Measuring
How do I measure each site?
Use a soft, non-stretch tape, snug on the skin without pressing in, and read it at the end of a normal breath out. Leano lights up each site on the twin while you measure. The short version:
| Site | Where the tape goes |
|---|---|
| Neck | Just below the Adam’s apple, sloping slightly down toward the front |
| Shoulders | Around the widest point of both shoulders, arms at your sides |
| Chest | Across the fullest part of the chest, under the armpits |
| Upper arms | Halfway between shoulder and elbow, arm relaxed |
| Forearms | Around the widest part, just below the elbow |
| Waist | Midway between your lowest rib and the top of your hip bone |
| Belly | Level with your navel |
| Hips | Around the widest part of your buttocks |
| Thighs | Just below the fold of the buttock, around the thickest part |
| Calves | Around the widest part of the calf |
The measuring guide has a picture and the details for every site.
Which routine should I pick?
Quick covers waist, hips and chest in about two minutes. Standard adds the belly and both upper arms and thighs, eight parts in all. Full body measures all 14 parts on both sides. My selection measures the parts you pick. You can switch routines before any session.
What does two readings do?
With two readings on (Settings, Measuring), you measure each part twice and Leano keeps the average. If the two readings are far apart, it tells you so you can measure once more.
Can I add a session from an earlier date?
Yes. Before you save a session, set its date and time on the review step. A session cannot be dated in the future.
Can I measure places that are not on the list?
Pro lets you add your own parts, such as the wrist, and set a target for any part. Parts you created in Leano 1 or brought in with a CSV import stay usable without Pro.
Units
Can I use inches, pounds or stones?
Yes. In Settings, Units, set the tape to centimetres or inches and weight to kilograms, pounds or stones. Height follows the tape unit, in centimetres or feet and inches. Leano stores every value in metric and converts it for display, so switching units never changes your history.
Weight trend
How does the weight trend work?
Each day moves the trend 10% of the way toward that day’s weight, so the water and salt swings of single mornings barely move it. After days without a weigh-in, the next one counts once for every day since the last. The weekly rate is the slope of the trend over the last three weeks, and it shows once your weigh-ins cover a week.
What does the goal weight show?
How far the trend still has to go, and the next milestone on the way (every 2 kg, 5 lb or half a stone). Pro adds an estimated goal date from the last three weeks and the history of milestones you reached. Leano gives no date while the data is thin, the trend is level or moving away from the goal, or the date would be more than two years off.
Can Leano read my weight from a smart scale?
If your scale saves to Apple Health, connect Apple Health in Leano’s Settings. Leano reads your weight entries up to a year back, then new ones each time you open the app. On a day with both your own entry and a Health entry, your own entry wins.
Pro and purchases
What does Pro add?
The heat map and time-lapse, any two dates side by side for the body and for photos, charts for every part, the estimated goal date, milestone history and weight charts beyond 90 days with the waist on the same chart, the PDF report, and your own parts with a target for each part.
How do I restore a purchase?
Open Settings in Leano and tap Restore purchases while signed in to the App Store with the Apple Account you bought Pro with. An active Leano 1 subscription is recognised the same way.
How do I cancel a subscription?
Tap Manage subscription in Leano’s Settings, or open Settings on your iPhone, tap your name, then Subscriptions. Cancel at least 24 hours before the end of the current period to avoid the next charge. Pro stays on until that period ends.
Can I get a refund?
Apple handles payments and refunds. Request one at reportaproblem.apple.com.
What happens to my data when Pro ends?
Nothing is locked. Every session, photo, weigh-in and value stays visible, editable and exportable. The Pro views close until you subscribe again.
Export and import
How do I export my data?
In Settings, tap Export CSV. The file has one row per value with the columns date, time, part, part_name, value, unit and note, in the units you chose, and it includes your weigh-ins. Export is free.
What is in the PDF report?
The PDF report (Pro) lists your sessions, the four ratios and estimates, and how each part changed. Share it or save it to Files.
How do I import a CSV file?
In Settings, tap Import CSV, then choose a file or paste its text. Leano reads its own exports, Leano 1 exports and any sheet with date, part, value and unit columns. Dates like 2026-10-16 or 16.10.2026 work, a time column is optional, and commas, semicolons or tabs can separate the columns. Part names can be in any of Leano’s 12 languages. You see a summary before anything is saved, and values already in Leano are skipped.
Moving from Leano 1
Will my Leano 1 data move over?
Yes, on its own. Update the app and open it. Leano 2 brings over your measurements, weight entries, goals, life events, your own parts, units, height and reminder, plus the progress photos still on the device. It then shows how many sessions and photos moved, and how many photos were no longer on the device.
Do I need to buy Pro again?
No. An active Leano 1 subscription is recognised through the App Store. If Pro does not show after a minute, tap Restore purchases in Settings.
Apple Health
What does Leano read and write?
Leano reads your weight entries (up to a year back, then new ones) and your latest height and body fat. With Save measurements to Health turned on, it writes your waist, weight and body fat after each session, and each weigh-in you log. Health data stays on your device.
How do I change Leano’s access to Health?
Open the Health app, tap your profile picture, then Apps under Privacy, then Leano. You can also go to iOS Settings, Privacy & Security, Health, Leano.
Why is Apple Health missing on my iPad?
Apple Health on iPad needs iPadOS 17 or later. On older versions Leano hides the Health settings.
Weekly reminder
How does the reminder work?
Turn on Weekly reminder in Settings and pick a day and time. It is a local notification scheduled on your device. If it does not appear, allow notifications for Leano in iOS Settings, Notifications.
Your data
Where is my data stored?
On your iPhone or iPad. Leano has no account and no server for your data. The privacy policy lists what connects to the internet: App Store purchases and the app’s update check.
How do I delete everything?
In Settings, Your data, tap Erase all data. Sessions, photos and settings are removed from the device; purchases stay with your Apple Account. Deleting the app removes everything Leano stored. Values Leano saved to Apple Health stay in Health until you delete them there, and files you exported stay where you saved them.
