What it offers
The app includes:1
- explanations of what causes cancer-related fatigue
- information on things that affect your energy, such as stress and sleep
- strength and relaxation exercises
- weekly feedback on your energy balance
What the evidence shows
In a randomised trial of the Untire app, people with moderate to severe cancer-related fatigue who used the app had less fatigue than those on a waiting list.2 The app has been available in the UK since at least 2019, when it was listed in the NHS Apps Library.3
Who it might suit
- You’re struggling with tiredness that doesn’t lift with rest.
- You’d like a structured, self-guided programme you can use at home.
Things to know
- It’s self-guided, without a coach or clinician.
- See your GP or team if you’re very tired, to check for causes that can be treated, such as anaemia or thyroid problems. See when fatigue doesn’t go away.
Other options
- Sleepio, free through Macmillan, if poor sleep is part of the problem
- Energy pacing and our 12-week strength plan
- A personalised rehabilitation programme with a coach, if you’d like more support. See digital rehabilitation.
