# Time Calculator vs From Time To Time

The clearest difference is ads: Time Calculator at none against From Time To Time's shown. Time Calculator also leads on update cadence (every 2 weeks vs every 9 months) and ratings volume (2.9K vs 2). From Time To Time's advantage is review sentiment (100% vs 79%). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Time Calculator sells 6 in-app purchases, starting at $2.99 per month and From Time To Time sells 2 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Time Calculator holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Time Calculator has 2.9K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 79% of Time Calculator's written reviews are positive against 100% of From Time To Time's, so the app with the better star average is not the one people write more warmly about.

Time Calculator ships an update every 2 weeks, From Time To Time every 9 months. The most recent releases landed on October 29, 2026 and October 17, 2026 respectively.
