20.Do you find it difficult to put down your mobile phone?If your answer is yes,you're not alone.These days,many people can't live without their phones.They reach for them as soon as they wake up in the morning.They keep checking their apps,such as QQ and WeChat,to get the latest news. It may be difficult for these people to give up the bad habit,so Google developed an app called Dashboard to help them.This app helps users manage the time they spend on their phones. First,Dashboard allows the users to look at their phone habits.For example,users can see how many times they have unlocked their phones,how many times they have checked their apps,and how much time they spend on each app each day.Once the users see this information,they will be able to make some changes.They can set a time limit (限制) for how long they can use each app every day.After they've hit the limit,they won't be able to use the app until the next day.What's more,Dashboard can help keep the phones silent when users put their phones face down,so they will use the phones less. If you truly want to make full use of your free time instead of spending hours using your smart phone,this new app is just a good choice.After all,controlling yourself and having a strong will can help you most.
