Significant digits in insulin entry makes it useless

Downloaded app on a recommendation. I use a pump for insulin delivery. When I entered my first correction amount of 0.475u and saved it, the software "rounds" the value to 0.5u.

Then, when I went to enter the basal profile in the software, you can only change it by the hour (pump can change basal every 30 minutes) and the smallest increment is only 0.1u whereas my pump has 0.025u increments.

Software is essentially useless as it is to me. Hopefully you will read my emails and update your software to fix this. And this was found in first 2 minutes of using software.
