Verdict
The clearest difference is in-app purchases: Powertime at none against Call.com's 33. Powertime also leads on iOS requirement (11.0 vs 16.4). Call.com's advantage is update cadence (every 2 weeks vs every 3 months) and ratings volume (821 vs 9). On price, rating, review sentiment and ads 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. Call.com sells 32 one-off in-app purchases. Powertime asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.6 for Powertime against 4.6 for Call.com. That said, the two scores are not equally well evidenced: Call.com has 821 ratings behind it against 9, so its average is the more settled of the two. Written reviews are what separate them: 42% of Powertime's written reviews are positive against 39% of Call.com's.
Powertime ships an update every 3 months, Call.com every 2 weeks. The most recent releases landed on October 23, 2026 and October 27, 2026 respectively.
