I’ve been using Real thermometer: Temperature for a couple months now. It’s basically a digital thermometer app that lets you track indoor and outdoor temps on your phone. Pretty solid app if you’re into that kinda thing.
Here’s what you do: you just open the app and it shows you the current temperature. And there’s also a graph to see the temperature history, which is pretty cool. And you can set alerts if the temp goes above or below certain levels – that’s been useful for me.
Look, if you’re into monitoring temperatures around your home or office, you’ll probably like this. It’s not perfect – the ads can get a little annoying if you don’t pay – but overall it does the job. Worth checking out.
