Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Time Calculator × sells 4 in-app purchases, starting at $4.99 per year 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 288 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 73% 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 6 months, From Time To Time every 9 months. The most recent releases landed on October 23, 2026 and October 17, 2026 respectively.
