Evidently not. I never could understand the need for "to-do list" apps like Wunderlist or any others: "The app allows you to create to-do lists with optional subtasks, notes, files and comments, and set due dates and reminders for important deadlines."
So does a sheet of paper.
Nice side benefit to that sheet of paper: the paper can be folded and put in my pocket, and if I forget it somewhere I wouldn't lose my mind like if I'd lost an iPad or it got stolen.
Nor do people have the common sense to not put so much personal data "out there" for companies to data mine. Mint stands out on this list for being the most egregious - "a free app that links to your bank account". Anything that personal that is free may just be trying to get you interested in a pro upgrade, but it also means they have your information and can use it or abuse it. "Mint enables you to create budgets to help you save money." Yes, I'm sure we're all completely incapable of doing so without the "free" app. Then again, given that the article has this math lesson: "If you spend $83.33 less per month on non-essential purchases, for example, the savings quickly add up to $1,000 in one year", I imagine its directed at people who buy things they don't need when they're on sale because of all the money they save.
Even with the deep lack of common sense, I'm really surprised that there is a water-reminder app. The whole "drink 8 glasses of water a day" thing has no basis in science. You need to drink when thirsty, no more. The only time you'd ever break that rule is if you're an athlete or in a very physical job, where your effort and the environmental conditions can outstrip how fast your sense of thirst is triggered. Drinking too much water can damage your kidneys over time. Plus, if you dilute your electrolytes past a certain point, you lose consciousness and possibly die. I've been there. I changed my behavior. Didn't need an app.
Sleep Cycle is the craziest one of the bunch. Reminds me of when the Soviets used to bug diplomats' rooms in the hopes of hearing them talk in their sleep.
You would expect that these nonsense apps would have vanished after time, surprisingly the app store is (still) cluttered with these free or 0,99 kind of total crap apps. Don't understand that there are so many (excuse me: stupid) people out there which make it worthwhile for these so-called programmers to still make these apps. Browsing through the app store is just no fun as 90% of all the apps is just total junk or even worse they intend to steel your data.
