This is the free version of BeeCount. Its got the same functionality as the paid version with one exception - only one project at a time may be stored.
BeeCount is a knitting row counter designed to keep track of multiple "counts" within multiple (paid version only) knitting projects. BeeCount makes few assumptions about the nature of the project, instead allowing you to customise each project to best suit what you are knitting.
Each count in a project can have multiple alerts and can be linked to other counts to increase or decrease them. Counts can also re-set themselves at a particular value.
BeeCount has a community on the popular Ravelry website where support can be obtained.
