Is it changing? You can't tell from memory. Take the same photo every few months and compare them yourself, with the NICE checklist beside them.
How Hea helps
Mark it on a body map Today
Pick the place on a body figure, front or back, and add a note if you like. Each mole keeps its own page in your diary.
The same photos, months apart Today
Take an overview and a close-up on your phone, through a link or a QR code. Photos never go through the chat, and the hidden data a phone adds, such as where a photo was taken, is removed. Hea dates them and shows then and now side by side.
The NICE checklist, in your own answers Today
You answer the 7 questions of the checklist NICE gives GPs, about changes you've noticed. If your answers reach the point at which NICE asks GPs to refer someone with a suspicious mole, or the mole bleeds or has grown quickly over weeks, Hea tells you to book a GP appointment.
Email reminders and a dermatologist Soon
A reminder by email when the next photo is due, and your diary passed to a dermatologist.

Safety first
Hea never looks at, describes or judges your photos. If a mole changes, see your GP.
See a GP if you have a mole that's changed size, shape or colour, is painful or itchy, or is inflamed, bleeding or crusty, or if a new or unusual mark on your skin has not gone away after a few weeks.
Questions people ask
When should I see a GP about a mole?
See a GP if a mole has changed size, shape or colour, is painful or itchy, or is inflamed, bleeding or crusty. The NHS also says to see a GP about a new or unusual mark on your skin that hasn't gone away after a few weeks, or a dark area under a nail that wasn't caused by an injury.
What are the signs a mole could be melanoma?
The NHS lists a new mole or a change in an existing one, an uneven shape or edges, a mix of 2 or more colours, and a size often more than 6mm wide. Other signs are a mole that's swollen and sore, bleeding, itchy or crusty. Get any change checked by a GP.
How often should I check my moles?
The NHS says to check your moles regularly for any changes, without setting a schedule. Hea's diary suggests the next photo in 3 months for a mole you're keeping an eye on and in 6 months for others, and can put it in your calendar.
Does Hea look at my photos or tell me if a mole is cancer?
No. Hea never looks at, describes or judges your photos. If a mole changes, see your GP. Hea keeps and dates your photos, shows them side by side and asks the NICE checklist questions for you to answer yourself.
What happens at the GP appointment about a mole?
The GP asks about your health, family history and symptoms, and looks at the mole. They may take a photo to send to a skin specialist (dermatologist). If they think it could be cancer you may get an urgent referral, which does not definitely mean you have cancer.
What is the NICE 7-point checklist?
It's a checklist NICE gives GPs for a mole or other pigmented spot. It has 3 major features (a change in size, an irregular shape, an irregular colour) and 4 minor ones (7mm across or more, inflammation, oozing, a change in sensation). NICE asks GPs to use it when deciding on a referral.
