Good app.

Too many things require to be paid. Like compass, metal detector, and others. Amazon makes more money.

Paul Barbeau


This is a great app. I tried to buy the pro version, but it would not let me.

Jeffrey Dixon

Dog whistle still unusable

The dog whistle will not work right.once started you must force close app to make it stop,even muting column does nothing, other tools are sometimes fine but other times malfunction so you can't trust the results.

John Reeves

Flagged as a Trojan variant

ESET flagged this as really risky app. My friends phone flagged it the same too. What's up with that? Trying to steal info!?

Olatunde Baba


A lot of pop ups, too high tech for many devices, otherwise excellent.

Carl Olsen

Novelty junk

I loaded this on my S5 thinking it would be useful but most of it is just novelty junk that has no accuracy or real benefit

Sgh Horlick

Mostly useful

Could use some use documentation within app.

Josh Stacks

Good app.

I use the dog whistle the most.. I don't own a dog but it keeps the kids busy looking for that sound..
