# ProjectorCalc vs productionTimer

The clearest difference is review sentiment: productionTimer at 90% against ProjectorCalc's 38%. productionTimer also leads on update cadence (weekly vs every 49 months) and ratings volume (13 vs 2). ProjectorCalc's advantage is price ($2.99 vs $19.99) and rating (5.0 vs 4.7). On ads, in-app purchases, monetization model and device support there is nothing between them.

ProjectorCalc costs $2.99 and productionTimer $19.99 up front. Neither carries in-app purchases, so what you see is what you pay.

ProjectorCalc holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: productionTimer has 13 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 38% of ProjectorCalc's written reviews are positive against 90% of productionTimer's, so the app with the better star average is not the one people write more warmly about.

ProjectorCalc ships an update every 49 months, productionTimer weekly. The most recent releases landed on October 31, 2026 and November 1, 2026 respectively.
