It checks in
The trainer who messages first
A message every day about what's next. Once a week, a five-minute review that agrees one small change.
- Your goal stays on file when it eases the plan.
- Your streak counts good weeks, so one bad day can't break it.
- Miss the review and you get one nudge, then it stops.

I'd rather you nail three sessions than miss four, so let's do three this week. Your goal of four stays on file.

When can I start?
We invite people from the waitlist to the beta in batches from November. Streka launches in January 2027. We will email you when your invite is ready and when Streka launches.
What does it cost?
Free to start. Coach is £24.99 a month from launch. The first 150 beta members get a founding price, locked for as long as they stay.
Is my trainer a real person?
No. Every Streka trainer is an AI, it tells you so when you meet it, and it never pretends to be a person.
Which phones does it work on?
The beta starts on iPhone, through Apple's TestFlight app. We will tell the waitlist when Android is ready.
Do I need a gym?
No. Your training plan is built for the days you can train and the equipment you have, from a full gym to bodyweight only.
Is it medical advice?
No. Streka gives fitness and nutrition guidance. It doesn't diagnose or treat anything, and it tells you when something is for your GP.
What happens to my email address?
We use it to email you when the beta opens and when Streka launches, and for nothing else. We don't sell it, and you can unsubscribe at any time. The details are in the waitlist privacy notice.
