PetYearly lets us do is to appreciate how old the pet is inside, since this is often not very obvious from the outside, as pets seldom go grey or show outward signs of pain or illnesses such as arthritis. The main reason you should want to know your pet’s true age is to better understand how old they are and how they are aging. This will allow you to understand how to properly care for them and give them the best life possible. Since the 1950s, the popular calculation of how old a dog was “in human years” has been that one dog year is the equivalent of seven human years. Even though this formula has been around for a surprisingly long time, the truth is that this method isn’t entirely accurate. Not all dog breeds age in the same way. In general, we do know that smaller breeds tend to live longer than larger breeds. This app will help you to convert your dog’s age more scientifically. Besides dogs, the app can also calculate the age of a cat, horse, horse, hamster, rabbit, and guinea pig. More pets in the future.

Your life is roughly 4,680 weeks. Vitality Weeks turns that number into something you can see — a single grid where every week you've lived is filled in, and every week ahead is waiting. Open the app and the first thing you notice is where you are. Not your age in years. Your age in weeks. The dot on the grid that says: you are here. — REFLECT EVERY WEEK — At the end of each week, write a short reflection. What was the highlight? What was hard? Rate your energy. Over time, you build a private journal of your life — one week at a time. — SEAL A TIME CAPSULE — Write a message to your future self. It seals for 52 weeks. When it opens, you'll remember exactly who you were and what you were thinking a year ago. — MARK WHAT MATTERS — Add milestones to your grid — graduation, first job, a move, a loss, a win. Choose from 22 icons. Set reminders so you never forget an anniversary. — LEARN FROM HISTORY — Every week, get a notification about someone who accomplished something remarkable at your exact age. Around 12,000 facts, each chosen because you'd recognise either the person or what they did — science, art, sport, business, history — in 5 languages. — SEE TIME DIFFERENTLY — Switch between weeks, months, and years. Each view gives you a different perspective on the same life. The weekly grid is granular and honest. The yearly grid is sweeping and fast. — PREMIUM THEMES — Unlock Obsidian Gold (dark luxury) and Retro OS (System 7 nostalgia) with a one-time Pro upgrade. The free Deep Teal theme is designed to feel calm and clear. — YOUR DATA, YOUR DEVICE — Everything is stored locally. No accounts. No cloud. No tracking. No ads. Your reflections, capsules, and milestones never leave your phone. — FEATURES — • Life grid: weeks, months, or years • Home screen widget (5 sizes) • Weekly reflections with energy tracking • Time capsules (52-week reveal) • Milestone tracker with icons and reminders • Age-based historical facts • 3 premium themes • Up to 2 profiles • Works fully offline • 5 languages: English, Japanese, Spanish, Portuguese, Korean A different way to look at time.
