### 4/5 — Can we export the data?

*2024-11-13*

Can you make it so the data can be emailed or exported? If you did, I’d buy more chronographs and probably even pay for the extra capability for the app.

### 4/5 — Please add a way to export data

*2024-04-30*

Good app overall to record my chronograph readings however, I would appreciate if there was a way to export the data into a spreadsheet or even just the clipboard. Works well!

### 3/5 — Pretty good

*2020-02-11*

Can set the exact size and weight of gel ball or bb with this app. It has a history graph for single statistic or all stats like FPS R/S M/S FT J J/CM. It displays battery level and has an instructional tab very easy to understand. But that’s it pretty basic. I’d like the option to change the display lights from app and the device name.

### 2/5 — Connection

*2019-02-06*

I have 2 iPhone 7+ and will not connect to them
