4/5App interface
I enjoy the access afforded with the app though there are a couple of places you aren’t able to make changes under the SALES>SALES ORDERS tab: cannot alter these items- shipped qty, order stage. Also, the customer address does not show. Still, I enjoy its use.

5/5Glad We Can Scan
The app is decent, but with no auto update on the cache it is difficult to ensure your getting the most updated information every time you open the app. Also with a growing company to update the cache takes longer and longer. There are also some functionalities that the website has that the app doesn’t that would be useful. Such as the items showing that they are on a PO but you’re not able to click on the PO or SO to show what PO they are on. So updating some features and the automatic cache would be nice to have.

3/5Decent, underwhelming
I like SOS quite a bit but I feel like the user interface on the app is not as straightforward and well designed as it could be. Though I will say it is nice that there is full functionality. A better user interface would result in 5/5 star.

1/5Mobile app is terrible
Mobile app is terrible going on several years. Auto cache update is a must yet they refuse to implement it. If you want to waste an hour waiting on the cache to update this is the app for you. Terrible!

1/5Needs work
Not easy to navigate. Need thumbnails on items. Needs to update automatically and instantly.
