Both Rive muscle heatmaps just received their biggest update yet: a full female body shape, alongside the male body they’ve always shipped with. The Basic heatmap moves to v2.0 and the Advanced heatmap to v3.0 — and as always, the update is free for everyone who owns either product.
What’s new
- Female body shape (Basic + Advanced) — the heatmap now includes a female anatomy model with the same muscle coverage as the male one. Your app can finally show every user a body that looks like theirs, instead of defaulting everyone to the same silhouette.
- Refreshed male artwork (Basic) — the male anatomy in the Basic heatmap has been redrawn for a cleaner, more current look.
- New muscle: teres major (Basic + Advanced) — the small upper-back muscle that runs from the shoulder blade to the upper arm and assists the lats in pulling movements. Rows, pull-ups, and lat pulldowns can now light up the back with one more level of accuracy.
Why the female body shape matters
Fitness apps serve everyone — but until now, the heatmap showed every user the same male silhouette. Whether you use the heatmap to show which muscles an exercise trains, to visualize fatigue, or as a tappable input (Advanced), you can now match the displayed body to the user’s profile. The updated code samples in each bundle show how to display either body shape on every supported platform: Next.js + React, SwiftUI, Android Kotlin, and Flutter.
Everything else stays the same
These are additive updates. The Basic heatmap keeps its single-highlight-color, toggle-by-body-part integration. The Advanced heatmap keeps its four runtime-settable colors, the 0..4 state input, and the click-to-identify events introduced in v2.0. Your existing integration keeps working — you swap in the new .riv file when you’re ready.
How to get it
If you already own the Starter Pack, Basic, or Advanced heatmap: this is a free update. Head to your downloads and grab human_anatomy_basic_v2.0.riv or human_anatomy_advanced_v3.0.riv plus the matching code samples. The earlier versions stay on your account, so you can upgrade whenever the timing’s right.
If you don’t own it yet: the Basic heatmap is $30, the Advanced heatmap is $50 — both one-time, with every past and future version included and a perpetual single-app commercial license. See pricing →
