## What is Sine?

Sine is an oscilloscope puzzle game. Match the target signal on an oscilloscope by tweaking amplitude, frequency, and phase across up to three channels.

How it works:
Dial in each channel's parameters to recreate the target waveform.
• Amplitude – wave height (0–100%)
• Frequency – wave speed (0.1–5.0 Hz)
• Phase Shift – horizontal offset (0–360°)

Easy mode gives you one channel. Medium has two. Hard has three.

Features:
• Oscilloscope graphics
• Knobs with real-time audio: hear your waveform change as you turn
• Haptic feedback on every knob for precise control
• Hint system (earn more by watching a short ad)
• Go Pro to remove ads and unlock unlimited hints

## Key features

- Oscilloscope graphics
- Real-time audio feedback
- Haptic feedback controls
- Adjust amplitude, frequency, phase
- Multiple difficulty levels
- Hint system

### 3/5 — Fun, lots of potential

*2026-02-25*

Clever concept for a game. Before I played this I thought there was going to be sound involved and I was a bit disappointed. Adding a “match the tone” element would bring this game to the next level. The knobs are difficult to adjust and it’s impossible to dial in anything precisely. When you click a knob you lose the previous setting, which makes the game harder to play (not in a good way). The graphics look good too!

**Developer response:** Hi! Thank you for the honest feedback, I really appreciate it. I've taken your comments and will be releasing an update in the near future to hopefully address all of them!

## Version history (last 5 releases)

### 1.1.2 — 2026-07-11

Updated the app store screenshots

### 1.1.0 — 2026-06-23

- Daily Streaks: track your current and longest streak of days solved. Solve a puzzle every day to keep it alive (one missed day breaks it).
- Light Mode: Sine now follows your system appearance, or you can lock it to Light or Dark in Settings.
- Accessibility improvements:
    - Full VoiceOver/screen-reader support for the tuning dials: adjust values with increase/decrease gestures, not just dragging.
    - Channel selector now pairs color with a shape (circle/triangle/square for R/G/B) so colorblind players aren't relying on color alone.
    - New "Reduce Motion" setting to turn off the waveform sweep animation.
- Streak reminders: optional daily notification (8 PM local time) if you haven't solved today's puzzle yet.
- New About screen with app info.
- Pro upgrade screen: moved from settings page to own separate page, remove ads and get unlimited hints.

### 1.0.2 — 2026-03-11

• Added haptic feedback when turning the knobs
• Improved knob control, when you click the knob it keeps your previous setting instead of resetting
• 8 bit sounds when both correctly matching the waves, as well as when incorrect
• Refined header and layout spacing throughout
• The hint reward button now works reliably
• Updated ad SDK and improved overall stability
• New app icon
