Verdict

The call

The clearest difference is review sentiment: Production Time Study at 100% against Sampling Calculator's 50%. Production Time Study also leads on update cadence (every 2 months vs every 16 months) and ratings volume (115 vs 1). Sampling Calculator's advantage is rating (5.0 vs 4.6). On ads, in-app purchases, monetization model and chart position there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Sampling Calculator holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Production Time Study has 115 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 100% of Production Time Study's written reviews are positive against 50% of Sampling Calculator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Production Time Study ships an update every 2 months, Sampling Calculator every 16 months. The most recent releases landed on September 8, 2026 and September 10, 2026 respectively.
