# OneMessage vs Call.com

The clearest difference is in-app purchases: OneMessage at none against Call.com's 33. OneMessage also leads on rating (5.0 vs 4.6) and iOS requirement (13.0 vs 16.4). Call.com's advantage is update cadence (every 10 days vs every 4 months) and ratings volume (742 vs 2). On price, ads and device support there is nothing between them.

Both are free to download. Call.com sells 32 one-off in-app purchases. OneMessage asks for nothing beyond the download.

OneMessage holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Call.com has 742 ratings behind it against 2, so its average is the more settled of the two.

OneMessage ships an update every 4 months, Call.com every 10 days. The most recent releases landed on June 1, 2026 and September 25, 2026 respectively.
