How accurate is the weight forecast on iOS?

LyteFast uses your recent weights and calorie balance to produce a short-term weight forecast. It is designed to show realistic trends, not day-by-day guarantees, so you can see whether your current habits are moving you toward your goal.

Do I need to weigh in every day for the forecast to work?

Daily or near-daily weigh‑ins give the forecast more data and smoother trends, but LyteFast can still project a trajectory from a few weigh‑ins per week combined with your calorie deficit.

How is my weight and food data protected?

LyteFast is built as a privacy‑first iOS app: your weight, food, and fasting data are used to compute trends and forecasts, not to build advertising profiles. See the in‑app privacy policy for full details.

Weight forecast on iOS: frequently asked questions

Answers to common questions about the iOS app, weight forecast, and how LyteFast uses your data.

How does the iOS app calculate the weight forecast? ⌄

LyteFast combines your recent weigh‑ins, calorie balance, and trend direction to create a short‑range forecast. It is intentionally conservative and focuses on the near term, so you can connect daily decisions with visible changes on the chart.

Can I use the weight forecast without counting every calorie? ⌄

Yes—more detailed logging improves the forecast, but you can still benefit from daily weigh‑ins, rough calorie estimates, or fasting windows. The app is built to support different levels of precision without demanding perfection.

Is the iOS app available in my language? ⌄

LyteFast supports over 82 languages for the iOS experience, including regional variants. If your system language is supported, the app interface and educational content will appear in that language automatically.
