# AT vs 할일

The clearest difference is ads: AT at none against 할일's shown. AT also leads on update cadence (every 2 weeks vs every 7 months) and ratings volume (394 vs 7). 할일's advantage is review sentiment (96% vs 77%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. AT sells 10 one-off in-app purchases and 할일 sells 1 in-app purchase, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.

AT holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: AT has 394 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 77% of AT's written reviews are positive against 96% of 할일's, so the app with the better star average is not the one people write more warmly about.

AT ships an update every 2 weeks, 할일 every 7 months. The most recent releases landed on October 14, 2026 and October 5, 2026 respectively.
