## Most critical reviews (10 lowest-rated)

### 1/5 — Doesn’t work

*2025-07-18, version 1.3.4*

Last time I tried using it, every book came up for 50p on SellItBack, this time it’s 50p for every book on world of books..so scanned them on the app it said ‘50p’ for and majority it wasn’t buying at all. 
Great idea IF you can get it working properly. I’ve given up and deleted it

### 1/5 — Not accurate at all

*2025-05-21, version 1.3.4*

The app is not accurate and needs updating. Non of the books go through once you scan them

### 1/5 — Useless

*2024-11-10, version 1.2.8*

The prices were pretty much random as none of them were accurate. Waste of time

### 1/5 — Gives incorrect results

*2024-06-15, version 1.1.6*

I scanned 130 books and the app gave me prices for all of them on WeBuyBooks, but when it came to upload the books, only the first fifteen were accepted so this was a huge waste of time.

### 1/5 — Wildly inaccurate

*2024-04-01, version 1.1.5*

Gives prices over many platforms but all totally inaccurate so pointless exercise

### 2/5 — Can find the scan capability 🤷‍♀️

*2024-05-06, version 1.1.5*

Can find the scan capability 🤷‍♀️

### 3/5 — scans everything But they don’t t buy

*2024-06-14, version 1.1.6*

Great comparison options etc it’s scans everything when you go sell it to the website it uploads fine BUT they are not buying all the books this app previously marked as they will

### 4/5 — Great, mostly

*2024-12-03, version 1.2.8*

I dropped one star because, ziffit/world of books doesn’t work. The prices aren’t accurate and it will not load books on automatically you have to scan them on again. Other 3 vendors work great though.

### 5/5 — Amazing app with a couple flaws

*2024-12-16, version 1.3.0*

Fantastic app and should not be free for the value that everyone gets out of it! One of the best free apps I have ever used by a small developer.

Developer I do want you to know  sometimes the app freezes in a state where no value is given and states no company is buying the books at this time. A reboot (completely shutting down app) fixes the glitch and 90% of the time  offers around 50p from WeBuyBooks and worldofbooks (before no offers)
When I then try to scan via the actual apps it doesn’t work. But, if I input isbn number into the actual apps it will then give me the value that this app previously found.
Also, the export to the worldofbooks (previously ziffit) doesn’t work at all, but all the others do.

Hope this helps and makes the app even better! Please provide contact info as the “feedback” page doesn’t work.

Thanks so much
Harry

### 5/5 — Seems like a great timesaver.

*2024-06-01, version 1.1.5*

Layout isn't perfect, it makes it appear as if you need a companion app to scan barcode when you only need to click the 'scan barcode' icon next to where you can manually input the isbn number, but using the app to check offers has been quick and easy, showing the giving best deals from four providers, and providing other useful information. A great timesaver.
