You've watched the hard days take a toll on everyone

The meltdowns that seem to come out of nowhere
The family moments cut short
The stress that settles over the whole house

You've looked for help, but the usual path means months of waiting and a lot of talking about feelings.

There's an earlier, easier place to start, one your child will actually want to use.

Mightier is a heart sensor and a library of games that turn calming down into the way you win.

Will my kid even play it?

They want to, that's the design.
And if not, there's a 90-day money-back guarantee.

Is it a hassle to set up?

Put on the sensor, press to pair, done. Not a techie? Neither are we.

Is my family's data private?

Mightier never sells or shares your child's or your family's data.

Off-screen activities mailed to your home each month

New hands-on activities in the mail each month, crafts, games, and stories built around a feeling like anger or worry. Same skill-building, off the screen.

Screen-free, table-friendly, and surprisingly fun for grownups too.
