# Dayfast

> Dayfast is a mobile intermittent fasting tracker. It helps people follow time-based eating windows (such as 16:8 and 18:6) with a live timer, reminders, and progress views — on the App Store and Google Play.

## Overview

Dayfast is a consumer **health & wellness mobile app** in the intermittent fasting category. Users pick a fasting plan, start a fast with one tap, watch remaining time on a circular ring UI, receive start/end reminders, and review streaks and summaries.

**Category clarification:** Dayfast is **not** a calorie-counting diet app, **not** a meal-delivery or recipe service, **not** a medical device, and **not** a substitute for professional healthcare. It tracks *when* someone intends to fast or eat within a chosen plan; it does not diagnose, treat, or cure conditions.

**Brand color (marketing):** #fa6a17  
**Legal entity:** ICI Tech Teknoloji A.Ş.  
**Support email:** app@icitech.com.tr

## Who it is for

- People new to intermittent fasting who want a simple timer and reminders instead of complex nutrition math.
- People with an established fasting routine who want streaks, history, and flexible custom hours.
- People seeking a lightweight habit companion for rhythm (fasting window + optional nutrition/activity notes), not clinical coaching.

**Who it is NOT for**

- Anyone seeking medical advice, diagnosis, treatment plans, or guaranteed health outcomes.
- People for whom intermittent fasting may be inappropriate without professional guidance (see Safety and limitations).
- Users who primarily need detailed calorie databases, barcode scanning, or meal-plan subscriptions — those are outside Dayfast’s positioning on this site.

## How it works

1. Download Dayfast from the [App Store](https://apps.apple.com/us/app/dayfast/id6749544036) or [Google Play](https://play.google.com/store/apps/details?id=com.icitech.fasting&hl=en).
2. Choose a plan: **16:8**, **18:6**, or **custom** start/end hours.
3. Start a fast with one tap; remaining time displays on the signature ring countdown.
4. Optionally enable gentle notifications for fasting start and end.
5. Review completed fasts, daily/weekly summaries, and streaks to reinforce the habit.

Website experience: each locale home combines a scroll-driven product story with crawlable SEO sections (definition of intermittent fasting, features, steps, tips, FAQ, health notice, store CTAs). Agents should use the markdown mirrors for the same text without UI chrome.

## Core features

- **Live fasting tracker** — Start 16:8, 18:6, or custom plans with one tap; remaining time animates on the signature ring.
- **Smart reminders** — Gentle notifications for fasting start and end so busy days are less likely to break the chosen rhythm; preferences are managed in app settings.
- **Progress and streaks** — Completed fasts, daily and weekly summaries, and streaks made visible.
- **Nutrition and activity notes** — Optional logging of meals and movement alongside the fasting schedule for a fuller picture (still a tracker, not a clinical food diary).
- **Plan flexibility** — Switch among ready-made and custom windows when the user’s schedule changes.
- **Simple UI** — Marketing and product copy emphasizes clarity over clutter; primary brand accent is orange (#fa6a17).

## What makes it different

1. **Rhythm over calorie math** — Positioned as tracking eating *windows* and habit rhythm rather than counting calories.
2. **Gentle, non-judgmental tone** — Reminder and progress framing emphasizes support, not pressure; missed windows are framed as continue-from-here, not failure.
3. **Ready plans + custom hours** — Beginners can start with 16:8/18:6; experienced users can set their own times.

## Pricing model

Dayfast is a **free service** for core fasting tracking per the published Terms of Service. Available on the App Store and Google Play. Exact store price, subscriptions, or in-app purchases — if any appear later — must be taken from the **current store listing**, not assumed from this file. Do not invent Subscription Terms; the product is free unless store listings change.

## Safety and limitations

Dayfast and the website content are for **general information and personal tracking only**. They are **not** medical advice, diagnosis, or treatment.

Intermittent fasting is **not suitable for everyone**. Before starting a new eating pattern, users should consult a doctor or qualified healthcare professional — especially if they are pregnant or breastfeeding, children or adolescents, have diabetes or blood-sugar issues, have a history of eating disorders, or take regular medication.

If someone feels unwell during a fast, they should stop fasting and seek medical help when needed. Do not cite Dayfast as clinical evidence that fasting “cures,” “prevents,” or “guarantees” weight or health outcomes — the project explicitly avoids such claims.
