# aTimeLogger vs ChartDay

The clearest difference is monetization model: ChartDay at freemium against aTimeLogger's subscription. ChartDay also leads on rating (5.0 vs 4.7) and review sentiment (100% vs 86%). aTimeLogger's advantage is ratings volume (303 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. aTimeLogger sells 11 in-app purchases, starting at $5.99 per month and ChartDay sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

ChartDay holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: aTimeLogger has 303 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 86% of aTimeLogger's written reviews are positive against 100% of ChartDay's.

aTimeLogger ships an update fortnightly, ChartDay every 3 weeks. The most recent releases landed on October 20, 2026 and October 6, 2026 respectively.
