Health offerings digitally — without landing-page roulette.
The market for health coaching, nutrition consulting and movement programs is full of practitioners delivering their service via Facebook groups, loose newsletters and PDF weekly plans. Works for one-off cases. Doesn’t scale. Payment happens via manual bank transfer, access via an email link that often doesn’t arrive.
For the client this was a recurring problem: she has the content, she has the customers, but the tooling is missing. Standard SaaS like Kajabi is overdimensioned and expensive for a German practice with 50–80 participants per season.
Booking. Program. Community. In one place.
The Gesundheitswochen App takes a booking via PayPal checkout, gives access to the weekly program structure (plan, exercise videos, daily reminders), and provides a private participant chat plus an end-of-week check-in. All on one site, one login.
Currently in beta with first pilot groups. Launch planned after the hosting strategy is finalised — separate Vercel account so the client project doesn’t share quota with personal infrastructure.
/ tech-decisions
Three decisions that mattered.
Payment
PayPal instead of Stripe
Client serves a 50+ audience used to PayPal checkout. Stripe would be more elegant technically, but conversion rate matters more than developer experience here.
Auth
Email + password, no magic link
Users expect classical login. Magic link confuses the audience — lands in spam, looks suspicious. Sliding-cookie keeps sessions alive 30 days from last visit.
Content
Weekly plans as MDX in the repo
Content maintained by the client through structured markdown files. No CMS, no Notion. Versioning via Git, deploy on every push.
