— The stack

Three technologies we're betting on in 2026.

On-device CV for rep counting, Rive over Lottie for in-app animation, View Transitions API for native-app-like route changes. Plus the AV1 codec, scroll-driven CSS, and llms.txt for AI crawlers.

Three things sit at the front of the studio's tech radar in 2026. The studio adopts new tech only when there's a measurable user-facing or cost win — never for novelty.

Bet 1 — On-device computer vision for form correction

Running a small vision model directly on the phone to count reps and flag form issues without sending video to a server. Privacy-respecting, low-latency, zero ongoing inference cost. The tech is now production-viable on mid-range phones thanks to MediaPipe + the newest mobile NPUs.

Bet 2 — Rive over Lottie

For in-app interactive animation. Rive renders faster, file sizes are 10-15× smaller, and it supports proper state machines — not just keyframed playback. The studio is replacing Lottie in UltraFit360's onboarding flow first.

Bet 3 — View Transitions API

Now stable in Chrome and Safari. One CSS line gives a marketing site native app-like cross-document transitions. The studio is adding it to aptixlabs.com and the coach portal as a non-blocking enhancement.

Also tracking

  • Scroll-driven CSS animations as a replacement for most JS scroll libraries
  • AV1 as the new default codec for hero loops (30-50% smaller than H.265)
  • llms.txt as the emerging manifest format for AI search crawlers
  • WebGPU for browser-side inference of small models
