# CallApp vs Viva Prompter

The clearest difference is in-app purchases: Viva Prompter at none against CallApp's 13. Viva Prompter also leads on ads (none vs shown) and rating (5.0 vs 4.6). CallApp's advantage is ratings volume (715 vs 1). On price, review sentiment and device support there is nothing between them.

Both are free to download. CallApp sells 8 in-app purchases, starting at $6.99 per month. Viva Prompter asks for nothing beyond the download.

Viva Prompter holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: CallApp has 715 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 57% of CallApp's written reviews are positive against 50% of Viva Prompter's, so the app with the better star average is not the one people write more warmly about.

CallApp ships an update fortnightly, Viva Prompter weekly. The most recent releases landed on September 21, 2026 and June 2, 2026 respectively.
