What the evidence shows

In 2020, the Scottish Health Technologies Group reviewed OWise. It found that people described their experience of using the app as positive, but that there were no published studies reporting health outcomes, and it was unclear whether it saved costs.²

Who it might suit

You’d like to keep track of side effects and appointments in one place.
You find it hard to remember how you’ve been between appointments.

Things to know

A tracking app doesn’t replace contacting your team. If you have signs of infection or feel very unwell during treatment, call your acute oncology or chemotherapy helpline straight away.
Check the app’s privacy information before entering health details.
