Food

Track calories and protein.

Search for food, scan a barcode or add a meal you’ve saved before. See your daily calories and protein against your targets. Corrections to a food’s nutrition are saved for next time.

Workouts

Log weights, reps and sets.

Record your exercises and save routines to use again. When you repeat a workout, Strata fills in your previous weights and reps so you can update them.

Weight

Track your weight.

Enter your weight or import it from Apple Health. The chart shows your weigh-ins and a seven-day average, so you can follow changes over time.

What else can I track?

You can also record sleep, activity, periods, body measurements, medication, notes, bowel movements and skin changes. Custom trackers let you record things such as water, coffee or symptoms. All twelve modules are free, and you choose which ones appear in the app.

Logging works offline. Food search, Coach and other online features need a connection.

Weekly report · Premium

Review your week in one report.

With Premium, you get a report every Monday based on the records you share with AI. It summarises your week with charts and checks for patterns, such as eating more after shorter nights. Pattern analysis needs enough logged data.

How are patterns found?

Strata compares your records across days and tests whether differences could be due to chance. Each reported finding includes the number of days used and a confidence level. There may be no clear pattern, and a statistical connection does not establish a cause.

Coach

Ask questions about your records.

Coach is Strata’s AI chat. It can use the records you share to answer questions about your meals, weight and training. You get three free replies; Premium includes continued access.

You can also connect your own Claude account to read your shared records. Strata’s connection is free; Claude’s terms apply.

Is my weight still going down?
Your seven-day average is 69.2 kg, down 0.3 kg this week. Friday’s higher weigh-in hasn’t changed the overall direction.

Privacy

How Strata uses your data.

Read the privacy notice ↗

Control access to your records.

Each tracking module has an AI-sharing switch, which starts on. Turn it off in Settings to keep that module’s records out of Coach, weekly reports and connected AI apps.

Progress photos stay on your phone.

Progress photos are never uploaded. Cycle records stay on your phone unless you turn on syncing.

No ads or data sales.

Strata records how its features are used and uses de-identified data for research. The privacy notice explains what is collected, what is excluded and which uses require your permission.

Questions
When can I download Strata?

Strata is coming to the App Store for iPhone with iOS 17 or later. The download link will be on this page when it launches. Android isn’t available.

What can I use for free?

All twelve tracking modules are free, including food, weight and workouts. Food search, barcode scanning, the on-device label scanner, widgets, Siri and Apple Health support are included. You also get three Coach replies. Premium adds weekly reports, continued Coach access, meal-timing analysis and pattern insights.

Do I have to track everything?

No. Choose which modules to use and change them in Settings whenever you want. Turning one off hides its screens, cards and reminders. Its saved records are kept.

What happens if I miss a few days?

After three or more days without logging, Strata may offer an optional restart with a calorie target 150 kcal higher for seven days. You can skip it and return to normal logging.

Will every report find a pattern?

No. The report can summarise your week without finding a pattern. Its automatic pattern search needs at least 14 days of data for each measure it checks. Comparisons must also pass statistical checks, so more records do not guarantee a result.

How does Strata look for connections?

Strata compares groups of days, such as days after shorter and longer sleep, and tests the differences. It can check effects up to three days later and adjusts for testing many comparisons. AI writes the report using these results. The methods are Cliff’s delta, Mann–Whitney U and Benjamini–Hochberg correction. Results describe your records and do not prove cause and effect.

What does the AI see?

AI sharing starts on for each module you use. Turn it off in Settings to exclude that module’s records from Coach, reports and connected AI apps. Cycle records are unavailable to them unless you also turn on syncing. Strata requires its AI providers not to train on or retain these requests. If you connect your own AI account, that provider’s terms apply.

What works offline?

You can log entries, record workouts and use the on-device label scanner offline. Food search, AI label reading, Coach and downloading new reports need a connection. Reports already downloaded remain readable offline.

Is Strata a medical service?

No. Strata helps you record your routine and explore patterns. It doesn’t diagnose conditions. AI answers can be wrong, and cycle estimates are not intended for contraception or fertility planning.

Coming soon to iPhone.

For iPhone with iOS 17 or later. All twelve tracking modules are free. Reports and continued Coach access require Premium. The download link will be here when Strata launches.
