RowCounter is a free Android application that simplifies the process of counting rows for knitting projects. It allows you to manage multiple knit projects simultaneously and create sub-projects for each of them. Additionally, the app provides an option to prevent screen lock while counting rows and make notes in the projects and sub-projects.

One of the unique features of RowCounter is that it allows you to choose whether you want to hear a sound when you count up or down. The app also allows you to import or export projects. However, the free version only allows you to create a maximum of 3 projects/sub-projects. If you want to create more, you can upgrade to the full version via in-app purchase.

Overall, RowCounter is an excellent application for knitters who want to keep track of their projects. Its user-friendly interface and useful features make it a must-have for anyone who enjoys knitting.
