About this app

Supercycler is the app to automate indoor grows with advanced light cycles, including supercycles such as 13 hours ON / 13 hours OFF.

Unlike a regular timer, Supercycler doesn't force you to work inside the traditional 24-hour clock. You can set custom light and dark cycles — 13/13, 14/14, 15/15 or any combination that suits your grow — and the app works out the plant's real day automatically.

That means light, climate, irrigation, alerts, tasks, tutorials and monitoring all follow the cycle you configured, not the calendar.

Connect your compatible plugs, relays, sensors and cameras, set up your grow zone and let Supercycler coordinate everything from one place.

It works with the smart hardware you already own, such as Tuya, Smart Life, Shelly and Sonoff devices. You don't need to buy a proprietary controller to get started.

SUPERCYCLES: BEYOND THE ORDINARY TIMER
A traditional timer repeats schedules inside a 24-hour day. Supercycler goes further: it lets you build complete light and dark cycles that can run 26, 28, 30 hours or more, depending on your setup. For example: 13h ON / 13h OFF, 14h ON / 14h OFF, 15h ON / 15h OFF, or fully custom cycles. The app takes the moment the cycle starts and works out every switch-on, switch-off, phase of the day, alert, task and event from that rhythm.

LIGHT AUTOMATION
Program precise light cycles for every stage of the grow. Supercycler can drive main lights, secondary lights, plugs and compatible relays, with simple cycles or advanced supercycles, without recalculating schedules by hand.

CLIMATE, SENSORS AND ALERTS
Monitor temperature, humidity, VPD, CO2 (with compatible sensors) and the state of your equipment. Work with simple targets or custom ranges per stage, with alerts when things drift from what you expect.

IRRIGATION AND SUBSTRATE
Set up watering by schedule, pulses and windows within the plant's day: programmed waterings, short pulses, soak pauses, windows during the light phase, a cut-off before lights out, and moisture tracking with compatible sensors. When you use supercycles, irrigation follows that rhythm too.

STEP-BY-STEP TUTORIALS
Guided grow tutorials that show you what to do at each stage, with simple instructions organized by moment of the cycle: preparation, initial setup, daily check, cleaning, irrigation planning, preventive control, visual tracking and change logging.

PROTOCOLS AND DAILY TASKS
Supercycler organizes protocols with tasks by stage and week: what to check today, which task is due, what to write down and which alerts need attention. Tasks adapt to the actual cycle you configured.

SUPERCYCLER EYES
Turn an old phone into a grow camera: see the latest image of your zone, track how it evolves, build timelapses, overlay environment data on the video and compare changes day to day.

BRAIN: AI ASSISTANT (BETA)
Brain helps you read the state of your zone using your cycle setup, sensor data, photos, logs and tasks. It's in beta and still learning; its answers may not be exact and improve with use.

COMPATIBILITY
Integrates with devices from ecosystems such as Tuya, Smart Life, Shelly and Sonoff. Some features require compatible hardware, sensors, cameras, smart plugs or an active subscription.

Your grow doesn't live on the clock's day. It lives in its own cycle of light, darkness, climate and water. Supercycler makes the whole system follow it.
