A fitness instructor teaches six classes a week. Before each week she texts the schedule to clients. They save it, miss the pinned message, ask what time Tuesday is, and then the Thursday session moves. She texts again. Half the group sees the update. The other half shows up at the wrong time.
The fix is a class schedule app built around subscriptions. Paste the week's classes once, get a link, send the link once. Clients add it to Apple or Google Calendar. Every change flows to them automatically. No group texts for every edit, no "wait, what changed?" replies.
Calfeed is that tool.
How instructors publish a class series once
The publishing flow is the same for any class series. Type or paste the schedule in plain text: class name, day, time, location. Calfeed turns it into a live calendar feed. You get a shareable link.
Send the link to clients in whatever channel you already use: email list, WhatsApp group, studio newsletter. Each client taps the link and adds it to their calendar app. That one subscribe action wires them to your live feed. Every edit you make from that point forward reaches their calendar on the next sync.
CSV also works if you run the schedule in a spreadsheet. Drop the file into the CSV to calendar tool and Calfeed reads it the same way.
The students never need a Calfeed account. They just need the link and the calendar app they already have.
Fitness, yoga, music, dance: same pattern
The instructor-to-students pattern works across every class format.
A yoga studio publishes the week's flow sessions and workshops. A dance teacher lists recital rehearsals and open floor nights. A music teacher maintains lesson blocks and makeup slots. A personal trainer posts small-group sessions. A tutor keeps a subject schedule for multiple families.
The class timetable is different in each case, but the publishing model is identical. You control one source of truth. Clients subscribe once. Changes propagate without you nudging anyone. (For weekly classes that repeat for months, the recurring-event format handles the structure for you.)
The term "class timetable app" fits here more accurately than "class schedule app." A timetable implies a recurring structure with a live, authoritative version. That is what a calendar feed delivers. Static PDFs and group-chat pinned messages are copies. A feed subscription is the live version.
Class timetable app vs. studio booking software
Calfeed is not a studio booking platform. It does not take reservations, manage waitlists, process payments, or track who attended. Mindbody, Acuity, Pike13, and similar tools do that.
Calfeed does one thing: it turns a class schedule into a subscribable calendar link. If clients already book through an existing system, Calfeed handles the "when are classes?" side without touching the booking side. The two tools can coexist in the same workflow.
If you need just the schedule publishing piece and nothing else, Calfeed is the right fit. If you need booking as well, add Calfeed on top of whatever handles bookings. The overhead is low: paste a schedule, copy a link, send it once.
Sending a class schedule to clients without their email
The calendar link works without a direct email list. Post it in the studio's bio link, a pinned WhatsApp message, a text, or the footer of any newsletter. The recipient does not need a Calfeed account. They tap the link, subscribe, and that is the last manual step on their end.
This also covers clients who join mid-season. Send them the same link you sent at the start. They subscribe and see the full current schedule immediately. No re-exporting, no sending a fresh file. The link is the same one the original group has. Everyone stays on the same version.
Edits you make later, like cancelling a Saturday class or adding an extra session before a holiday, push to every subscriber on the next sync — Apple checks roughly hourly, Google every 12 to 24 hours (full breakdown). No separate announcement required for schedule maintenance. Reserve direct messages for same-day changes or cancellations within a few hours.
Getting started
Paste a week of classes into Calfeed, copy the link, and send it to one client as a test. Watch it appear in their calendar. That one round trip is the whole model. Scale from there — see how to share a calendar with a group for the message pattern that gets 30 clients subscribed in one round.
