# Time vs Time Duration/Add Calculator

The clearest difference is in-app purchases: Time Duration/Add Calculator at none against Time's 6. Time Duration/Add Calculator also leads on iOS requirement (13.0 vs 15.6). Time's advantage is update cadence (every 2 months vs every 9 months). On price, ads and device support there is nothing between them.

Both are free to download. Time sells 6 one-off in-app purchases. Time Duration/Add Calculator asks for nothing beyond the download.

Time ships an update every 2 months, Time Duration/Add Calculator every 9 months. The most recent releases landed on September 26, 2026 and September 20, 2026 respectively.
