Oscar Wilde may have said ‘ I can resist everything except temptation , ' but he did n't have a smart safe to help him . The cylindrical device , called kSafe , keeps various forms of temptation locked away - whether it is fattening cookies , cigarettes or a time-consuming games controller . And the only way to unlock it is to reach pre-determined fitness goals , such as walking a set number of steps in a day . Scroll down for video . No more temptation : The cylindrical device , called kSafe , locks up a form of temptation - whether it is fattening cookies , cigarettes or a time-consuming games controller ( pictured ) The San Diego-based start-up behind the device said on its Kickstarter site : ‘ kSafe is part of a research proven system that turns temptation into motivation , so you always achieve your goals. ’ Users place an object of temptation into the safe and then set a goal using the accompanying app . There are three types of goals to choose from including activity goals , location goals and time goals . For example , for an activity goal , users could set the safe to unlock once they have taken a certain number of steps or burned enough calories , while a location goal may help motivate students . Strict : The only way to unlock the kSafe is to reach pre-determined fitness goals , such as walking a set number of steps in a day , which can be set and tracked on an app ( pictured left and right ) Users will place temptation into the kSafe , whether that is a bar of chocolate or iPad , for example . They will then set a goal using the smartphone app and lock the kSafe . There are three different types of choose from and the level of difficulty can be set - but not lessened once the safe has been locked . The kSafe will only unlock once a user has reached their goal . Users will be able to follow their progress on a light-up button and app . ‘ Set kSafe to only unlock once you 've arrived and checked-in to a location , like a gym or library , ' the company said . The safe will be able to be instructed to open on certain days or at certain times , which the firm added can be used to break bad habits , such as snacking between meal times . It claimed the safe ‘ crams years of willpower and behavioural research from MIT , Harvard , Yale , Stanford , and Princeton in to a fun , effective , and easy to use product. ’ It uses pre-commitment , an example of which is moving an alarm clock out of reach so the user can ’ t reach the snooze button , to make people commit to a smart choice , knowing that they 'll probably be tempted later . The device also capitalises on the idea of reward substitution , much like at school when a person may have worked hard on homework to earn going to a party . ‘ Even though making your boss happy or acing a test has more long term benefits , it 's wanting that beer with our friends that motivates us to finish , ' the company wrote . Motivational : Users will be able to view their progress in meeting their goal on the light-up ‘ button dial ’ on the top of the kSafe ( pictured ) or via the app . Compact : The safe can also be used in a conventional way using a password code to keep items safe , or off-limits to children , for example . This diagram shows its dimensions . ‘ Both of these concepts have been thoroughly researched and tested and they are consistently shown to improve our chances of reaching our goals . ' Users will be able to view their progress in meeting their goal on the light-up ‘ button dial ’ on the top of the safe or via the app . When they achieve their goal , the safe will pop open . The company said : ‘ kSafe won ’ t open until you ’ ve reached your goal . No overrides ! ’ The safe could also be used in a conventional way using a password code to keep items safe or off-limits to children , for example . As well as allowing users to check their progress , the app will let them raise the bar if they are feeling particularly motivated to burn extra calories or study into the night . But it won ’ t let users get away with making their challenge easier . The device is available in three colours : black , white and transparent , and can be pre-ordered via Kickstarter for $ 89 ( £60 ) with an estimated delivery date of November .
