I absolutely LOVE the idea of creating a book out of text messages, and just ordered one for my sis. I tried to do it manually using a PDF file from my iMessages on my Mac, but that was totally impossible. Keepster just automatically formats everything, and the book looks beautiful in the images. It's the perfect gift, especially in this COVID year! Only reason I didn't give a 5 is that it seems silly to not be able to use the iMessages file that's already on my Mac. I sync texts to iCloud and then delete from my phone, so I had to sync ALL my texts back to my phone, back that up to my Mac, and then create the book. Other than that, the app was a dream to use, and when I got stuck, I was able to get help really quickly using the chat feature. I'll definitely use Keepster in the future!
