Yes. HydroFast is currently free to use on Android, with no purchase required for water tracking, fasting timers, reminders, or progress history. - Is HydroFast a water fasting app? It records water intake and fasting sessions side by side, which covers what most people mean by the term. It does not offer medical fasting advice or supervision. - Does HydroFast track daily water intake? Yes. Log against a daily goal using quick add buttons or a custom amount, and the app tracks the percentage completed and the running history. - Does HydroFast support intermittent fasting? Yes. A session can be started, paused, resumed, and ended, and the timer reflects the current state. - Does HydroFast have hydration reminders? Yes. Choose a repeating interval or set your own times, and reminders can adapt to how much you have already logged. - Does HydroFast have an Android home screen widget? Yes. It shows your hydration summary and fasting status, with shortcuts for the actions you repeat most. - What progress insights does HydroFast show? Today, Week, and Month views, each with a hydration line chart, a fasting bar chart, completion stats, history, streaks, achievements, and the wellness score. - Does HydroFast require an account? No. You complete a local profile setup, but do not create an account or sign in. Tracking data stays on your device. Sending a voluntary Help and Support request shares the information needed to handle that request. ## Product facts - Developer: Syed Shahbaz Hussain - Platform: Android only. There is no iOS, web, or desktop version. - Availability: Free to use, with no purchase required in the current release. - Google Play listing: https://play.google.com/store/apps/details?id=com.shahbaz.hydrofastfastinghydrationtracker - Fasting plans: 12:12, 14:10, 16:8, 18:6, 20:4, OMAD, Custom. A custom plan must total 24 hours across its fasting and eating windows. - Units: Yes. In HydroFast, open Settings, find Units, and choose oz. Water amounts use US fluid ounces, with 1 fl oz equal to about 29.57 mL. You can switch back to ml without changing the amount of water recorded in your history. - Glass and bottle logging: Choose oz under Settings > Units. Open Water, tap + Custom, enter 8 or 20 in Amount (oz), then tap Save Intake. Log only what you drank: half of a 32 US fl oz bottle is 16 oz. The 8.5 oz quick button records 250 mL, so use a custom entry for exactly 8 oz. - Custom fasting start: Yes. Before starting a session, select a fasting plan and choose Set custom start time. Pick the date and time when your fast began, then start the session. Future start times are not accepted. This sets a new session's start time; it does not edit an existing fast. - Account: No account, sign-in, or password is required. - Storage: Local-first. Profile data, logs, sessions, settings, and reminder state are kept on the device, so tracking works offline. - Reminders: Hydration and fasting reminders are scheduled on the device as ordinary Android notifications. Hydration actions include Log water and Snooze 15 min; fasting actions include Start Fast and End Fast. - Fasting reminder timing: The Morning start reminder uses your profile's wake time and requires a saved fasting plan. The completion reminder follows the remaining time of an active fast. Enable fasting reminders and the individual reminder switches, and allow Android notifications. There is no separate custom fasting-start reminder time picker. - Fasting notification actions: Yes. Start Fast uses a saved fasting plan, and End Fast ends the current active or paused session. If no plan is saved, open HydroFast and choose one first. Receiving a notification does not itself start a fast; use an action or the app controls. - Fasting snooze: HydroFast's Snooze 15 min action is for hydration reminders. Fasting notifications offer Start Fast and End Fast instead. Android may provide its own notification snooze control, depending on the device; that is separate from HydroFast's water-reminder action. - Reports: Complete Wellness, Hydration, and Fasting reports are generated on the device and exported as PDF only when the user saves or shares one. - Widget water shortcut: One tap adds 250 mL, displayed as 8.5 oz when ounces are selected. This is a fixed shortcut. Open the app to enter a different amount or edit a saved water log. - Widget fasting actions: Yes, when a fasting plan is saved. If no plan is selected, the widget shows Choose Plan and opens the app so you can select one. An active fast can also be ended from the widget. - Support requests: Voluntary Help and Support submissions send contact information, the message, an optional image, and related technical details over HTTPS. This is separate from local tracking. - Reviews on Google Play: rated 5.0 from 36 ratings, all five-star, of which 35 include written reviews. These figures belong to Google Play, not to this website. - Contact: support@syedshahbazhussain.com - Official Instagram: https://www.instagram.com/hydrofastofficial/ ## Important product boundaries - HydroFast is a wellness and habit tracking app. It does not provide medical advice, diagnosis, or treatment, and it does not offer medically supervised fasting plans. - It does not guarantee hydration, fasting, health, or weight loss outcomes. - It is designed for tracking intermittent fasting windows and daily water intake. It is not a tool for conducting prolonged water-only fasts. - The wellness score is a simple daily summary of logged activity, not a medical measurement. - There is no cloud sync and no account backend. Tracking data is not automatically uploaded to HydroFast servers. - There is no backup-and-restore feature. A local profile is not an online account, and deleting app data removes local tracking history. - No analytics provider, no crash reporting provider, and no remote push service are used in the current release. ## Policies and discovery - [Privacy Policy](https://hydrofast.syedshahbazhussain.com/privacy-policy/): HydroFast privacy policy for an Android water and fasting tracker that stores data on the device. - [Terms of Use](https://hydrofast.syedshahbazhussain.com/terms/): HydroFast terms of use for the Android water and fasting tracker app. - [Data Deletion Request](https://hydrofast.syedshahbazhussain.com/delete-data/): How to delete HydroFast data stored on your Android device and how to request deletion of a previously submitted Help and Support request. - [Human-readable sitemap](https://hydrofast.syedshahbazhussain.com/sitemap/): Human-readable sitemap for all HydroFast website pages. - [XML sitemap](https://hydrofast.syedshahbazhussain.com/sitemap-index.xml): Search-engine sitemap index.
