# Hidem vs Calculator

The clearest difference is rating: Calculator at 5.0 against Hidem's 4.3. Calculator also leads on ads (none vs shown) and iOS requirement (14.0 vs 16.0). Hidem's advantage is ratings volume (818 vs 3). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Hidem sells 9 in-app purchases, starting at $1.99 per month and Calculator sells 3 in-app purchases, starting at $6.00 per 7 days. Whichever you choose, the download price is not the number that matters.

Calculator holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Hidem has 818 ratings behind it against 3, so its average is the more settled of the two.

Hidem ships an update every 4 weeks, Calculator monthly. The most recent releases landed on October 19, 2026 and October 5, 2026 respectively.
