Sprynkl is a free Android app developed by 2018 KMS Technology. It is designed to connect employees at all levels and build an irresistible work culture. Sprynkl is now integrated into Grove HR - an all-in-one free HR software for SMBs with more than 15K customers around the world. The app offers a range of features, including SSO via Grove HR account, peer-to-peer recognition, instant feedback, surveys, and polls.

One of the unique features of Sprynkl is its ability to connect professionals privately. With work email verification, Sprynkl only has access to trusted professionals, making it a proven place to connect people at work. Each company has its own private feed, and no external community can view or join the conversation within your company. Additionally, Sprynkl allows users to share work stories, discuss anonymously, and find like-minded coworkers.

Overall, Sprynkl seems like a promising app for those who want to build a strong work culture. However, some users may find the app's focus on company-specific communities limiting. Nevertheless, the app is easy to use and offers a range of features that can help employees connect and build relationships with their colleagues.
