PlainHygiene

PlainHygiene is a reference library of practical, sourced hygiene guidance — 1,088 features across 18 topics, from WHO's 6-step handwashing technique to menstrual health, food safety, disaster sanitation, and caregiving for kids, elders, and people with chronic conditions. Every fact is drawn from public health authorities: the World Health Organization, the CDC, UNICEF, USDA, OSHA, EPA, FDA, FEMA, the Sphere Association, and similar bodies — with citations you can check yourself, right in the app. WHAT'S INSIDE • Handwashing & hand hygiene (WHO's 6-step technique, a guided timer, hand sanitizer guidance) • Menstrual & reproductive hygiene • Food hygiene & safe handling • Body & personal hygiene • Sanitation infrastructure & waste management • Life-stage hygiene: infants, kids, teens, pregnancy, elders • Low-water, disaster & emergency hygiene • Disease prevention & hygiene science • Household, laundry & environmental hygiene • Occupational & workplace hygiene • Travel, outdoor & camping hygiene • Pet, animal & zoonotic hygiene • Community, school & public-space hygiene • Special populations, disability & chronic-condition hygiene • Culture, language & localization notes • A full reference library & glossary Plus routine-building, reminders, and habit-tracking tools to turn any of this into a daily practice — at your own pace, with no streak-shaming. BUILT DIFFERENTLY • Works completely offline. Every fact ships inside the app — nothing loads from a server, because PlainHygiene doesn't have one. • No account, no login, ever. • The app shows ads served by Google AdMob; a one-time Remove Ads purchase removes them. No account needed. • The only network calls this app can ever make are opt-in, unauthenticated fetches of public WHO/World Bank hygiene statistics — off by default, and nothing about you is ever sent when you turn it on. • Build routines, set reminders, track streaks, add a step to your calendar, and export or print your data — all stored only on your device. • A home-screen widget, a lock-screen tip-of-the-day widget, and an Apple Watch companion app with a guided handwashing timer. PLAINHYGIENE PRO 531 features are free, permanently, with no catch. PlainHygiene Pro ($1.99/month, auto-renewing) unlocks the remaining 557 deeper-dive features — extended technique guides, additional reference material, and advanced tracking tools — across every topic. Subscriptions auto-renew unless cancelled at least 24 hours before the end of the current period; manage or cancel anytime in your Apple ID account settings. Payment is charged to your Apple ID at purchase confirmation. A NOTE ON WHAT THIS APP IS PlainHygiene is educational hygiene guidance, not medical advice — it's not a substitute for professional medical advice or local public-health guidance. If you have a health concern, talk to a qualified professional. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
