### 4/5 — Simple but Really nice graph

*2026-01-12*

Not much here, just test entry.  The data entry process is nicely executed and streamlined, far better than others I tested. a pretty nice graph is provided which has a nice feature that allows you to view the projected results based upon the curve. However a major downside is that it is lacking heart rate data entry.
