About

Shift Meal Timer

Features
Read full description

Stop eating breakfast at 4 AM because your shift ended and you have no idea what to call this meal. Shift Meal Timer gives night shift workers and 12-hour shift workers a structured four-meal schedule built around their actual hours. Every night shift worker knows the problem: your body wants food at strange times, you skip meals because you do not know if it counts as lunch or dinner, and the coffee you drank at 3 AM is still keeping you awake at 9 AM. Generic meal apps assume you wake up at 7 AM and sleep at 11 PM. You do not. HOW IT WORKS 1. Pick your shift pattern: 12hr Night, 12hr Day, 8hr Day, 8hr Evening, Rotating, or Custom. 2. Set your usual sleep time and average sleep duration. 3. Shift Meal Timer calculates four meal windows tuned to your hours: Pre-shift Main, Mid-shift Meal, Late-shift Snack, Post-shift Wind-down. A caffeine cutoff is set six hours before sleep. Set up in under a minute. No account required. No tracking. CORE FEATURES Four-Meal Schedule Each meal slot shows the time, meal type, and food suggestions. Meals falling between midnight and 6 AM are tagged Light protein-focused with a dark background so you can see at a glance which ones are night-shift meals. Caffeine Cutoff A red indicator shows the latest time you should stop caffeine before your sleep window. Protects your daytime sleep on rotating shifts. Work Day and Off Day Toggle Switch between your shift schedule and a fixed off-day schedule (7:30 AM, 12:30 PM, 6:30 PM) with one tap. Next-Up Countdown The bottom bar always shows the next upcoming meal with a live countdown so you know what to grab and when. Notifications Local push notifications fire 15 minutes before each meal. Toggle individual meals on or off. No server, no tracking. PRO FEATURES Upgrade to Pro for deeper tools: - Check-in: log whether you ate or skipped each meal - Adaptation Report: your schedule shifts based on your hunger signals and skip patterns over 30 days - History: monthly calendar view of your eating record - Custom notification timing (5 to 60 minutes before each meal) - Multiple shift presets and quick switching - Caffeine cutoff adaptation based on your sleep quality PRIVACY FIRST - No account, no login, no email required - All data stored locally on your device using Hive - No tracking, no ads, no third-party analytics - RevenueCat handles subscription transactions only; no personal data sent Shift Meal Timer provides meal-timing guidance based on your shift schedule and general nutrition principles. It is not a substitute for medical or dietary advice from a qualified clinician or registered dietitian. Adapt the suggestions to your personal needs and consult a clinician or registered dietitian for individual recommendations.
