Even a houseplant needs a gadget. If you have a black thumb like us, your plants will thank you for this little guy.
Dr. Frog monitors your plant's soil and lets you know when it needs more water. It reportedly lets out a little croak when its thirsty. This could be annoying, or could be enough of a motivation to get you in the habit of watering your plants. At the very least it has a light sensor to disable the croaking cry at night. So if your plant goes dry in the middle of the night, you wont have to wake up to water it. Lets just hope it reminds you in the morning.
