# AQL vs TimeCalc

The clearest difference is rating: TimeCalc at 4.5 against AQL's 3.3. TimeCalc also leads on update cadence (every 5 weeks vs every 19 months) and review sentiment (79% vs 50%). AQL's advantage is in-app purchases (none vs 4) and ads (none vs shown). On price and device support there is nothing between them.

Both are free to download. TimeCalc sells 4 in-app purchases, starting at $0.99 per month. AQL asks for nothing beyond the download.

TimeCalc holds the better App Store score, 4.5 against 3.3. That said, the two scores are not equally well evidenced: TimeCalc has 90 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 50% of AQL's written reviews are positive against 79% of TimeCalc's.

AQL ships an update every 19 months, TimeCalc every 5 weeks. The most recent releases landed on October 23, 2026 and October 24, 2026 respectively.
