# Atomicx7/Duo-animation > An Android demo app in Kotlin that reproduces the iPhone Duo fold/opening animation using a RuntimeShader and rotation-vector sensor data. It renders a glass pane rotating around the hinge with per-pixel blur and darkening in the gap. - Magnitude: 0.0 out of 10 — Quiet - Stars: 219 total · +0 stars on 2026-09-27 (UTC), ≈ 0 by evening - Star trust: star growth looks organic - Category: Web & frontend · Language: Kotlin · Created: 2026-09-10 · Last push: 2026-09-12 - GitHub: https://github.com/Atomicx7/Duo-animation · Page: https://gitnova.dev/en/r/Atomicx7/Duo-animation ## Useful for - Run on a physical API 33+ device to test the fold effect in real time - Tune blur and darken parameters via FoldParameters and duo_fold.agsl shader uniforms - Reuse Modifier.foldEffect() as a base for a custom fold animation in Android UI ## Why it’s here - The repository is 17 days old and already has 219 stars. ## Star trust Star growth looks organic. Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer. ## Numbers - Forks: 34 - Issues and pull requests: 6 - Watchers: 0 - Average over the last week: 0 per day - Usual pace: 10 per day - Latest release: v1.0 (2026-09-10) ## Stars per day, last 30 days (oldest → newest, today is partial) 2026-09-30 … 2026-10-29: None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None, None ## Magnitude by day, last 14 days 09-14 1.6, 09-15 1.3, 09-16 0.7, 09-17 0.8, 09-18 0.5, 09-19 0.4, 09-20 0.6, 09-21 0.4, 09-22 0.5, 09-23 0.5, 09-24 0.4, 09-25 0.0, 09-26 0.0, 09-27 0.0 --- Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score. Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast. Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
