Picture cards make "what's next" easy to see. When kids can see it, they can do it themselves. "I did it!" feels good — and that good feeling is what makes them want to try again tomorrow. Esilbe is a picture-card schedule app that helps families ride that positive cycle together. Built on the visual schedule and structured-teaching ideas used in early-intervention settings, it turns everyday routines into a string of small "I did it!" moments. [What you can do] ■ Build the day with friendly picture cards Pick from 80+ built-in cards to put together morning, afternoon, and evening routines in seconds. Analog clock cards make "what time" easy to share, too. ■ Tap to mark each step done Each step lines up as a picture card. Tap when it's done — that's it. Simple enough for a parent and child to work through it side by side. ■ Confetti for finishing the whole day Clear every card and the screen fills with confetti and cheers. "You did it!" — the app celebrates with you. ■ A whole week, color-coded The weekly board color-codes each day so "what are we doing tomorrow?" feels exciting, not uncertain. Knowing what comes next helps kids feel safe. ■ Make cards from your own photos Snap your child's actual toothbrush, the shoes they love, the snack they always ask for — and turn them into cards. Routines built from "Hey, I know that one!" land very differently from generic clip art. ■ Calm, kid-friendly design Soft sage-green palette, rounded shapes, and reduced visual noise help kids focus on the task in front of them. Dark mode keeps things gentle around bedtime, too. ■ Streaks that grow with them A daily streak counter and monthly calendar make their effort visible. "We did it yesterday, we did it today" — something every family can smile about together. ■ Plus the basics - Keep-screen-on for uninterrupted routines - Card orientation: portrait or landscape - History log of completed days - Data stored on-device — works fully offline [Made for families who want to] - Add visual support for a child who finds words alone hard to follow - Try picture-card communication at home in a low-pressure way - Make morning prep, therapy sessions, or the school commute feel a little lighter - Cheer "you did it!" together as a family Esilbe brings the "build a sense of what comes next" and "structure the day" ideas from early-intervention practice into your kitchen and your couch, in a form anyone can pick up. Let's celebrate the small wins, together. [About usage] Core features are free. Some features are available with the optional "Esilbe Plus" subscription, offered in two plans (Monthly / Annual).
