# Customer Database vs CalcBox

The clearest difference is ads: Customer Database at none against CalcBox's shown. Customer Database also leads on iOS requirement (13.0 vs 16.6). CalcBox's advantage is review sentiment (93% vs 58%) and ratings volume (380 vs 47). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Customer Database sells 8 in-app purchases, starting at $1.99 per month and CalcBox sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for Customer Database against 4.8 for CalcBox. That said, the two scores are not equally well evidenced: CalcBox has 380 ratings behind it against 47, so its average is the more settled of the two. Written reviews are what separate them: 58% of Customer Database's written reviews are positive against 93% of CalcBox's.

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on November 3, 2026 and October 30, 2026 respectively.
