Both are free to download. Hal™ sells 10 in-app purchases, starting at $14.99 per month and Comet sells 3 in-app purchases, starting at $20.00 per month. Whichever you choose, the download price is not the number that matters.
Comet holds the better App Store score, 4.8 against 3.1.

Hal™ ships an update every 2 months, Comet weekly. The most recent releases landed on September 22, 2026 and September 30, 2026 respectively.
