With our SIGNL4 March Update, we are speeding up and have once again completed some innovations for you. This time, we have further developed our design and color scheme slightly and made changes for better readability. In our mobile app, you can now also quickly and easily set up a stand-in, should a person unexpectedly be absent from duty. Furthermore, in certain SIGNL4 plans, the data retention period can now be flexibly adjusted to the respective company requirements.
