Solution of Ruler for iPhone 7 & 7plus: MagHolder
Although Apple removed headphone jack starting from iPhone 7, we have being trying hard to figure out a way for our customers to continue using iPin Spatial Ruler on their new iPhones. Fortunately, the new iPhone still includes a free Lightning-headphone adapter for users.
We have tested the performance of Spatial Ruler using Lightning-Headphone Adapter. The results came out to be good; pretty much the same as the one from older version iPhones.
Therefore, we design the MagHolder to tightly stick the Spatial Ruler to a fixed position defined by a stainless plate. Yes, according to its name, you know it is done by magnets inside the holder.
