Tremor12 on iPhone

Has anyone here used a tremor measuring application on their smart phone? An APP called Tremor 12 already exists for iPhone users. , But I don’t know if there is an equivalent android-based application?

Such an application would be of great assistance to sufferers of Parkinson’s in continuously monitoring the condition and might yield useful reproducible information about their response to medication for example.
It would have to be simple to use and give clear indications of the condition at regular intervals and also permit the patient to give useful feedback to medical professionals rather than anecdotal evidence?
Perhaps this might be a suitable development project for Parkinson’s UK to sponsor?
