1/5Run, don't walk away from this app!
I purchased this app to keep track of my ever-growing book collection. It seemed like a great solution. I ordered most of the in-app purchases which was stupid on my part. In order for the app to be useful the database sync/backup in-app purchase would be essential. Here's where the problem began. In order to do this you need to authorize thru Facebook. I tried to do this repeatedly but the process went into an endless loop and wasn't able to be completed. There was supposed to be an alternate way to set-up the sync if you didn't want to or couldn't use Facebook but in actual practice this was never offered to me. I sent the author two emails and made one phone call to explain my problem without any response. Save your money and stay away from this program.

1/5A Rip-Off!
The free *trial* of this app that allows you to scan a limited number of barcodes to show you how everything works, worked perfectly. So, I decided to pay the $.99 for the app. THEN once I did that, I was prompted to pay another $.99 for the barcode scanner. So, I did that too. THEN when I opened the app again to scan more books, the ones I’d already scanned disappeared. It gets worse. You see a list of tabs in the settings section but the only one you can click on is the one that takes you to literally pay for every single feature the app offers, which should’ve been included in the $2 I already paid. $5 for a CSV export, and $5 for auto input of the books details, etc. This is literally a rip-off app that baits you with a perfectly working demo, but then SURPRISE nothing works unless you pay nearly $20 for all the standard features.

4/5Great support
I love how this app let's you browse books within the app, as well as keeping all of my future and finished books in one place. I had a mishap from not remembering my original sign in that seemed to delete all of my books. I wrote the company and they quickly responded, having already migrated all of my books to my new sign in. I was very happy and impressed with the speedy thorough support, as well as feeling more comfortable about the security of my days. Nice.

5/5Deceptive
I am sick of this app. Even after you do the in app upgrade, every time you go to options it continues to blink at you like you haven’t purchased anything. I think I’ve accidentally “purchased“ this app upgrade three times now, which I suppose technically is my fault but they keep screaming at you to upgrade even after you have. You can’t turn it off. Plus it’s just erased all my books and apparently the only way to sign in to retrieve them is by using Facebook, which most of us would prefer her not to use as a login. Some other option ought to be available on this also. The app itself works fine but I’m tired of the deceptive in app purchase bit that they have never corrected. So I’ve ( reluctantly ) deleted the app. ( Apple helpfully gave me a refund on this “upgrade” also). Hope this helps somebody.

5/5Excellent Support
I bought this app several years ago and at the time had an iPhone 4S. I had a collection of over 200 motorcycle books and relied on this app to remind me of what I had when looking at new possibilities. As the app was revised, it required IOS 10, but my 4S stopped updating at iOS 9. Once I updated to an iPhone 8Plus, I contacted the app developer and explained that I could not get the app to load my library history. Within 12 hours I was contacted by him and told that the history files were reset so that they could now be imported directly onto my new phone. I followed his directions and all of my book collection was restored. Many thanks!

I had a mishap from not remembering my original sign in that seemed to delete all of my books. I wrote the company and they quickly responded, having already migrated all of my books to my new sign in. I was very happy and impressed with the speedy thorough support, as well as feeling more comfortable about the security of my days. Nice.",

I think I’ve accidentally “purchased“ this app upgrade three times now, which I suppose technically is my fault but they keep screaming at you to upgrade even after you have. You can’t turn it off. Plus it’s just erased all my books and apparently the only way to sign in to retrieve them is by using Facebook, which most of us would prefer her not to use as a login. Some other option ought to be available on this also. The app itself works fine but I’m tired of the deceptive in app purchase bit that they have never corrected. So I’ve ( reluctantly ) deleted the app. ( Apple helpfully gave me a refund on this “upgrade” also). Hope this helps somebody.",

          "body": "I bought this app several years ago and at the time had an iPhone 4S. I had a collection of over 200 motorcycle books and relied on this app to remind me of what I had when looking at new possibilities. As the app was revised, it required IOS 10, but my 4S stopped updating at iOS 9. Once I updated to an iPhone 8Plus, I contacted the app developer and explained that I could not get the app to load my library history. Within 12 hours I was contacted by him and told that the history files were reset so that they could now be imported directly onto my new phone. I followed his directions and all of my book collection was restored. Many thanks!",
