# iCalc vs Nest Chat

The clearest difference is rating: Nest Chat at 4.9 against iCalc's 4.4. Nest Chat also leads on iOS requirement (14.0 vs 16.0). iCalc's advantage is ads (none vs shown) and ratings volume (354 vs 22). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. iCalc sells 13 in-app purchases, starting at $0.99 per month and Nest Chat sells 2 in-app purchases, starting at $5.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Nest Chat holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: iCalc has 354 ratings behind it against 22, so its average is the more settled of the two.

iCalc ships an update weekly, Nest Chat fortnightly. The most recent releases landed on September 20, 2026 and June 2, 2026 respectively.
