Catch return windows, warranty expirations, free trials and subscription renewals before they cost you. Chronaya keeps each important date together with its reminders, receipt, notes and next step, on your device and without an account. A calendar can remind you of a date. Chronaya also keeps what you need to act on it: the receipt for a return, the invoice for a warranty claim, the price of a renewal, or the link to manage a free trial. WHAT YOU CAN TRACK • Return windows: the last day to return an online or in-store purchase • Warranties: the warranty expiration date, with the receipt or invoice • Subscriptions and free trials: a reminder before a renewal or before a trial turns into a charge • Memberships and recurring payments: weekly, monthly or yearly • Documents: passport, ID card, driver's license, visa and permit expiry dates • Insurance: car, home, health and travel policy renewals • Vehicles: registration, inspection and insurance dates • Any other personal or household deadline REMINDERS THAT FIT THE DEADLINE • Get reminded on the day, or from 1 day up to 1 year before • Start with sensible defaults for each type, such as 7 days and 1 day before a return deadline, or 30 days and 7 days before a document expires • Choose the time of day your reminders arrive • Mark a subscription payment as completed and the record moves to the next renewal date • Reminders are scheduled on your device and work offline SEE WHAT NEEDS ATTENTION • Dates are grouped into Overdue, Today, Next 7 Days, Next 30 Days and Later • Each type of record suggests a useful next step, such as checking the saved receipt before a return • Search titles, notes and attachment names, or filter by category RECEIPTS AND DOCUMENTS IN THE SAME PLACE • Take a photo of a receipt, or add images and PDFs from your photos and files • Preview supported attachments inside the record • Save the price, store, order or serial number, and your own notes • Tap links and phone numbers saved in your notes When a reminder arrives, the date and the proof you need are already together. SEE WHAT YOU AVOIDED PAYING When you confirm that you canceled a subscription before it renewed, Chronaya adds that payment to your yearly savings summary. Only renewals you mark as canceled are counted. Chronaya never estimates savings for you. PRIVATE AND OFFLINE BY DESIGN • No account or sign-up • Records and attachments are stored on your device • No Chronaya cloud account; your records and attachments are not uploaded automatically • No ads • Back up your records and attachments to a single file and restore them later Internet access may be needed for app updates, App Store purchases and opening saved links. Reminder delivery depends on your notification settings. FREE AND LIFETIME PRO Chronaya Free includes up to 5 active records, 1 attachment per record and 2 reminders per record. Archived records do not count toward the limit. Lifetime Pro is an optional one-time in-app purchase, not a subscription. It removes these limits and lets you choose a separate reminder time for each record. Backup and restore, offline use, the savings summary and the ad-free experience are included for everyone. ALSO INCLUDED • Light and dark themes, including a true black dark mode • English and Turkish • Your choice of currency and date format Chronaya is for the dates that can cost you money, time or access when they slip by.

DunCrux is a task manager that helps you focus on what matters most. Instead of making you maintain a rigid priority list, DunCrux organizes tasks using keywords. Each keyword has an “elevation” that represents its importance. Tasks with higher-priority keywords rise toward the top automatically. -- Priorities That Adapt -- Move a task up or down to show DunCrux what matters to you. Its keyword priorities adjust over time, allowing your task list to evolve alongside your goals. -- Capture And Organize -- • Create tasks quickly • Add due dates and snooze tasks until later • Break large tasks into nested subtasks • Use @keywords in task text or add #tags • Search and filter your work • Create saved task views • Review upcoming and completed tasks -- Understand Your Workload -- Explore insights into completed tasks, open work, keyword priorities, and activity patterns. See how your workload changes and discover when you are most productive. -- Local First By Design -- DunCrux’s core task-management features work without an account. Your workspace remains available locally on your device, even when you are offline. Cloud sync is optional. Sign in when you want to keep your DunCrux workspace synchronized across supported devices. You can also export your data whenever you choose. Some advanced features require DunCrux Pro. With the free version you have unlimited tasks but are limited to 10 Keywords for tracking priorities. Additionally paying for or subscribing to DunCrux Pro unlocks saved views. Subscribing to DunCrux Pro+Synch will unlock cloud syncing across multiple devices. Spend less time deciding what to do next—and more time making meaningful progress. Terms of Service: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
