Two & Four
Read full descriptionHide full description
Two & Four is a private log for everyone you look after: pets, kids, the adults in your care, and the small shared money that runs a household. Open the app, tap once, and it is saved. Fed the dog, gave Grandma her evening meds, started a nap and ended it. Each day reads like a short page in a notebook, with a This Week view when you want the bigger picture. WHO YOU CAN KEEP A LOG FOR - Pets: meals, water, potty, walks, meds, vet visits, vaccines, grooming and notes. - Kids: the same quick log with human icons, and nothing pet-only. - Adults: an aging parent, a partner who is recovering, or yourself. Meals, meds, check-ins and appointments. A record, never medical advice. A PROFILE FOR EACH OF THEM Allergies, a meds list with doses, contacts you can call in one tap, and notes. Pick a med from the list when you log it, so the name and dose match what you wrote down. REMINDERS AT THE TIME YOU PICK Every day, every few days, on chosen weekdays, or once. Each one keeps the home time zone of whoever it is for, so the time stays right when someone lives elsewhere. Mark it done, skip it, or pause it. A finished one-time reminder shows as done, then moves to a Past list for 30 days. ON YOUR HOME SCREEN A widget shows when someone last ate, their last med and what is due next. App shortcuts repeat a recent log from the app icon. With App lock on, the widget and shortcuts show no names or times. MONEY, KEPT SIMPLE The Family tab has a Household card for shared ledgers, a ledger for each person, and an allowance for a child. Each one shows what is in and what is out. Records only. The app never moves money. YOURS, AND ONLY YOURS - No account and no sign up. - Your log stays on this phone. There is no cloud sync. - The app goes online only for the banner ad, store purchases and the store's rating prompt. - Back up to a file you keep anywhere, and restore it on a new phone. FREE, WITH TWO ONE-TIME PURCHASES Logging, reminders, the calendar, profiles, backups, the widget and shortcuts are free, with a banner ad at the bottom. Full unlock, a one-time purchase, adds a visit summary PDF to share with a doctor or vet, a spreadsheet export, accent themes, App lock, allowance buckets and a savings goal, and removes the banner. Remove ads, also one time, removes the banner and nothing else. A NOTE ON WHAT THIS IS Two & Four keeps records, not opinions. It is not medical, veterinary, or financial advice, and it does not replace your vet, your doctor, or your bank.
