Lightstick Controller
Entertainment
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Control BLE (Bluetooth Low Energy) lightsticks (penlights) from your smartphone. Pick colors, build light shows synced to your songs, and even run two lightsticks on separate lines — all in one app.
■ Real-time color wheel
Drag the color wheel to pick a color, and your lightstick changes instantly. HEX input, 12 preset colors and favorites are supported, and brightness goes from 0 to 100%. "Rainbow" keeps the colors flowing without picking one.
■ Lighting patterns
Off, Solid, Blink, Fade In, Fade Out, Pulse, Inverse Pulse and clap patterns (PPP / Pa-pan), with adjustable cycle time. Two-Color Mode alternates between two colors.
■ Scores for automatic light shows
Build color changes on a timeline as a "score": set the color, brightness, pattern and length of each cue, then play the show with one tap. Work in seconds, or by BPM and note values. Copy and paste cues, repeat groups, pause and jump during playback, and add a start delay with a countdown beep.
■ Two lightsticks on separate lines (Plus)
Connect two lightsticks and give each its own show with a score's Line 1 and Line 2. Swap which one is Line 1 on the connection screen; playback shows both colors and timelines side by side. Single-line scores send the same show to every connected lightstick.
■ Play in sync with music (Plus)
Link a song from your music library to a score to play music and lights in sync. "Check BPM" analyzes the whole song for its exact tempo, which you can apply to the score.
■ Auto-generate scores from music (Plus)
Analyze a song to create a light show that follows its structure. Choose the range to analyze, then edit the result in the editor.
■ Setlists for full shows (Plus)
Arrange scores in song order as a "setlist" and play a whole concert automatically, with adjustable gaps between scores.
■ Music Reactive
Analyzes music in real time as it plays and changes your lightstick's color and brightness to its frequencies and beats.
* Song analysis (Check BPM, auto-generation, Music Reactive) works only with songs that are not DRM-protected, so Apple Music streaming tracks cannot be analyzed.
■ Share scores
Export scores as JSON files to share them (export requires Plus). Importing works on the free plan too (up to 30 seconds). Two-line scores require version 1.10 or later.

- FRUITS ZIPPER OFFICIAL FAN LIGHT
- KING BLADE X10 V (Color Tuning Mode)

Ratings & Reviews
Auto-detection for lightsticks that aren't on the supported list is now more reliable.
- Auto-detection: the app now checks that your lightstick changes to green, blue, and red before saving the setting. It tries several formats at once, so you answer fewer questions
- Long-press a connected lightstick to recheck the color format that auto-detection chose
- Cancel while connecting. If a lightstick can't connect or Bluetooth is off, the app tells you why
- Added a Website link under Support in Settings
- Music Reactive: set the start position with the same buttons as the score editor
- More consistent colors and easier-to-read text throughout the app
- Bug fixes, including KING BLADE blinking after auto-detection
- Updated Help for the latest features
