Plan
Plan the week. The shopping list writes itself.
Choose a recipe for each meal of the week, and Surplus adds up every ingredient into one list. Two recipes that both use chicken give you one line with the total.
For people who find it hard to eat enough
Plan your week, get nudged when it’s time to eat, and watch the weight go on.
Every feature free for 14 days · Made for iPhone
Most food apps are made for eating less. Surplus is made for eating more, calmly, one meal at a time.
That’s common, and mostly habit. Surplus helps you get a first meal in anyway, and starting small counts.
Your stomach level shows when there should be room again, and a shake can still go down before a full meal can.
Give each meal a time, and Surplus nudges you when it’s due, with an easier option if a full meal is too much.

Nudges
Give each meal a time on your day’s timetable, and Surplus reminds you when it’s due. Can’t face it yet? “Can’t eat right now” on your lock screen asks again 45 minutes later.
Logging
Your regulars, your recipes, a food search or a barcode. About 10,500 everyday foods are built in and work offline, with your own country’s foods first.
The weight gain zone
Your calories, protein, carbs and fat fill up as you go. A gold band on the calorie ring marks the weight gain zone: past the calories you need to stay the same weight, up to your target.
Your stomach level
Surplus estimates how full you’re likely to feel from what you’ve logged, and shows when you should have space for your next meal, so it comes when you can face it.
An estimate to help you time meals, not a measurement of your body.
Progress
Track your weight on a chart, add a progress photo to any weigh-in, and see your steps from Apple Health. If your weight stays flat for three weeks, your calorie target goes up by itself.
Surplus Premium

Yes. Everything you log is saved on your phone straight away, and about 10,500 everyday foods are built in. Searching the full food database and scanning a new barcode need a connection.
You get every feature for 14 days. After that, a monthly or yearly subscription keeps it going, and you can cancel any time in your iPhone’s settings. Nothing you’ve logged is lost if you stop.
No. Surplus gives general guidance and estimates. If you have a medical condition, are pregnant, or have a history of eating disorders, talk to a doctor or dietitian before changing how you eat.
