Agreed. The iWatch (not cheap, natch) does an ECG, so this should be doable on an iPhone in software, ergo no patent should be allowed (in the current right-pondian world, at least). The idea seems to be "apply a mathematical algorithm to a collected ECG trace to determine blood-glucose levels".
You can get an ECG device for ~£100 on Amazon, possibly down to around £50 so just need the data feed from that
