About

Halera

Features
Read full description

Halera is a health tracker that keeps one simple daily log instead of scattering your data across five different apps. FOOD & NUTRITION Log meals and drinks by searching the USDA food database, snapping a quick photo for an AI-powered estimate, or typing a plain description like "grande latte" or "2 eggs and toast." Track calories, protein, carbs, fat, fiber, sugar, sodium, and fluids โ€” all in one entry. INTERMITTENT FASTING Start a fast with 16:8, 18:6, 20:4, OMAD, or a fully custom window. A live timer keeps you on track, and your history builds into streaks you can look back on. WEIGHT, BLOOD PRESSURE & MORE Log weight in pounds or kilograms and watch your trend line move toward your goal. Track blood pressure, sleep hours, mood, caffeine, alcohol, and symptoms โ€” turn on only the trackers that matter to you. HYDRATION & ELECTROLYTES Set daily protein and fluid goals and close the rings, with electrolyte tracking built in. YOUR DATA, YOUR CALL Export your log as a spreadsheet anytime and paste it into any AI chat for deeper analysis. Delete your account and all your data whenever you want. HALERA PLUS Every core feature โ€” unlimited manual and USDA food logging, fasting, weight, blood pressure, and every other tracker โ€” is free, forever. Halera Plus ($4.99/month or $29.99/year) adds unlimited AI-powered photo food estimates, beyond the 8 free photo estimates included every month. PRIVACY BY DESIGN Halera never sells your data or shows ads. Your health information is stored securely and used only to power your own tracking โ€” never for advertising, and never shared with data brokers. Full privacy policy at gethalera.com/privacy.html. WHY HALERA PLUS COSTS WHAT IT DOES Everything you need to track is free forever โ€” food, macros, weight, blood pressure, fasting, supplements, vitamins, barcode scanning and CSV export. No trial timer, no locked dashboard. Plus ($4.99/month, or $29.99/year โ€” just under $2.50 a month) pays for the AI photo estimates, which cost us real money on every photo. Halera runs no ads and sells no data, so subscriptions are the only thing funding it. SUBSCRIPTION TERMS Halera Plus is an auto-renewing subscription: $4.99 per month, or $29.99 per year. Payment is charged to your Apple Account at confirmation of purchase. It renews automatically unless cancelled at least 24 hours before the end of the current period, and you can manage or cancel it in your Apple Account settings at any time.
