Kairox Kairox is a screen time and digital wellness app designed to help you break doomscrolling habits by making distracting apps something you unlock, not something you open automatically. Choose the apps that waste the most time, complete exercises like push-ups, squats, or lunges, and earn a limited amount of access. Kairox helps you interrupt mindless scrolling, move more throughout the day, and use social media more intentionally. Kairox requires an active subscription to access and use the app. There is no free version or permanently free content. SUBSCRIPTIONS Kairox offers the following subscription options: Monthly Subscription Provides full access to all Kairox features with a recurring monthly subscription. Yearly Subscription Provides full access to all Kairox features with a yearly subscription and includes a 3-day free trial. If you do not cancel before the trial ends, the full yearly subscription price will be charged automatically. FEATURES INCLUDED WITH ALL SUBSCRIPTIONS BLOCK DISTRACTING APPS Select the social media and entertainment apps that distract you most. Kairox uses Apple’s Screen Time and Family Controls features to restrict access to the apps you choose. MOVE TO UNLOCK Complete push-ups, squats, or lunges to regain access to selected apps. Instead of receiving unlimited access, you unlock a specific amount of time before the restriction returns. CAMERA-BASED REP COUNTING Use your device’s camera during an active movement session so Kairox can recognize supported exercises and count completed repetitions. CUSTOM EARNING RULES Choose your exercise, set the number of required repetitions, and decide how much app access each completed session earns. BUILD STREAKS AND TRACK PROGRESS Stay consistent with streaks, milestones, exercise history, unlock history, and progress tracking. SCREEN TIME INSIGHTS Review your app usage, completed movement sessions, unlocked time, and long-term progress to better understand your habits. REMINDERS AND NOTIFICATIONS Receive exercise reminders, unlock alerts, streak updates, and notifications when your earned access is about to end. PERSONALIZED APP CONTROLS Choose which apps are restricted and adjust your movement, access, and notification preferences at any time. HOW IT WORKS Choose the apps you want Kairox to restrict. Select push-ups, squats, or lunges. Complete the required number of repetitions. Unlock a set amount of app access. When the earned time expires, the selected apps are restricted again. Complete another movement session whenever you want to regain access. PURCHASE DETAILS Payment is charged to your Apple ID at confirmation of purchase.

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.

Verdict
The clearest difference is update cadence: Kairox at every 4 days against Chronaya's every 2 weeks. Chronaya's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads and in-app purchases there is nothing between them.
