WrenchLog

Getting Started

WrenchLog keeps your vehicles, maintenance history, and saved parts together. Start by adding a vehicle under Vehicles, then record work under Log Entry.

Installing WrenchLog on Your Device

WrenchLog can be used on Android, iPhone, iPad, Windows, and Mac. Open the following address on the device you want to use:

https://wrenchlog.net/WrenchLog/

Android (Google Chrome)

1. Open WrenchLog in Chrome.
2. Tap the three-dot menu in the upper-right corner.
3. Select Install app or Add to Home screen.
4. Follow the prompts to confirm.
5. Open WrenchLog from your Home Screen or app list.

iPhone / iPad (Safari)

1. Open WrenchLog in Safari.
2. Tap the Share button.
3. Select Add to Home Screen.
4. Enable Open as Web App if available.
5. Tap Add and open WrenchLog from your Home Screen.

Windows Desktop / Laptop

1. Open WrenchLog in Microsoft Edge or Google Chrome.
2. In Edge, choose the three-dot menu, then Apps > Install this site as an app.
3. In Chrome, use the install icon or the installation option in the browser menu, if available.
4. Alternatively, create a desktop shortcut pointing to the WrenchLog address above.

Mac Desktop / Laptop

1. Open WrenchLog in Safari.
2. On supported macOS versions, choose File > Add to Dock.
3. Click Add.
4. If Add to Dock is unavailable, bookmark WrenchLog in your browser.

Important: Installing WrenchLog or adding a shortcut does not automatically transfer records between devices. Follow the backup and restore instructions below.

Moving from the Old WrenchLog Address

If you previously installed WrenchLog using the old Tailscale address, your saved records will not automatically appear at wrenchlog.net. Each website address has separate browser storage.

1. Open your existing WrenchLog installation using the old address.
2. Open Backup & Restore and select Export Backup JSON.
3. Save the JSON file somewhere safe and verify that it is available before continuing.
4. Open https://wrenchlog.net/WrenchLog/ in your browser.
5. Open Backup & Restore, select your saved JSON file, and choose Restore Data.
6. Confirm the restore, then verify your vehicles, maintenance history, and saved parts.
7. Once everything is verified, you may install WrenchLog from the new address.

Important: Restoring replaces the destination's existing vehicles, maintenance records, and parts; it does not merge records. Export a backup of any destination data you need to preserve before restoring. Do not delete your old installation or its stored data until the new installation has been verified.

The original Tailscale address remains available during this transition.

Moving WrenchLog to Another Device

1. On your original device, open Backup & Restore.
2. Click Export Backup JSON and save the downloaded file somewhere safe.
3. Transfer the JSON backup file to your new device.
4. Open or install WrenchLog on the new device using the instructions above.
5. Open Backup & Restore on the new device.
6. Select your saved JSON backup file and click Restore Data.
7. Confirm the restore and check that your vehicles, maintenance history, and saved parts appear correctly.

Warning: Restoring a backup may replace existing records on the destination device. Export any records you want to keep before restoring. WrenchLog does not automatically synchronize records between devices.

Dashboard

Review the garage summary and your saved maintenance information. Open the individual tabs to see or update details.

Vehicles / My Garage

Add each vehicle's year, make, model, trim, engine, oil recommendation, and filter information. Use Edit beside a saved vehicle to update it, then choose Save or Cancel.

Renaming a vehicle also updates linked maintenance and parts entries. Keep vehicle names unique to help WrenchLog match older entries correctly.

Log Entry / Maintenance History

Select the vehicle, enter the service details and mileage, and save the maintenance record. Review your saved records to track previous work.

Parts & Fluids

Save frequently used parts, fluids, and part numbers with the correct vehicle. Search for products using Amazon, eBay, or AutoZone; these open external websites and do not place orders.

Amazon links may contain an affiliate tracking tag. See Legal & Disclosures. Always verify part fitment and specifications before buying.

Where Your Data Lives

WrenchLog saves vehicle, maintenance, and parts data in this browser's local storage. Data is not automatically synchronized across browsers or devices. Clearing browser storage can erase it.

Export a JSON Backup

Open Backup & Restore and click Export Backup JSON. Keep the downloaded file in a safe place. It includes vehicles, maintenance records, and saved parts.

Export again after important updates and before clearing browser data, changing devices, or restoring another backup.

Restore a JSON Backup

Choose your saved JSON file under Backup & Restore and click Restore Data. Read the confirmation message before proceeding.

Warning: Restoring can replace the vehicles, records, and parts currently saved in this browser. Export your current data first if you want to keep it. Click Cancel at the confirmation to stop without importing.

Common Questions

Using another device? Export a backup from the first browser, then restore it in the other browser.

Records missing? Check that you're using the same browser and WrenchLog address. If storage was cleared, restore an earlier JSON backup.

Are part numbers and fluids verified? No. Check the vehicle manufacturer's documentation for exact specifications and safe procedures.
