A short introduction to CTLife

We're putting into your hands a brand new version of a system we've been building for over 25 years. We've packed the experience gathered over that time into a tool that lets you record and safely store fertility symptom observations and provides an automatic analysis of your fertility status. Soon it will also be complemented by automatic advice supporting your goal of caring for your procreative health.

If you link your individual accounts into a Couple, besides sharing observations you'll also be able to keep a private chat privado.

And if you're looking for a good wedding gift for loved ones, you can gift them access to ctlife as a Gift Card.

Help achieving your chosen goal

Health

Health

Taking care of fertility and health

Conception

Conception

Deepening the bond and conceiving a child

Love

Deepening the bond and postponing conceiving a child

Soon the system will also identify the most likely problems standing in the way of your goal and suggest ways to solve them.

With CTLife's help…

You'll record your observations

Temperature, mucus, and other fertility signs, from any device.

You'll get an automatic cycle analysis

Tailored to your goal: health monitoring, trying to conceive, or avoiding pregnancy.

You'll get pregnancy confirmation as early as 18 days after conception

Along with the due date and key information gathered about your pregnancy.

As a couple you'll have shared access to your cycles and your own private chat.

You'll share your data with a single code

With your instructor, NFP advisor, doctor, or midwife — or post it on a forum. The person helping you doesn't need to create an account, and you don't have to send photos of charts.

You'll see your cycle in different NFP methods

The system automatically translates the record, e.g. between the double-check (English) method and the Rötzera method. Switching methods doesn't mean losing your history.

You'll export your data to the cycle chart of your chosen method

For printing, presenting, or further work in Marker (marker.ctlife.eu).

You'll gather the data needed for causal diagnosis and treatment of infertility

Your doctor can monitor your subsequent cycles on an ongoing basis, and organized observations are the starting point for working on the underlying causes.

For NFP professionals

Do you work with NFP or causal infertility treatment?

We give you tools that simplify your work, letting you focus on giving your clients the best possible care. Once your professional credentials are verified, you get from us:

  • Everything for free. All advisor features, present and future, plus a personal account, including couple features.
  • Your practice in the system. Describe what you do: NFP, lactation, psychology, causal infertility treatment, and we'll show it on the Practices tab in the app.
  • Course panel. Manage trainings and premarital courses in one place. Track your students' progress and view their cycles if they share them.
  • A gift for your students. Course and meeting participants get 4 months of full access to ctlife, plus a fifth month from us. They learn to record their data, and you guide them along the way.
  • Marker. Your digital pen and projector. Load a chart image, add your interpretation or corrections, then send it back or show it to your students.
  • Ready-made promotional materials. Attractive marketing materials and useful links. You don't have to design a flyer from scratch.
  • An extensive knowledge base. Videos and collected information on topics you want to cover in your course but usually don't have time for.

You bridge the distance to your clients, build bonds, and stay in touch with them even after the course ends. We're building a broad community, and you — with your practice, knowledge, and experience passed on to others — are a very important part of it.

We invite you to collaborate with us!

Become an advisor

CTLife.Marker

The marker.ctlife.eu app is used for manual interpretation, replacing the previous work with paper and pencil. Mark your interpretation on any photo, screenshot, or other image, or on charts:

Seamless collaboration: paste from the clipboard, interpret, copy and send. Correct a client's interpretation in a different color and send it back within seconds.

Interactive teaching: gradually reveal the observations and then the interpretation, interpreting "live" together with course or meeting participants.

Integration with ctlife.eu: go from the app to Marker with any cycle chart.

Data security: Marker runs locally in the browser, no account required. Your intimate data stays on your device until you choose to share it.

Pricing

All services available in the system are free during the first month of use. From the second month onward, they're available as a subscription. Subscriptions can be purchased in the app after creating an account.
