THE EVERYDAY, RECONSIDERED
School communication should
make life feel simpler.
A trip form. A teacher update. A reminder from the office. Each matters. Kastr brings them together so a busy family can see the whole picture, and a busy school can spend less time chasing it.
A SMALL CHANGE TO THE SCHOOL DAY
From many voices.
To one clear next step.
Follow an update from the staff room to the family checklist. Then try it yourself.
Interactive illustration. Nothing here sends a message or changes a real family's records.
One briefing brings it together.
Related contributions become a combined briefing. Parents get a coherent view of school life, with the actions sitting alongside the information.
Families know what's next.
A clear checklist separates what still needs attention from what is already done. Questions stay connected to the task, so the conversation starts with context.

THE FAMILY CHECKLISTA little less
A little less
on your mind.
Try completing a task. It stays in your Completed list.
FICTIONAL SCHOOL AND FAMILY
THE DETAILS MAKE THE DIFFERENCE
Less work around the work.
More time for people.
A reminder that knows
when to stop.
Preview who still needs a nudge. Target incomplete tasks and recheck completion before dispatch, so a family that has already finished can get on with their day.
Start with the question.
Keep the context.
Parents can ask about a task or staff contribution right where they find it. Staff can see what the question refers to, instead of piecing together another email thread.
A better first day
starts with your roster.
Import school, grade and class relationships with a preview before applying changes. Review errors and family links, then bring the right people into the right school context.
Everyday updates.
Urgent news. One flow.
Send school-wide announcements, classroom updates and time-sensitive alerts by email and SMS. Keep delivery, replies and follow-up together instead of rebuilding the same message in separate tools.
Write once.
Let families read clearly.
Use each family's language preference to translate messages and preview the result before sending. Staff keep control of the wording while families receive communication they can act on.
Help families find
their people.
Create school-official or parent-led groups for activities, languages, new families and volunteering. Families opt in, volunteer admins can help, and schools retain moderation and oversight.
GOOD VALUE. BY DESIGN.

YOUR SCHOOL SHAPES THE PRODUCTIt starts with listening.
It starts with listening.
It stays focused on you.
The people running a school know what gets in the way. We listen to teachers, office teams and families, then work with schools to turn those everyday needs into a clearer, calmer experience.
Every addition should earn its place: less chasing, clearer next steps, more time for people. That is how Kastr grows around your needs while staying simple to use.
Get to know KastrA FEW THINGS WORTH KNOWING
Clear from
the start.
Can we try this with our school?
Absolutely. Tell us about your school, your families and what you want communication to feel like. We will walk through the experience with you and plan a focused introduction around your school's needs.
Do families need another app?
The parent checklist is a web experience. Families can follow a link, see outstanding and completed tasks, and ask a question in context without installing a separate app.
What does the interactive preview do?
It illustrates the contribution, briefing and checklist flow using a fictional school. You can complete tasks and explore a contextual question. It does not send messages or connect to school records.
What is the published price?
The annual per-student rate is $3.50 below 5,000 students, $3.25 from 5,000 to 14,999, and $3.00 at 15,000 or more. The calculator applies the corresponding rate to all students. See the pricing page for the full terms.
