Vehicle Maintenance Tracker vs TrueNTP

Vehicle Maintenance Tracker (VMT) is a simple yet powerful tool designed to help you keep a complete history of your vehicles’ maintenance. Whether you're tracking a single car or managing a fleet, VMT makes it easy to stay organized and informed. Key Features: *Add and update vehicle details, including photo, VIN, license plate, year, make, model, tire size, oil filter type, current odometer, and annual maintenance costs. *Set, view, and reset due dates for upcoming services. *Archive vehicles you no longer own and restore or permanently delete them at any time. *Manage maintenance records for multiple vehicles—oil changes, brakes, tires, batteries, and more. *Attach photos of maintenance receipts for better documentation. *Search and filter maintenance records easily. *Maintenance entries are organized and sorted chronologically for quick reference. *Export or email vehicle data in CSV format for printing or sharing. I hope you enjoy using VMT as much as I enjoyed building it. If you have any questions, feedback, or suggestions, feel free to reach out—and don't forget to join the **VMT community on Facebook**! It's the best way to connect with me and other users, get updates, and suggest new features. Happy Tracking!

TrueNTP measures how far your phone's clock is from true time. It queries multiple independent time servers, cross-checks their answers, and computes a corrected time with millisecond precision. You see the corrected time, your device clock's drift, and an uncertainty figure so you know how much to trust the number. WHO IT'S FOR Network admins verifying NTP infrastructure. Cell techs checking tower timing. Sysadmins chasing certificate and Kerberos clock-skew errors. IT teams resyncing air-gapped and offline systems: hold the phone next to the console and set the clock from a known-good reference. And anyone curious what time it actually is. HOW IT MEASURES • Bursts of SNTP samples to every active server, weighted by network quality (1/RTT) • Per-server offset, round-trip time, and stratum at a glance • Optional outlier rejection against the cross-server median • Six curated presets (Apple, Cloudflare, NIST, Google, Microsoft, Amazon). Enable any of them or add your own • An uncertainty readout alongside every measurement WHAT YOU SEE • A large clock showing corrected time, ticking smoothly, unaffected by OS clock changes • Turn your phone on its side for a full-screen clock face that stays awake, ready to prop up as a reference • On iPhone Duo: a larger clock when open, and the clock above the fold with the servers below when it stands half folded • Device clock card: your clock's drift, labeled plainly as DEVICE AHEAD, DEVICE BEHIND, or IN SYNC • Server list with per-server detail sheets: refid, root delay, root dispersion, per-sample scatter • 30-minute offset timeline showing your clock's behavior PRIVACY No accounts, no analytics, no tracking. Settings and history stay on your device. The privacy policy is one page. A short, plain-language NTP guide is included.
