TrainerStack vs Kahunas

A recipe library in the client’s app, and unlimited clients for less.

Kahunas is a well-built online coaching app with a low entry price and no commission on payments. If your client list is small and you are happy uploading PDF recipes, it is good value. The gaps show up on nutrition, on the business side, and once you pass 50 clients.

Up to 25 clients
Kahunas$35/mo (Essentials). Kahunas wins on price at this size.

Checked 8 October 2026 against kahunas.io’s own pricing page and help centre, monthly billing, list price. AUD figures convert their USD price at the RBA rate of 0.6956 USD per AUD on 8 October 2026, rounded to the dollar; the amount on your statement will follow your bank’s rate on the day. TrainerStack’s A$69 is the founding-member price for the first 100 trainers, ex GST; the regular price is A$99. “Not on their published plans” means we could not find it in their published material on that date, not that it does not exist. Prices change; check theirs on the day.
