Your Mac’s battery as a
living, breathing landscape.
A floating solar garden that shifts, flows, and evolves with how you use power. Real-time hardware telemetry and intelligent battery longevity guidance in a whisper-quiet menu bar experience.

Energy is never abstract. It flows, stores, and sustains.
Batteries are usually hidden behind cold, clinical percentages. Cyluma connects you with the energy your Mac relies on through an interactive, breathing ecosystem.
“It is a small reminder that energy is never abstract. Every percentage represents stored possibility, every charge is a renewal, and every choice shapes the world we share.”
The Luminous Reservoir
The core basin holds glowing liquid light that mirrors your current battery level from 0% to 100%. As charge rises, the depth illuminates with crystalline clarity.
Dynamic Energy Waterfall
When you plug in your charger, the waterfall cascades with vigorous aeration and bubbling current. On battery, it settles into an economic trickle or tranquil calm.
Atmospheric Shift
Day turns to afternoon amber, rich dusk violet, and starry night as charge depletes or time advances, reflecting the quiet passage of stored power.
Thriving Health Zone
Keeping your battery between 20% and 80% maintains the island in its most vibrant, lush state—helping reinforce natural habits that prolong battery lifespan.
Proactive guidance before problems happen.
Cyluma doesn’t just show stats—its Alert Policy Engine constantly evaluates hardware telemetry to deliver calm, actionable care cards right when they matter most.
Native 80% Charge Limit
Detects Apple Silicon Macs and directs you to activate the native hardware 80% limit—keeping your battery cool and healthy without brittle third-party kernel hacks.
Insufficient Power Warning
Detects when your Mac is plugged in but the battery is still discharging (weak USB-C hubs, faulty cables, or low-wattage airplane power sockets) so you aren't caught off guard.
Hysteresis Alert Engine
Zero notification spam. Alerts only re-arm when charge levels safely recover by at least 5% (crossing below 75% to re-arm 80% warning). Includes quiet hours and subtle chimes.
Every critical fact, clearly laid out.
Direct access to AppleSmartBattery registers and System Power management APIs. No vague estimates—pure diagnostic truth.
Real Maximum Health
Calculated directly against the original factory Design Capacity in mAh, highlighting service status when degradation dips below 80%.
Cumulative Cycles
Exact charge/discharge cycle counter from hardware memory, helping you track expected lifespan toward Apple's 1,000-cycle rating.
Thermal Telemetry
Live battery pack temperatures in °C with user-configurable overheating thresholds (38°C–45°C) to prevent permanent cell degradation.
Voltage & Amperage
Live electrical potential and signed amperage flow—letting you verify fast charging wattages or pinpoint silent battery drain.
Low Power Mode Aware
Seamlessly integrates with macOS Low Power Mode state via ProcessInfo, displaying system energy throttling and battery saving profiles.
Energy Drain Apps
Identifies background processes exerting significant energy consumption and links directly to Activity Monitor for instant control.
[ ADVISORY ] Telemetry metrics are queried locally via public macOS IOKit APIs for informational care guidance. Cyluma does not modify hardware firmware.
Two handcrafted visual aesthetics.
Choose between tactile clay miniature modeling or the nostalgia of anime studio hand-painted horizons.
3D Miniature Clay
A tactile, rendered isometric floating island with a glowing solar reservoir, clay-sculpted flora, and gentle architectural details. Designed to feel like a crafted living terrarium on your desk.
100% Native Swift
Written cleanly in modern Swift and SwiftUI. Zero Electron bloat, starts in milliseconds, uses under 30MB of RAM.
Zero Kernel Extensions
Runs cleanly in user space using public macOS IOKit APIs. No root daemons, no sudo commands, no system security compromises.
Pure Privacy
Zero telemetry, zero crash reporting to third parties, zero network requests. Your hardware metrics never leave your Mac.
