Harmony vs spreadsheet scheduling
A spreadsheet can track a small roster. Harmony is for studios where students move classes, teachers share real availability, and every change needs a calendar invite — without phone tag.
Short answer
Use a spreadsheet if you have a handful of students, rare schedule changes, and one person who updates the file. Switch to Harmony when reschedules are common, double-booking is a risk, or students and teachers need their own login and calendars that stay in sync.
Side-by-side
| Dimension | Spreadsheet | Harmony |
|---|---|---|
| Recurring weekly classes | Manual rows; easy to drift | One series per class; expand on the fly |
| Student reschedule | Email/text the studio | Self-serve into open slots within policy |
| Double-booking risk | High without careful coordination | Blocked by availability + conflict checks |
| Calendar invites | Manual .ics or none | Automatic email + .ics on every change |
| Access control | Shared link or one account | Role-based logins per studio |
| Daylight-saving changes | Easy to get wrong | Timezone-aware recurrence stays on wall-clock time |
When a spreadsheet is enough
A shared sheet works for a solo teacher with a stable week, or a studio that still wants every change to go through the front desk. If nobody self-serves and conflicts are rare, the overhead of software may not pay off yet.
When Harmony fits
Harmony stores each class as a recurring series, lets students pick open slots within your reschedule policy, and emails both sides with an .ics invite. Pricing is $10 per teacher per month with a 30-day trial on the first teacher — see pricing.
