Ordinary calendars are made for efficiency — words, numbers, and tight grids. Moi is made to be understood. Moi Calendar is a visual schedule for anyone who needs a different calendar experience. Plan your days with pictures, video, sound, and drawings — and understand your week at a glance, even when words and lists don't work for you. A WEEK YOU CAN SEE • The whole week at a glance — day and month views too • Add photos, video, sound, and drawings to any activity • Listen to your day with text-to-speech • Plan the week together with drag-and-drop • Give each weekday its own color, so time becomes visible and predictable BORN ON A FRIDGE DOOR Moi began where thousands of families, teachers, and therapists begin every week: gluing pictures onto a week board so someone they love can see what's coming — remade from scratch every week, and stuck at home when it was needed elsewhere. Moi is that week board, in your pocket. It travels with you, next week is a rearrangement instead of a rebuild, and it does what paper never could: speak in your own voice, play video, and let you draw what's missing. Today Moi is used by autistic people and ADHDers who want structure and predictability, by people who express themselves with pictures and sound (AAC), and by non-readers of every age — children, adults, and elders alike. Often, someone who loves them keeps it up to date: a parent, a partner, a teacher, a therapist. YOURS, OFFLINE, FREE • The whole calendar works offline — no account, no sign-up, no ads • Your calendar stays on your device • Dark mode and a dyslexia-friendly font • Available in 25 languages Built in Turku, Finland since 2016, developed continuously with families, teachers, and speech therapists.
