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

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 iCluster - DX-Cluster database
THE ORIGINAL DX-CLUSTER APP
iCluster is an iPhone and iPad App for HAMs, SWLs (Short wave radio listeners) or for everybody who want’s to know, what’s going on on the amateur radio frequencies.
This App is connecting the so called international DX-Cluster database in realtime. The results are analyzed and displayed in an easy to read overview.
The content can be filtered by frequency (e.g. 80m, 40m etc.) or mode (CW = Morse, Beacon or digital modes), Call Prefix, ITU/CQ Zone, Country and many more.
Calls (the callsign of the operators) will be decoded automatically by the App. This allows even inexperienced users to know the countries of the operators.
iCluster is an ideal tool for amateur radio operators for field days or contests. But also unlicensed users can use iCluster to find out the frequencies for their shortwave scanner or short wave radio receiver.
MAIN FEATURES:
■ Real time DX-Cluster database
■ Several pre-defined Cluster Servers
■ Easy to add your own Server (e.g. CW-Skimmer)
■ Several Filter and Filter combinations
■ Several Alarm settings
■ QRZ.com (Database!) lookup
■ QRZ.com website lookup
■ HamQTH lookup
■ Display whole cluster on a Map (Globe)
■ Display single Spot on a Map (Globe)
■ Shows distance and bearing from own location
■ iCloud Synchronization
■ UTC Clock
■ No HAM license or registering required

This App exists since the App Store Exists as this was my first App. It has been continuously improved and re-written several times and is now available as Version 12, written in Swift 5.
It's interesting to see how many other bad copies of my App are available on the App Store. If there is another DX-Cluster App, offering features my App is missing, just let me know.
