Botanic – Light & PPFD Meter

About Botanic – Light & PPFD Meter

Botanic is a practical light measurement app designed for plant growers, gardeners and indoor plant enthusiasts.

Use your phone’s light sensor to estimate PPFD, DLI and overall light intensity where your plants actually grow — on shelves, windowsills, grow tents or greenhouses.

Key features

• Measure current light level expressed as PPFD (µmol/m²/s)
• Estimate DLI (Daily Light Integral) based on exposure time
• Simple light status: very low, low, medium or high light
• Session measurements to observe light changes over time
• Spectrum view for basic light distribution insight
• Plant view to match light conditions to plant needs
• Clean, dark-mode friendly interface
• No account, no login, no subscriptions

Who is this app for?

Botanic is made for:
• indoor plant growers
• home gardeners
• grow light users
• greenhouse hobbyists
• anyone learning how light affects plant growth

You don’t need advanced equipment to understand whether your plants receive enough light during the day.

Important note

Measurements are based on your device’s built-in light sensor and provide approximate values. Results may vary between devices and should be treated as guidance, not laboratory measurements.

Why Botanic?

Most plant problems come from incorrect light. Botanic helps you quickly check light conditions and make better decisions about plant placement and lighting.

Simple. Focused. Practical.
