Very comprehensive roasting app w data logging

I home roast with a Hottop roaster which I have added 2, (K-type) thermocouple heat probes through the bean chute. I purchased the Thermoworks BlueTherm which my two probes plug into. The BlueTherm sends the temps via bluetooth to my iPad running Roastmaster to log the two temps as the roast it in progress. This works very well indeed. Also the myriad of features Roastmaster sports. Inventory, cuppings with time stamp, blending. But the roast in progress graph page is outstanding. You can watch delta rate of temp rise, time since first crack, temp projection markers for temps, you can scroll through pervious roasts which will underlie the current roast in progress for comparison. I also have fan and power settings I can add on the fly with a handy pop-up keypad. This keypad also works with no data logging for temps. Tops scores for me. Incredible connivence having my entire coffee world on the iPad. I roast almost every day.
