How it works

Three steps. Zero apps to install.

Tell Kaira your goal, your equipment, the time you have. It builds the plan and shows up daily in WhatsApp.

Set your goal

30 seconds, in WhatsApp. Running, strength, or home — you pick.

02

Get your plan

Adapted to your level, your equipment, and the time you have this week. All in the thread.

Train 24/7

Send questions, voice notes, or a photo of the gym. Reply on the spot — day or night.
