# Portable Inventory vs Customer Database

The clearest difference is rating: Customer Database at 4.6 against Portable Inventory's 4.1. Customer Database also leads on iOS requirement (11.0 vs 13.0). Portable Inventory's advantage is review sentiment (73% vs 58%) and ratings volume (220 vs 47). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Portable Inventory sells 3 one-off in-app purchases and Customer Database sells 8 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Customer Database holds the better App Store score, 4.6 against 4.1. Both are backed by a comparable volume of ratings — 220 and 47 respectively. Written reviews complicate that: 73% of Portable Inventory's written reviews are positive against 58% of Customer Database's, so the app with the better star average is not the one people write more warmly about.

Portable Inventory ships an update every 3 weeks, Customer Database monthly. The most recent releases landed on September 22, 2026 and September 9, 2026 respectively.
