This is a super app that does exactly what it says and is a great help to my business. Instead of hand-writing or printing out pick slips, we just carry our phones to the warehouse and check off items as we select them. Packing can even check them off as packed, so you know right where your orders are in the shipping process.
We are working on becoming a B Corp, which involves producing less waste and being gentler on the environment, so not having to print pick slips is a great step for us!
I love that after a couple of weeks, Evgeny from TG emailed to see how it was working for us and helped me use it more efficiently. That's great service. I have made one request for a future update, which I see in other reviews as well: the ability to click into an item's description to get more info if needed. We love it even without that, though.
Update: We've been using this app for quite a long time now, and I want to let everyone know that it is absolutely indispensable to our business! One of the few apps we can't do without. I can't recommend it highly enough!
