Excellent app for birdwatchers!!!

Hi guys I am a young birdwatcher and my biology teacher is teaching me how to be a great birdwatcher. So she told me to install this app and I got to learn how to use in 2 minutes!!! I wouldn’t be able to be a birdwatcher without this app!!! It is a marvellous app and I hope you enjoy it as well. I just wanted to say that could you make an update in which we can save the birds we saw before??? Also could you please update that if I don’t use this app for 5 days it will still be on??? Because one time I didn’t use the app for 5 days and I had to submit my gmail address.

I am embarrassed

I am 38 & 120 months old and I can sadly admit I have no idea what wildlife we have near me. For the first time in my life I am wondering what “Bird” or “Tree” is that. I really can not tell the difference between an Oak Tree or Birch (I had to search the internet for another name, that’s how bad I am) I have no ideas what type of seagulls are pinching my chips (Not the swear name I give it). I would love to know what types of bird of prey I have near me.

This app is Idiot Full proof. How do I know? I can use it! I take a photo or answer questions if I’m not close enough and it tells me what the possibilities are or by the photo, a match.

It has encouraged me to buy a DSLR camera and a pair of Binoculars. I am off to Scotland this weekend to see what wildlife is near my son.

I wish this was available when I was young!!

Thank you and don’t hesitate to test my review. It really is that good.

What can I say!!

If you’re a seasoned pro bird watcher or a novice, this app is perfectly suited to everyone. The gps system is top notch, being able to see what birds I’m likely to see & their individual calls, songs & detailed info & when, where you will see them, if they are resident birds or migratory. The photos are clear. You can download bird packs for different countries & what birds they have! All this in the palm of your hand!! Marvellous & I love it..
