I've used Nozbe for a decade. It's SUPER reliable and the team behind the app is among the best in the business re: customer service.

iOS and iPadOS apps are great, they work fast, and it's easy to send pictures and documents to Nozbe. The interface is simple and clean. I like the multiple workspaces - I use one to work on my photography business and the second one for my family stuff; it's good I can easily separate them. I really appreciate the 2FA (it's a big deal in comparison to old Nozbe)

The application is very intuitive - it is straightforward and quick to start working with it. On the other hand, it has many advanced features so that even a demanding user will be satisfied. It works very fast and synchronizes well between devices. This is important for those who use the application on, for example, a computer and a phone.
