London: Now your garden plants need not die of neglect, thanks to an iPhone application that tells you when they need watering.
The Koubachi Wi-fi plant sensor and application costs a steep 99 pounds. It requires a sensor which sits with the plant, monitoring it and checking its vital signs against a built-in botanic encyclopedia.
The app knows everything about nearly all your typical garden or house plant, from growing seasons to optimum temperature.
The health metrics are sent over as messages to your iPhone, and your phone will beep whenever your plant hits the danger zone, according to the Daily Mail.
The device was built by alumni of technical universities in Switzerland and Germany, and can monitor several plants at once.
It spends a few days calibrating itself, and after that it can be left alone, powered by two AA batteries which will last about 18 months.
“We knew of the importance of bullaun stones and that it could be a really significant find,” the BBC quoted him as saying.
“Our head of archaeology confirmed a possible link to the stone at the cross and I was so excited that I went back out at 9pm that night to check whether it fitted the stone with the hole and it did,” he said.
Katherine Forsyth, an expert in the history and culture of early Celtic-speaking peoples, based at the University of Glasgow, described it as an “amazing find”.
“Stones like this are found in Ireland, where they are known as ‘cursing stones’, but this is the first to be discovered in Scotland,” she said.
“They date from the early Christian period but have continued to be used by pilgrims up to modern times.
“Traditionally, the pilgrim would recite a prayer while turning the stone clockwise, wearing a depression or hole in the stone underneath,” she said.
Dr Forsyth said bowl-shaped lower stones had been found elsewhere in Scotland, including on Canna, but this was the first discovery of a top stone.
“This exciting find provides important new insight into religious art and practice in early Scotland and demonstrates just how much there is still to be discovered out there,” she added.
