Swimvity

Swimvity is booking and admin software for independent swim teachers in Australia: private teachers, mobile teachers who travel to families' home and apartment pools, and anyone teaching at a venue they're allowed to use. The problem it solves is simple. Lesson requests arrive by Facebook message or text, often at 9pm, and every one starts the same maths. Who's before and after? How far is the drive? Is that pool open? Can siblings go back to back? Swimvity does that checking for you. Parents get your own booking page. They say where and when suits, see only times that fit your real week, and send a request. Every time is checked against your teaching hours, your other lessons, the travel time between pools and your Google Calendar if you connect it. Nothing is booked until you approve it, and Swimvity never moves a lesson by itself. When a parent calls, Find a time shows workable options while they're still on the phone. Once families are in, Swimvity runs the routine: weekly, fortnightly and one-off lessons, school holidays and pauses, a calendar with day, week and agenda views, a waitlist, attendance, lesson payments, credit and refunds, PDF invoices and receipts, and income reports. The schedule optimiser suggests a tidier week with less driving. Families pay the teacher directly. Swimvity only records payments. It never charges cards, holds lesson money or takes a commission. Pricing is one plan, Swimvity Solo, at A$39 a month for one instructor. There's a 30-day free trial with no credit card required, and nothing is charged automatically when it ends. Teachers with ongoing lessons can book a free 30-minute setup call. Swimvity launched in October 2026 and is built in Sydney. A version for swim schools with several instructors is planned.

SynqSlot

SynqSlot is flat-rate scheduling software for individuals and small teams. Instead of charging per seat, it prices per team: Solo is $6 a month for one person, Team 5 is $27 a month flat for up to five people, and Team 10 is $35 a month flat for up to ten. Every plan starts with a 15-day free trial and no credit card is required. At its core, SynqSlot gives every host a booking page and one link per meeting type. Invitees pick a time that respects the host's connected Google Calendar, Outlook/Microsoft 365 or Apple Calendar, plus buffers, minimum notice and daily limits. Each booking creates a calendar event, adds a Zoom, Google Meet or Microsoft Teams link automatically, and sends confirmations and reminders in both the host's and the invitee's time zone. Invitees can reschedule or cancel from the email, and the host's calendar is updated on every change. Teams get the features that usually sit two tiers up on per-seat tools, included at no extra cost: round-robin and weighted distribution so leads are spread fairly across reps, routing forms that ask a few qualifying questions and send each visitor to the right person or booking link, and collective (panel) scheduling that intersects several interviewers' calendars so a whole interview panel is booked in one pick. Reschedule limits and no-show protection (invitees are asked to reconfirm before the meeting, and the slot is released if they don't) keep calendars honest. SynqSlot also includes an embeddable scheduling widget that renders on the server and works without JavaScript, so the first available times are in the page HTML on WordPress, Webflow, Squarespace, Framer, Notion or plain HTML sites. Branding can be removed on every plan. Single-use links stop working after one booking, so a forwarded link cannot be reused. Around the meeting, SynqSlot keeps a contact history with meeting outcomes, automations for confirmation, reminder and follow-up emails, and an Insights view with completion rate, no-show rate, busiest hours and top contacts. Integrations include HubSpot, Salesforce, Slack, Microsoft Teams notifications, Mailchimp, Constant Contact and outbound webhooks. A Calendly and Cal.com importer brings existing event types across with a preview before anything is created. Ask Synq, a voice and text assistant, lets hosts say "book a 30-minute call with Sarah next Tuesday at 2" and reviews the details with them before anything is created, and can move or cancel meetings the same way. Calendar credentials are encrypted at rest, data is hosted on Vercel and Neon, and the privacy policy lists every sub-processor. SynqSlot is built by Dynam Ideas Corp. in Winnipeg, Canada.
