### 5/5 — App works great, visually noisy user interface

*2026-05-11, version 3.6.0*

I needed to do a bunch of dollar amount conversions over different years. Every time I changed a year, the keyboard would dismiss, the spinners, and the text field would move around under my fingers, making it difficult to re-orient myself and figure out what’s going on. And then when I enter entered a dollar value, the keyboard would appear and then compact the UI. It would be a much more pleasant experience if the keyboard were always present, and the user interface was rock stable while doing several conversions that’s spanned several years

### 4/5 — Super useful

*2025-02-22, version 3.5.0*
