Frequently asked questions
BurnCurve is a focused measurement tool. These answers explain what it does, what it needs, and what stays under your control.
What is adaptive TDEE?
Total Daily Energy Expenditure is the energy you burn in a day. BurnCurve starts with a standard formula estimate, then compares recent intake with weight change to infer an adaptive TDEE. The range stays visible because the result is still an estimate.
How long does BurnCurve take to learn?
You can use the formula target immediately. The band may begin narrowing after about a week of useful logs. Several weeks of recent weight and intake history usually produce a stronger measurement. Gaps are allowed, but more consistent inputs make the estimate more useful.
What does BurnCurve read from Apple Health?
With your permission, BurnCurve can read weight, dietary energy, body fat, active energy, resting energy, and step count. Health access is optional and read-only. BurnCurve cannot add, change, or delete Health samples.
Does Apple Health determine my adaptive TDEE?
No. BurnCurve can show completed-day active plus resting energy from Apple Health as a separate iPhone estimate. That comparison never changes the adaptive result learned from intake and weight change.
Where is my data stored?
Weight, intake, body fat, goals, and guidance are stored only on your iPhone. BurnCurve has no account or cloud sync. Mythgate does not receive those records.
Does BurnCurve include a free plan?
No. BurnCurve is the complete product, not a limited free tier. BurnCurve Plus keeps access to history, Health features, guidance, and the rest of the app.
Which plans include a trial?
Monthly at $6.99 and Annual at $39.99 may include 14 days free for eligible new subscribers. Weekly at $2.99 has no trial and bills after Apple confirms the purchase. The App Store purchase sheet shows your actual local price and eligibility before you subscribe.
How do I cancel a subscription?
Open iPhone Settings, select your Apple Account, choose Subscriptions, then select BurnCurve. Cancellation stops the next renewal. Access continues through the end of the current paid period.
How do I restore BurnCurve Plus?
Open BurnCurve Settings and select Restore Purchases. Use the same Apple Account that made the purchase. If access does not return, confirm the subscription is active in Apple Subscriptions, then contact support.
How do I delete my data?
Choose Delete App, not Offload App, in iPhone Settings to remove BurnCurve and its local data. Samples already in Apple Health remain under your control in the Health app. Subscription records remain with Apple and RevenueCat as required to manage purchases.
Why is my estimate still a guess?
Adaptive TDEE needs enough recent weight and intake history to compare energy eaten with weight change. Keep weighing in and make sure dietary energy is available for enough recent days. A typed weigh-in can be used even when Health is unavailable.
Why is Health data missing?
Open BurnCurve Settings and check the Health connection. In the Health app, confirm BurnCurve can read the relevant data type and that another app or device actually wrote samples. Some food loggers do not write dietary energy to Apple Health.
Need health or medical guidance?
BurnCurve is for general wellness and cannot evaluate whether a calorie target is appropriate for a medical condition. Contact a qualified health professional for personal medical advice.
