### 4/5 — Great App but no Print Function

*2023-03-05*

Great Application and certainly speeds up performance planning. A print function would be very useful for CAT Briefing packs.

### 4/5 — Great App!

*2021-12-15*

Use this app all the time. However it would be great to see an update to allow D3 variant data? Is there any plan in the works to see this happen?
