How we work
No ads, no tracking.
Our software shows no ads and runs no analytics. This website counts visits without cookies. Tabdial and the two calendars keep what you save on your device. The shift app keeps schedules on our server only to back them up and share them between phones, and deletes them when you delete your account.
Free stays free.
Each product is free to use, and what is free stays free. Extras are a one-time unlock (US$9 for Tabdial, ฿149 for the Thai calendar). Only the shift app has a subscription, because its sync and staff links run on our servers every month.
Real answers by email.
Your email is read and answered where the software is built, so a bug report turns into a fix. No forms, no chatbots, just email.
