EON keeps every subscription in one place, so you're never blindsided by a trial you forgot to cancel, a membership that quietly raised its price, or a charge you don't recognize. SEE YOUR SPENDING AT A GLANCE The home screen shows exactly what you'll spend this month, quarter, and year. Monthly average and lifetime total, all upfront. REMINDERS BEFORE EVERY CHARGE Set a custom lead time for each subscription. Get notified before a free trial ends or an annual plan renews — you stay in control. MULTI-CURRENCY WITH DAILY RATES USD, JPY, EUR and more are converted to your home currency automatically, with exchange rates refreshed daily. BILLING CALENDAR See which charge lands on which day across the month, each marked with its subscription icon. BEAUTIFUL SUBSCRIPTION CARDS Auto-fetch official app icons by searching the App Store, or pick your own from Photos. Cards tint to each icon's color. HOME & LOCK SCREEN WIDGETS Check your next charge and monthly total without opening the app. ICLOUD SYNC Your data syncs across devices through your own iCloud — no account required. PRIVACY FIRST No account, no servers, no tracking. Your data lives only on your device and in your own iCloud. The developer never sees it. EON is completely free with no paywall. If it saves you a few bucks, you're welcome to buy the developer a coffee — entirely optional, unlocks nothing.
