Two separate tests for € 20 showed largely incoherent results as our test device, a Samsung Galaxy S8 was fixed in the exact same position, outdoors on a garden table with some surrounding 15 story high buildings, but still in a fairly open grass space and with strong GPS and 4G signals.

The plan was to test a number of different location apps, from a set of pre measured test spots with an accuracy of ±1% with the help of two, very standard, mobile devices under controlled circumstances. We operated the test from an iPhone XR and at 20:30 ECT the first test, 100 m from the test phone, shows a position approximately 11 km West of actual position. After around 1 hour while we conducted other tests and moved the iPhone to the second spot, now 900 m South of the test device. At 21:22 ECT the indicated location had moved 2.5 km in a North North East direction, still more than 10 km from the true location.

We decided to disqualify PatchBit from further test as the company just as well could have claimed that their software could do the laundry or bake and charge €10 for it. Of those, over 10 different apps we tested, the PatchBit application is in a league of its own where the best show positions within a few meters.

We emailed the payment support at PatchBit and made a claim for the € 20 we paid as the accuracy is far from the 50 feet that the app claimed at the time of the test. We have not heard as much as a beep, despite that the 48h service level, also mentioned in a text in the app, is long due. We didn't expect it either to be honest But the text describing the accuracy is now replaced with a *Accuracy may vary. And indeed it did!

The presentation of data would have been a nightmare as the difference in proportions of the results is as if comparing sizes between a mouse and an elephant. The conclusion is that the PatchBit operation is nothing more than a total failure and, in fact, a potential scam.
