stickiness (DAU / MAU)
how many monthly users open it on a given day
How this is calculated
Monthly users come from lifetime installs across every store, fitted on monthly active user figures companies publish; daily users = monthly × the typical daily/monthly ratio for the category. Confidence is the chance the real number is within half to double ours.

About Smaart RTA
Professionals and enthusiasts alike can now access Smaart’s Real Time Analyzer, beautifully rendered Spectrograph, and crystal clear SPL meter without needing to set up a dedicated personal computer to run a desktop version of Smaart*.
Smaart RTA is capable of the same accuracy, precision, and ease of use enjoyed by live sound engineers and FOH professionals across the world using the same underlying algorithms as its desktop siblings*, trusted by sound engineers to deliver accurate and actionable data in real time.
*PLEASE READ Smaart RTA creates single channel measurements only. It does not support the dual channel transfer function measurements or impulse response measurements used for system alignment and optimization, including time alignment.
-- SMAART RTA INCLUDES --
-PROFESSIONAL STANDARD RTA (REAL TIME ANALYZER) GRAPH-
The RTA display helps engineers ensure an audio mix or playback balance aligns with the desired tonal response for a specific artist, performance, or specification – providing real-time analysis of frequency content and confidence that you are hearing what you are seeing.
Features include:
Fast, Slow, None averaging options for graph response ballistics.
1/48, 1/24, 1/12, 1/6, 1/3, 1oct Banding for precision frequency resolution.
1/3 octave x-axis frequency scale for intuitively identifying center frequencies and trends.
-BEATIFULLY RENDERED SPECTROGRAPH-
The Spectrograph is essential for managing and controlling feedback and identifying problem frequencies, allowing engineers to quickly visualize and address potential issues before they interfere with a performance.
Features include:
Adjustable dynamic thresholds to customize the amplitude levels represented by the spectrograph.
1000 slices in history, allowing you to ‘rewind’ the display to view events that already happened.
Intuitive color palette to represent amplitude level (dark to bright, quiet to loud).
-CLEAR SPL DISPLAY WITH DB LEVEL METER-
The SPL view helps you ensure audio levels remain consistent from one show to the next or check levels for uniformity across various locations within a venue.
Features include:
Standard SPL metrics of A & C weighting, with fast and slow response times.
NIOSH and OSHA exposure percentages correspond with nationally accepted U.S. recommendations and occupational health and safety guidelines.
Large Level Meter display for distant viewing.
The default settings for all functions in Smaart RTA mirror those in the desktop version of Smaart v9’s real time single channel measurements.
-- ADDITIONAL SMAART RTA PRO FEATURES --
Smaart RTA Pro includes the functionality of Smaart RTA and unlocks all settings and advanced features, including:
Adjustable RTA Graph Settings (frequency scaling, bars/lines, line thickness, grid interval, etc)
Plot Calibrated Levels to view the RTA graph relative to SPL, rather than Full Scale level only.
Target Curves (Cinema X Curves included, or import your own).
