A whole new world after dark

Have you ever wondered what happens in your garden after dusk?

I have. And it's fascinating!

It's also why PengyBAT exists. And why I want to share it with you.

Bats are out there, hunting and calling to each other in sounds we can't hear. PengyBAT lets you listen, see their calls on your Android phone, and find out what might be flying past.

Why I made it

Because curiosity shouldn't cost a fortune.

Bat detectors aren't new. They've been around for years — and many are expensive specialist instruments.

I thought more people should be able to enjoy this extraordinary little world. So I made PengyBAT.

I'm not trying to turn you into a bat expert. I just want you to experience the same delight I get when the garden suddenly comes alive.

Everything you need to discover bats.
Except the bats.

One price. No nonsense.

It's £39.99.
That's it.

The obvious questions

A few things you might wonder

Do I need to know anything about bats?

Not a thing. That's half the fun. PengyBAT helps you hear and explore what is happening around you, and you can learn as you go.

Does it work with my phone?

PengyBAT is designed for Android phones with suitable USB connectivity. Not every Android phone is guaranteed to work. A free, pre-purchase phone-check feature is planned; we'll explain compatibility clearly before orders open.

Can I use the app with another ultrasonic USB microphone?

Yes — the software is free to use with a compatible ultrasonic USB microphone. It must support the format and sample rate the app expects; an ordinary USB voice microphone won't do the job.

Will it tell me exactly which bat I'm hearing?

It can help suggest an identification from recorded calls, but bat calls vary and some species are difficult to tell apart. Think of it as a knowledgeable companion, not an infallible bat oracle.

Do you supply the bats?

Afraid not. They're in charge of their own timetable.
