INTERMITTENT FASTING AS A SIMPLE STEP TOWARD BALANCE Intermittent fasting is a modern approach to nutrition that helps bring structure to your day, better understand your bodyβs signals, and build healthy habits without strict restrictions. Fastia is a fasting tracker that makes fasting clear, convenient, and accessible for everyone. Instead of complicated diets and constant calorie counting, you get a simple system: a clear schedule of when to eat and when to pause. This approach helps maintain balance in your diet and creates a sense of control in everyday life. HOW TO START FASTING WITHOUT STRESS Starting intermittent fasting is often difficult due to a lack of structure. Fastia helps make this process easy and natural, even if youβre just getting familiar with fasting. The app offers popular routines that easily fit into your lifestyle: 16:8 β a convenient daily format for beginners, 18:6 β a more focused eating schedule, OMAD β a format for those seeking clear discipline. You can choose the option that suits you best and adjust it at any time. A FASTING TRACKER THAT SIMPLIFIES LIFE Fastia works as a smart fasting timer that helps you stop worrying about time and stay on track. You start a session β and the app guides you throughout the entire period. Gentle reminders let you know when your fasting window begins and ends, while statistics allow you to track your progress. This creates a sense of stability and helps build consistency without unnecessary pressure. Over time, managing your eating becomes a habit rather than a task. A FLEXIBLE EATING SCHEDULE THAT FITS YOUR RHYTHM Every day is different, so itβs important to have a tool that adapts to you. Fastia allows you to customize your fasting schedule according to your lifestyle. You decide when to start your fasting period, when your eating window opens, and which routine fits your schedule. HEALTHY HABITS WITHOUT PRESSURE Building a healthy lifestyle starts with small steps. Fastia helps make these steps consistent and easy to follow. When you see your progress and stability, internal motivation naturally grows. WHY FASTIA BECOMES PART OF YOUR DAILY ROUTINE Fastia is designed to simplify the process and make it comfortable: a simple and intuitive fasting timer, clear statistics and progress tracking, reminders that help you stay consistent, support for popular routines like 16:8, 18:6, OMAD, and a focus on building habits and discipline. Itβs a tool that helps you move forward without overwhelm. FEEL CONTROL AND BALANCE Intermittent fasting is about balance between meals and periods of rest for your body. Fastia helps make this balance clear and easy to maintain in everyday life. Instead of chaotic eating β a clear structure. Instead of complex rules β simple solutions. Instead of pressure β gradual progress. Fastia is your daily assistant in building healthy habits and managing your nutrition.

Fasting Clock
Read full descriptionHide full description
Start a fasting timer, close the app, and trust the number when you come back. FastTrkr tracks your intermittent fasting window β 16:8, 14:10, 12:12, 18:6, 20:4 or OMAD β shows elapsed time against your target, then counts down the eating window that follows. Most fasting apps want your email, your weight, your meal photos and a coaching plan. FastTrkr is the opposite: a precise fasting clock with an honest log. The timer is anchored to your iPhone's continuous system clock, so elapsed time stays correct through reboots, timezone changes and clock adjustments. And it records the hours that actually ran β end at 15.2 hours and the log says 15.2, never a rounded-up target. WHAT YOU GET β’ Open the app 14 hours into a 16:8 and "14:22:07 of 16h" is already on the ring β the clock kept counting while the app was closed β’ End the fast and an eating-window countdown takes its place, so you know dinner has to land inside the next 7 hours 40 minutes β’ One local reminder fires the minute your window completes β no fast quietly stretching to 19 hours because you forgot it was running β’ A day streak, windows-met total and lifetime fast count sit under the ring every time you open the app β’ Tapped End by accident at hour 3? Edit the start and end times and the session is corrected, with a note field for how it felt β’ A 14-day bar chart shows your recorded fasting hours at a glance PERFECT FOR β’ 16:8 beginners who want one number, not a lifestyle program β’ OMAD and 20:4 practitioners who need a timer that takes long windows seriously β’ Anyone who quit a fasting app because it demanded an account and a weigh-in first β’ Shift workers whose windows move β custom hour targets when the standard presets don't fit WHY NOT JUST USE THE CLOCK APP? A plain timer forgets everything when it ends, loses your fast when the phone reboots, and knows nothing about eating windows. FastTrkr survives a reboot mid-fast, logs every session to an editable history, keeps your streak, and tells you when the eating window closes β things a stopwatch will never do. PRIVATE BY DEFAULT No account, no analytics, no ads, no server. Every session is stored on your iPhone and the app works fully offline. Nothing you record ever leaves the device. FastTrkr is a timer, not medical advice. Fasting is not suitable for everyone β read the in-app safety guidance and talk to a clinician if you are unsure. FULL ACCESS FastTrkr Pro unlocks the extended protocols β 18:6, 20:4, OMAD and custom targets up to 23 hours β plus the 14-day hours chart. Choose a weekly or yearly subscription, or a one-time lifetime purchase. Start your first 16:8 tonight β by breakfast the ring will tell you exactly where you stand.
