This MasterTracker app was designed to let you track whatever you want (Entries). https://themastertracker.com/. YouTube videos, PDFs, etc. https://www.youtube.com/@MasterTracker2024. It records when, where (if wanted), what, how much, etc. and can: link to one of your contacts, show a map, add a pdf, add an image to the entry. All the stuff you want to remember in one database spot, filterable so you can find what you want by just a piece of information on the entry, like name or title, or date or a catch phrase, city, date range, etc. You can dictate to it, Copy and paste in it, etc. All features are included with the one-time purchase. No WiFi needed except to see maps and get street address first time. (Location is obtained from GPS, not WiFi) It was originally made for the patient to remember what treatments and pills, dosages, etc. were done when, and how they felt, and did various things. The treatments were extensive and overlapping and remembering all of the things going on was impossible, especially when feeling sick (Trust me, Cancer treatments put you in a fog). The notes App was not at all suitable to record things of when and where and then retrieve them later. This works easy, minimizes typing (I hate typing). Basically, when you did something, anything, you wanted to remember, just enter it in, or, if a repeated item, just pick it and click it to clone as new with Now and Here added automatically. Enter in events, like “Took Kids to the Park”, or “Had radiation treatment one of seven”, “Felt Better today, able to walk to the park” (optional Emoji Icons are yours to choose from the keyboard). “First date with Pat, went to Sushi Place” Designed for clumsy fingers, weak typists, and set to avoid mistakes. It only requires two fields, an Item Name, and a date of when it happened (Defaults to now). Helpful to record anything, from notes for a book, to things to ask somebody, to achievements, to the best place to catch fish and what conditions, etc. Can be used to track "Animals Seen" or the like and include the photo on the item so you will find it, where it was and when. Record events, milestones, feelings, ToDo's, Someday, Maybe stuff, ideas to examine later, Export the data to a standard CSV file for use in Excel, Numbers or Business Intelligence. Other concerns, I never did like paying monthly for stuff. That is why this app stores everything on your device, no monthly subscriptions. Period. One button easy to back up the data to a standard csv file and put it in an email to who you want, then hit send. The feature to link the contact to an item is great so you can put in notes and a photo, and pdf in the item and have it link to one of your contacts. the contact would have the person's name, address, phone, etc. and you can view inside MasterTracker. Some uses: I made a Category (CTG) of “PutThing” and then enter in where I put that thing in my house or computer, etc. (and was never able to find because I put it someplace “Safe”). A category list gets made as you enter in a category and then you can pick it for a list rather than type it. (Also sub-category) You can enter in old events, pick the date of it, and the location by finding on a Map in the MasterTracker, or entering an address. (it stores the GPS Latitude and Longitude then also finds and saves the written address). The GPS coordinates are entered when you save it as desired, if there is no WIFI, no problem. The written address can be updated later. https://TheMasterTracker.com Most buttons, etc. in the app can be long pressed and help to get Help on that button or text.

Stop asking, "When did I last do that?" Standard habit trackers demand daily streaks. But real life doesn't happen every 24 hours. You change the AC filter, wash the pillows, get sick, and track your cycle when it actually happens. When you try to log these irregular events in a normal app, they break your streak and hit you with a red ring of failure. SinceWhen is the "anti-streak" day counter. No guilt, no daily pressure. Just a quiet, stress-free timeline of your actual life. NEW: TRACK MULTI-DAY DURATIONS Not everything happens in a single moment. SinceWhen now supports logging durations from start to finish. • Private Period Tracking: A secure, bloat-free way to track your cycle. No pink themes, no accounts, no data harvesting. • Health & Sickness: Log exactly how many days a fever, migraine, or cold actually lasted. • Travel & Breaks: Track vacations, digital detoxes, or multi-day fasting. Just tap to start and tap to end. Your home screen tracks the current day (e.g., "Day 3"), and your interval charts will elegantly shade the entire duration. TRACK ANY IRREGULAR ROUTINE We built this for the messy, easy-to-forget maintenance tasks that streak-based apps ignore. • Home Maintenance: AC filters, deep cleaning the fridge, washing bedsheets, checking smoke detectors. • Plant & Pet Care: Unpredictable watering schedules, repotting, flea and tick medication, grooming. • Car & Life Admin: Oil changes, tire rotations, haircuts, dental visits. • Health & Self-Care: Irregular vitamins, pain relief, eye drops, replacing contact lenses. • ADHD-Friendly: A zero-shame, zero-streak visual history for executive dysfunction. SMART PREDICTIONS & INSIGHTS You don’t have to set a rigid schedule. • Learns Your Real Rhythm: Our Pattern-Aware engine calculates your natural intervals. If your routine shifts, SinceWhen instantly recognizes your new rhythm and adjusts expectations. • Interactive Calendar: Tap any day on your Insights grid to see exactly what you did and the notes you left. • Due at a Glance: See what is expected today, tomorrow, or overdue via smart, zero-pressure nudges. • Custom Time Display: Tailor exactly how time is counted—choose strict 24-hour periods or calendar midnights crossed. LOG IT IN SECONDS When your hands are full, you don’t want to tap through an app. • Interactive Widgets: 1-tap logging directly from your Home Screen or Lock Screen. • Siri Integration: Just say, "Hey Siri, log the fridge cleaning," and it saves in the background. • Apple Shortcuts: Build custom automations, or trigger logs from Back Tap. YOUR DATA, IN YOUR HANDS Your life is private, and your data stays on your device. • 100% Private: No accounts, no logins, zero data tracking. • iCloud Sync: Seamlessly syncs your logs, pins, and hidden items across your iPhone and iPad. • Direct File Access: Auto-backups save directly to your iCloud Drive Files folder (SinceWhen_Latest.json) so you can build your own custom scripts. SINCEWHEN PRO Start completely free. Track your first 3 events forever, no credit card needed. Upgrade to unlock unlimited events, full iCloud sync, Siri logging, and interactive insights: • Monthly: Includes Apple Family Sharing. • Yearly: Includes Apple Family Sharing (Best subscription value). • Lifetime: A simple one-time purchase to own it forever (Family Sharing not included). With Family Sharing (Monthly/Yearly), your entire household can track chores, pet care, and home maintenance together—each using their own Apple ID, keeping everything fully private.
