cyclotest mySense Flex – Trust your cycle. For generations.
Over 130 years of experience in precise temperature measurement
Trust does not develop overnight. It grows – with every cycle, every aha moment, every temperature curve. For more than a century, UEBE Medical has been developing thermometers people can rely on. Today, this experience is reflected in every measurement with cyclotest. Fast. Precise. Reliable.
Who invented it?
In 1952, UEBE Medical developed the first thermometer with an expanded scale. This innovation made it possible for the first time to make the smallest temperature changes visible – and laid the foundation for basal temperature measurement as we know it today. Because these fine temperature differences are exactly what matters when it comes to the fertile days in the cycle. cyclotest continues to build on this pioneering achievement today.

Give your cycle the attention it deserves!

You do not have to calculate or interpret anything yourself – mySense measures your basal temperature and automatically transfers the values to the cyclotest app. This lets you see at a glance what is happening in your cycle. Simply observe – the app does the rest.
