SyncroLog

A time-logging app for Android designed to aid synchronicity research. SyncroLog records the exact date and time whenever a user notices the clock on their phone, building a dataset to analyze whether certain times appear with statistically unusual frequency. By Jason Page — Amfile.org

Purpose

Many people report seeing specific times repeatedly (11:11, 12:34, 22:22, etc.). SyncroLog provides a simple, structured way to collect this data for analysis. Each time you glance at your phone and notice the time, open the app and tap a single button to log it. Over time, the app reveals patterns in which times you observe most frequently.

Features

• One-tap logging — Large "LOG THIS TIME" button records the current time instantly
• Live clock — Prominent monospace time display updates every second
• History view — Scrollable list of all logged entries with date and day of week
• Frequency analysis — Ranked view showing which HH:MM times you see most often
• Pattern detection — Automatically tags notable times:
- Repeating — 11:11, 22:22, 00:00 - Mirror — 12:21, 10:01, 23:32 - Sequential — 12:34, 01:23, 23:45 - Double — 12:12, 10:10, 23:23 - Angel Number — 1:11, 2:22, 3:33, 4:44, 5:55
• Background mode — Persistent service automatically logs whenever the screen wakes (power button, double-tap to wake, lift-to-wake). Toggle on/off from the main screen. Survives reboots.
• 60-second cooldown — Prevents duplicate entries when rapidly toggling the screen
• CSV export — Share or save your log data via Android's share sheet
• Entry management — Long-press to delete individual entries, or clear all data
