# PopCalculator vs Multi

The clearest difference is in-app purchases: Multi at none against PopCalculator's 1. Multi also leads on ads (none vs shown) and update cadence (every 3 weeks vs every 3 months). PopCalculator's advantage is review sentiment (100% vs 75%). On price, rating, device support and iOS requirement there is nothing between them.

Both are free to download. PopCalculator sells 1 one-off in-app purchase. Multi asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.0 for PopCalculator against 4.1 for Multi. That said, the two scores are not equally well evidenced: Multi has 14 ratings behind it against 2, so its average is the more settled of the two. Written reviews are what separate them: 100% of PopCalculator's written reviews are positive against 75% of Multi's.

PopCalculator ships an update every 3 months, Multi every 3 weeks. The most recent releases landed on September 9, 2026 and September 23, 2026 respectively.
