The UK numbers of daily users playing the monster-hunting app on iPhones has tumbled from of a peak of 1.7m to around 53,000, according to analyst firm Mobile Action.
This mirrors a worldwide trend that has seen the game lose more than 15 million users since it was sensationally launched in July.
Despite being crowned 2016’s biggest mobile game by Google, critics claim a lack of development is the chief reason for its rapid downfall.
The game was hugely popular following its release with thousands of people roaming their communities in search of the little monsters.
At its height the majority of 18 to 24-year-olds played the game for almost an hour a day, according to one poll.
Despite being praised by some for getting people outside it was also plagued with controversy after reports emerged of players being stabbed and mugged.
However it seems the game’s repetitive nature and a lack of Pokemon characters to catch are the main reasons behind its downfall.
It has also been beset with numerous technical problems which weren’t immediately fixed.
In a bid to remedy its ailing fortunes the app’s developer Niantic is widely rumoured to be releasing an update later this month.
Greg Slabaugh, a senior lecturer in computer science at City University, said: “They could re-engage some interest but I’m doubtful the game will regain its former popularity. It was a bit of a fad to be honest.
“That said, their revenues from in-app purchases have help up much better than user numbers, so if they can keep some people playing, it can remain a big commercial success.”
