MayDiary is your personal space for safe and smart journaling. It combines classic diary writing with cutting-edge artificial intelligence technologies that help you better understand your experiences, emotions, and life patterns. KEY FEATURES: AI ANALYSIS & TRENDS: Get intelligent summaries of your past week, month, or year. MayDiary analyzes your moods, identifies key moments, and uncovers trends you might otherwise miss in regular text. SMART TRANSCRIPTION: Capture your thoughts faster than you can forget them. Use Apple’s lightning-fast local transcription or the advanced OpenAI cloud engine for precise formatting of dictated text. SMART TAGS: Organize your entries with fully integrated tags throughout the app. Add tags manually or let AI suggest them. You can then filter by tags or use them for more accurate AI analysis. NATURAL SEARCH: Can’t remember when you wrote about something? Just ask. The AI filter finds entries based on their actual meaning and topics, not just exact words. PRIVACY FIRST: Your diary belongs to you alone. Data is securely stored in the app’s sandbox and protected by iOS system encryption. If you use sync, entries are saved to your private iCloud database linked to your Apple ID. You can also secure access to your diary with Face ID or Touch ID. MODERN EDITOR: Enjoy a clean and clear environment with Markdown support for perfect structure in your notes. NO ADS, NO DATA COLLECTION: MayDiary was created as an independent project with a focus on user experience. The app is free, contains no ads, and your texts are never used to train AI models. WHY MAYDIARY? Unlike ordinary diaries, MayDiary helps you find meaning in your writing. It’s a digital companion for personal growth that holds up a mirror and provides practical recommendations for your wellbeing and mental health. NOTE: To use AI features, you will need your own OpenAI key. Instructions can be found directly in the app.

VitalLedger keeps every record of your pet's life, and keeps it yours. One app for every vaccine, vet visit, medication, weight, symptom, meal, walk, expense and memory. No ads, no account, no data resale. Your records live on your iPhone first. NEW: THE DAILY LAYER Log a meal, water, potty break, litter box, mood or sleep in one tap — from Today, the Home Screen widget, Control Center, the Action button, Siri or your Watch. See who fed whom, with a warning before anyone feeds twice, and mark a dose given from the Lock Screen. A gentle streak, no nagging. NEW: IT READS THE RECORD BACK TO YOU Ask about weight changes, past visits or what you've spent, and get answers drawn from your own records. It runs on your iPhone — nothing is sent to a server. NEW: SCAN IT, RECORD IT, REVIEW IT (PREMIUM) Photograph a vaccine certificate or invoice, every page: VitalLedger reads each record on it, the clinic and the total, and you check them before anything is saved. With your vet's permission, record the appointment: transcribed on your device, summarised into the visit, with medications and follow-ups ready to save. Plus a short summary of each pet's week, written from what you logged. NEW: LOST-PET MODE One toggle turns your pet's Wallet pass red with your number on the front, and gives you a poster to print and share. And when a pet passes away, their record stays — every photo, every visit — and simply leaves your daily screens. A REAL MEDICAL TIMELINE Vaccines, visits, medications, lab PDFs and treatment notes in one chronological record. Attach the paperwork as a photo. Every visit can create its expense. Add due dates to your Calendar, pick your vet from Contacts. MORE WITH PREMIUM VitalScore, one wellness number per pet with the full formula shown. A preventive schedule built from species, breed and age. A one-page brief for your appointment. Symptom triage, with a photo, showing how urgent it looks given your pet's history — never a diagnosis. Recall alerts quoting the official notice, matched on your device. Insurance claims tracked against what the policy costs. WEIGHT, WALKS AND REMINDERS Trend charts with a goal range, plus body condition on the 1-9 scale vets use. Time a walk and it's saved with the distance. Reminders for vaccines, medications, checkups and grooming. PHOTO JOURNAL, SITTER MODE, PET ID Albums for birthdays and recoveries. A read-only card with feeding times, medications and vet info — no app or account for your sitter. A pet ID in Apple Wallet and a printable card with microchip and emergency contacts. BUILT FOR iPHONE, iPAD AND APPLE WATCH A real iPad sidebar, not a stretched phone layout. Quick-log from your wrist, Live Activities for medication courses and walks, tap-to-log widgets, Control Center and Action button controls, pets in Spotlight. In English, Spanish, French, Brazilian Portuguese and German. WHAT'S FREE Up to 2 pets, 5 active reminders, and the last 12 months of history. Every log and record type — including daily care — the Watch app, widgets and controls, Siri Shortcuts, lost-pet mode, and full backup and restore. Always, with no account. PREMIUM $2.99/month, or $19.99/year with a 7-day free trial. It lifts the limits — unlimited pets and reminders, full history, iCloud sync, CSV export — and adds everything marked PREMIUM above, plus Family Sharing, PDF reports and custom fields. No ads, no data resale, no forced sync, no urgency timers. Backup and restore are never paywalled, so your records can always leave with you. Their records. Your control.
