Review momentum
45/100
faster than 42% of Productivity apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
What users say about Amount - Unit Converter
From the 50 most recent App Store reviews in the US.
Users appreciate the app's clean interface and extensive unit coverage but are frustrated by outdated UI elements that conflict with modern iOS features like Dynamic Island. There is significant anger regarding the developer abandoning this version in favor of a paid 'Amount 2' update, leaving existing customers with broken currency conversions.
Mixed but leaning positive (62% of recent reviews give 4–5 stars). People like it for being easy to use, and its design. The main complaints are about recent updates, and price and subscriptions. Recent reviews are more negative than earlier ones.
What people like
- Ease of use: “Easy to customize--the units”
- Design: “Clean interface, Fast conversion”
- Features & content: “Excellent Conversion Tool”
- Updates: “Wish there is a button to update exchange rate faster”
Common complaints
- Updates: “Coding error for uploaded update?”
- Price & subscription: “Don't pay for the app because you might get left behind”
- Crashes & bugs: “iPhone 6 9.1 & it doesn't work”
- Design: “There seems to be an assumption by the designers that everyone will know how to us it by opening it”
