# Pattern Testers > Pattern Testers helps independent sewing pattern designers manage testers, feedback, files and launches in one calm workspace. Pattern Testers is a SaaS app for indie sewing-pattern brands. It replaces the patchwork of Google Forms, Facebook Groups, email threads, spreadsheets and Dropbox folders that designers normally cobble together to run a pattern test. Designers post open calls, collect and score applications, manage selected testers, gather structured feedback and photos, track issues and revisions, and ship the final pattern. ## Key pages - [Home](https://patterntesters.com/): product overview, features, pricing - [Open pattern tests](https://patterntesters.com/calls): public list of tests currently accepting applicants - [Sign up](https://patterntesters.com/signup): create a designer account (30-day free trial) - [Sign in](https://patterntesters.com/login): existing users - [Privacy](https://patterntesters.com/privacy) - [Terms](https://patterntesters.com/terms) - [Legal / Imprint](https://patterntesters.com/imprint) ## Who it's for Independent sewing-pattern designers and small pattern brands running tester rounds for PDF or printed sewing patterns.
