### 3/5 — Hoping for updates

*2018-12-31*

I love how simple the app is, but it didn’t worked for me.
I own Powertap G3(Cadence, Speed, Power with BLE)

I hope it has...
- Able to export in TCX so you can view in Golden Cheetah 
- able to adjust Sampling rate
i know BLE can sample upto 64per second. I really hope this function exists. Many short distance riders(track sprinter) will love this function.
