Emvron is the shift worker's best friend — a smart work schedule and income tracker that puts your paycheck front and center. CORE FEATURES ● Smart Alarm Sync Set your schedule once. Emvron automatically creates system alarms in your iPhone's Clock app — and updates them whenever your schedule changes. No more manually setting alarms for each shift. The Fail-Safe Scan runs every time you open the app, verifying that every alarm matches your current schedule. 100% alarm reliability — even after reboots or last-minute schedule changes. ● Real-Time Income Gauge Clock in and watch your earnings tick up in real time, every second. See exactly how much you've earned since your shift started. Income first. Schedule second. ● Two Scheduling Modes Pattern Mode — for rotating shift workers. Define your repeating cycle (e.g., Day → Evening → Night → Off) and Emvron fills your entire year automatically. Flexible Mode — for part-timers and irregular schedules. Enter shifts day-by-day, or set recurring weekly shifts for each job. ● Income Breakdown View your monthly earnings at a glance — total hours, overtime pay, night premium, and estimated net pay, all in one place. ● Clock In / Clock Out Tap to clock in. Tap to clock out. Emvron records your actual hours and updates your income calculation instantly. ● Overnight Shift Support Emvron handles date-boundary crossings correctly. Night shifts that span midnight are tracked, paid, and alarmed based on the shift start date — no manual correction needed. ● Multiple Jobs — Pro Working two jobs? Each job gets its own color, hourly rate, and schedule. Emvron tracks them separately and shows your combined monthly income at a glance. ● Income Simulator Before you accept that extra shift, know exactly what you'll earn. Simulate any shift — including night premiums and overtime — and see the payout instantly. ● Income History — Pro See your earnings trend beyond the current month — review past months at a glance. ● Payslip Check — Pro Compare your payslip's reported pay against what Emvron tracked for that month, and catch discrepancies before they slip by. ● iCloud Sync — Pro Your schedule and income data stay in sync across all your Apple devices automatically. ● Live Activities Clock in and your earnings show up right on your Lock Screen and Dynamic Island — no need to open the app to check how much you're making. ● Home Screen Widget — Pro See this month's earnings and your next shift right from your Home Screen. WHY EMVRON Most schedule apps are just calendars. Emvron is an income engine — built for the people who work nights, rotate shifts, and deserve to know exactly what they've earned.
