For all other CEL-FI products, use the CEL-FI WAVE app. The WAVE PRO app and CEL-FI COMPASS combine to facilitate and optimize CEL-FI and SHIELD installations.

Connect your COMPASS to a CEL-FI QUATRA system to Activate/Deactivate it, update software, or change Antenna, Band, and Channel settings.

Verdict
The clearest difference is rating: CEL at 4.3 against MobileOSS's 1.5. MobileOSS's advantage is update cadence (monthly vs every 2 months) and review sentiment (11% vs 0%). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
CEL holds the better App Store score, 4.3 against 1.5. That said, the two scores are not equally well evidenced: MobileOSS has 40 ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 11% of MobileOSS's written reviews are positive against 0% of CEL's, so the app with the better star average is not the one people write more warmly about.
MobileOSS ships an update monthly, CEL every 2 months. The most recent releases landed on September 21, 2026 and September 10, 2026 respectively.
