# Hark Pro vs JellyCalc

The clearest difference is ratings volume: Hark Pro at 1.6K against JellyCalc's 3. Hark Pro also leads on update cadence (every 2 days vs weekly) and chart position (#116 vs unranked). JellyCalc's advantage is rating (5.0 vs 4.6) and iOS requirement (15.1 vs 17.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Hark Pro sells 3 in-app purchases, starting at $26.00 per month and JellyCalc sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

JellyCalc holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Hark Pro has 1.6K ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 94% of Hark Pro's written reviews are positive against 100% of JellyCalc's.

Hark Pro ships an update every 2 days, JellyCalc weekly. The most recent releases landed on October 24, 2026 and October 17, 2026 respectively.
