Second vs Nestkeep

Precise server time, at a glance. Second-Sync is a time synchronization tool for moments where one second matters, such as course registration and ticketing. It multi-samples the HTTP Date of your chosen site and aligns the difference from the server clock down to milliseconds. Drift tracking maintains accuracy over time, while the PiP timer lets you watch live server time even when using other apps. Key features - Precise synchronization: collects HTTP Date in parallel at least 30 times, then calculates the offset after RTT compensation, outlier removal, and EMA smoothing. - Drift estimation: runs linear regression on measured samples to track the slope of the device clock and maintain accuracy as time passes. - PiP timer: opens a Picture in Picture timer as a companion app, so you can monitor the server clock live while using a browser or other apps. - Example site shortcuts: quick buttons to load course registration pages for major Korean universities and ticket booking sites. - Multilingual support: supports Korean, English, Japanese, and Simplified Chinese, with a separate in-app language setting. Recommended for - Anyone who wants exact server time in situations where it is critical, such as registration, ticketing, or reservations. - Anyone who wants to keep accurate server time visible on iPhone or iPad while booking on the go. Notes - Synchronization may fail on sites that do not support the HTTP Date header. If so, enter another target server or use the example sites in the app. - Picture in Picture works only on supported devices running iOS 15 or later, including iPadOS. - Sync your server time with Second-Sync now. One button gives you stable synchronization and a PiP timer, so you do not miss the important moment!

Nestkeep is the simple memory for your home. It does two things, and does them well: it reminds you about the things a home needs before they slip your mind, and it keeps your receipts, warranties and manuals in one safe place. No setup, no accounts, no clutter. Add something only when you want to. REMINDERS - Add anything a home needs on a repeat: water filter changes, smoke alarm batteries, gutter cleaning, insurance renewals, servicing. - Choose how often in days, weeks, months or years. It starts today and repeats until you delete it. - See at a glance what is due, due soon, or overdue. - Swipe to mark done or snooze a week. When you complete one, the next is scheduled automatically. - A gentle reminder arrives at 9am on the day something is due. STORAGE - Keep receipts, warranties, product labels and manuals so you never lose them. - Add a name, a note and up to 10 photos per item, straight from your camera or library. - Search by title or notes to find anything in seconds. - Export a photo back to your Photos whenever you need it.
