NerdTrack
Read full descriptionHide full description
NerdTrack records your location in a CSV file on your phone. No other data is collected and no data ever leaves your device. Full source is available at https://nerdtrack.org There is no interactive UI. Just grant location permissions, and it will log in the background. To stop logging, remove location permissions or uninstall app. The app uses the SignificantLocation and CLVisit APIs. The accuracy is low but it has very low battery usage. To get your log, open the Files app, and look for locations.csv in the Nerd Track folder. A config file will be created in the app's documents folder the first time it runs. Edit that file to change logging frequency or minimal distance. Force-stop and restart app to reload config. By default, the app records location: - Every 15 minutes, if you have moved more than 300 meters The CSV logs timestamps in the unix epoch format. Use 'dateconv -i %s' to convert it to something more human-readable. Some helper scripts are available at https://nerdtrack.org

Transform how you manage and distribute content to your mobile fleet. PupKit is a revolutionary tool that gives team leaders and managers direct control over the documents, videos, and images on hundreds of devices using one simple, powerful tool: a centralized manifest file. Stop paying for expensive content management systems. If you can edit a spreadsheet, you can command your fleet's content. THE POWER OF SIMPLICITY: HOW IT WORKS PupKit works by syncing with a single, master "manifest" file that you control. This file, easily created in any spreadsheet program (like Excel or Google Sheets), defines the entire content library for your team. Simply list your files, define their folder structure, and link to where they are hosted online. The PupKit app handles the rest, automatically syncing with your manifest to ensure every device has the exact same up-to-date information. Edit a row in your manifest to update a file; delete a row to instantly remove it from every device. It's that simple. FEATURES FOR LEADERS & MANAGERS • ZERO-COST BACKEND: Manages a fleet of any size without servers, databases, or recurring fees. Your manifest file is the entire backend. • CENTRALIZED CONTROL: Define the entire folder structure and file layout for all devices from your single master file. Ensure absolute consistency across your team. • HIGHLIGHT CRITICAL FILES: Use the "Pinned" feature in your manifest to make essential documents appear on the main screen of every user's app. • DYNAMIC UPDATES: Add, remove, or update training manuals, price sheets, or safety protocols on the fly. Changes are automatically reflected on all devices after the next sync. • RELIABLE OFFLINE ACCESS: Equip your team with the confidence that all necessary materials are stored directly on their device, available in any location, with or without an internet connection. • POWERFUL SEARCH: Users can instantly find what they need by searching filenames, keywords, or even the text inside of documents. IDEAL FOR: • Retail Chains: Deploying weekly promotions and training videos to all stores. • Field Service Teams: Ensuring every technician has the latest service manuals and safety checklists. • Educational Institutions: Distributing course materials and campus maps. • Event Management: Providing staff with up-to-the-minute schedules and floor plans.
