# CallRail vs Callsling

The clearest difference is review sentiment: Callsling at 67% against CallRail's 10%. Callsling also leads on monetization model (ad-supported vs freemium) and iOS requirement (13.0 vs 17.0). CallRail's advantage is rating (4.6 vs 3.9) and ratings volume (37 vs 7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

CallRail holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: CallRail has 37 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 10% of CallRail's written reviews are positive against 67% of Callsling's, so the app with the better star average is not the one people write more warmly about.

CallRail ships an update every 4 weeks, Callsling every 2 months. The most recent releases landed on October 20, 2026 and October 2, 2026 respectively.
