DogsLife turns a dog's age and your day into a plan, with six read-only tools. Potty schedule (8 to 52 weeks): how long the puppy can usually hold it, how often to go out, whether to plan night trips, and a sample day with clock times. Sleep needs (8 weeks to 24 months): typical sleep per 24 hours, how much the night covers, and how many hours of naps are left. Walks and exercise (8 weeks to 20 years): daily minutes for the dog's age, size and energy. Feeding schedule (8 weeks to 24 months): meals a day, meal times and when to switch to adult food. Adult weight (6 to 18 months): an estimate from age and current weight. Dog age: human years from the AVMA chart (up to 16 years). Same rules and sources (VCA, AKC, PetMD, Agria, Zoetis, Royal Kennel Club, PDSA, AVMA) as the calculators on dogslifeapp.com. Answers in 23 languages, with an interactive day-timeline card (MCP Apps). Read-only, no sign-in, nothing stored. Docs: https://dogslifeapp.com/connect.html
