Tips for you, based on your pace towards your goal
On track, or a little behind? You'll know.

adjust in the afternoon, not regret it at night.

Add a glass straight from the Islet Water widget on your Home Screen
Steps and weight sync with Apple Health, so there's no double logging
Your plan
Targets made for your body
Islet builds your plan around protein, fibre and water, not just calories.
A plan in under a minute
Tell Islet your height, weight and goal. It works out daily targets for you, shows your first
milestone and roughly when you'll get there.
Protein with a range to aim for (for example 82 to 109 g)
Fibre: a daily target to round out your meals
Calories as a guide, not a limit
Water set to a target that suits you
Targets adjust as your weight and activity change
Food logging
Log food your way
Logging should take seconds, not willpower.
Premium
Just tell Islet what you ate
Type "I had a chicken wrap and a flat white for lunch" and Islet AI logs both, with calories and
protein, and tells you where you're at for the day.
Ask questions in your own words, like "How am I going with protein this week?"
Get a practical nudge back, such as when in the day you tend to fall short
Prefer the classic way? Search foods, scan a barcode or snap a photo,
and star the foods you eat often so they're one tap away next time.
Medication tracking
Every dose, in one place.
Take a weekly medication? Islet keeps your doses, injection sites and notes together.
Not taking one? Skip it, and everything else works the same.
Know your dose, week by week
Islet estimates your medication level through the week from your own dose log, so you can see
how it changes through the week, next to your own notes.
Today's estimated level, with the week's peak and lowest
Zoom from one week out to one month, three months, six months or all time
A heads-up on injection day
Rotate sites, note how you feel
Tap a spot on the body map or pick from the list. Islet remembers where you went last time and
suggests the next site, because rotating helps avoid skin irritation.
Abdomen, thigh and arm, left and right
Optional side-effect tags: nausea, fatigue, headache, constipation and more
Everything flows into your doctor summary
Progress
See what's working, and what to try next
The scale only tells you part of the story. Islet connects it with how you move, eat and sleep.
Premium
Insights that tell you what to do
Islet looks at how your steps, protein and sleep line up with the scale and turns it into a
suggestion you can act on in one tap.
"You've averaged 7.7k steps a day. Update your activity level to Moderate?"
This week at a glance: weight change, average steps, protein days hit
Insights for foods and activity, too
A weight trend, not a daily verdict
Log your weight in a tap, or let it come in from Apple Health. Islet shows the trend, so one
salty dinner doesn't feel like a setback.
Full weight history and trend line

Plan ahead
Meals and movement, planned for you
Decide once for the week, then just follow along.
