Subscriptions, Routines, and Custom Exercises

This was a big one. Killogram now has proper billing through Stripe — subscribe for full access, manage your plan through the billing portal, and see your subscription status on the dashboard. Webhooks handle upgrades, cancellations, and failed payments automatically.

Building this took longer than expected (Stripe webhooks are... an experience), but it means Killogram can actually sustain itself as a product now.

You can now save your favourite workout combinations as named routines and load them before a session. Each routine remembers which exercises to include and your preferred settings. It's a small feature but it removes a lot of friction if you've already dialled in what works for you.

The exercise settings page got a proper overhaul. Toggle individual exercises on and off, filter by category (upper body, lower body, core, cardio), and configure which ones appear during your sessions. Each exercise now has a reference image so you can see what you're signing up for.

New this release: a real-time graph that visualises your workout intensity across a match. It plots exercise completions as a sawtooth pattern — spikes when you work, decay when you're playing. Watching it build up over a session is weirdly satisfying.
