No there is no smartphone app with the 10hz accuracy of a dragy GPS device, smartphone GPS has a resolution of 1hz.Those are good times! Good to hear you're satisfied with the ABT box. But you still want it to be faster, haha.
By the time my tune was ready sadly there was no opportunity to do a Dragy test because it was rush hour. My tuner told me to expect acceleration times 0-100 km/h in 3.x seconds and 100-200 km/h below 10 seconds. I don't have a Dragy myself. I wonder if there is a free Android app that gives reliable test results?
Your tuner is correct, id reckon you will see 0-100 in region of ~3.6-3.7 and 100-200 ~9.5-9.8 based on others with these cars when 'properly' tuned.
Its going to be quick. TVS cars are usually very quick
