Verdict
The clearest difference is ratings volume: Vonage Home Extensions at 4.6K against Improcom's 7. Vonage Home Extensions also leads on update cadence (every 6 weeks vs every 4 months) and rating (4.4 vs 4.1). Improcom's advantage is review sentiment (60% vs 50%). 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.
Vonage Home Extensions holds the better App Store score, 4.4 against 4.1. That said, the two scores are not equally well evidenced: Vonage Home Extensions has 4.6K ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 50% of Vonage Home Extensions's written reviews are positive against 60% of Improcom's, so the app with the better star average is not the one people write more warmly about.
Vonage Home Extensions ships an update every 6 weeks, Improcom every 4 months. The most recent releases landed on September 27, 2026 and September 17, 2026 respectively.
