How it works

From the world around you, to the words of the Prophet ﷺ — in three taps.

No typing, no remembering keywords. Just look, capture, learn.

01 · CAPTURE

Point your camera

Open Lightio anywhere — your kitchen, the masjid, the garden. Frame the object you're curious about and tap the shutter.

02 · DETECT

On-device AI does the work

Lightio runs YOLOX-M locally on your iPhone's Neural Engine. Your image never leaves the device — only the resulting label does, when needed.

03 · DISCOVER

Read, save, reflect

Receive an authentic Hadith with the Arabic original, an AI translation (English by default, switching to your country's primary language once you verify your phone number), and the narrator's chain. Save favorites, share with friends, revisit history.

Detection coverage

80 everyday objects from the COCO vocabulary.

Lightio's detection model recognizes a curated subset of objects that frequently appear in the Hadith corpus — from food and animals to household items.

Features

Everything you need to learn — nothing you don't.

Each feature is opt-in. You decide what Lightio does, and what stays private.

Prayer Reminders · New in 1.6

Accurate prayer times, wherever you are.

Eight calculation methods covering Muslims worldwide — from the Muslim World League to regional presets for the Gulf, North America, South Asia, Iran (Jafari), and Indonesia.

Adhan algorithm, on-device

Times calculated using the widely-trusted Adhan library. No round-trip to a server, no tracking.

One-time location detection

We ask for your city, country, coordinates, and time zone exactly once. You can update or revoke it anytime.

Asr calculation choice

Pick Standard or Hanafi — framed as calculation behavior, not madhab identity, so it stays neutral and works for everyone.

Works in every region

From Makkah to Toronto, Jakarta to Istanbul — Lightio picks the right calculation for your latitude automatically.

Privacy by design

You're in control. Always.

Lightio defaults to the minimum. Everything beyond core detection — analytics, personalization, cloud sync — requires an explicit opt-in you can revoke at any time.

  • Images processed locally — only object labels leave the device
  • Five independent consent toggles, granular and clear
  • Full GDPR rights — access, export, delete, anytime
  • 72-hour breach notification policy
  • Sign in with Apple — no password to remember

DETECTION

YOLOX-M

State-of-the-art object detector, ~31% smaller than the previous YOLOv7 build. Runs locally on the Apple Neural Engine.

Open source
PRAYER TIMES

Adhan algorithm

Calculates Fajr, Dhuhr, Asr, Maghrib, and Isha from latitude, longitude, and time zone. Supports Muhammadiyah, Kemenag, and Hanafi rules.

Encrypted
HADITH SEARCH

OpenAI backend

Only the detected object label leaves your device. Summaries are returned in English by default; once you verify your phone number, Lightio infers your country from the dialing code and routes summaries in that country's primary language. The Arabic source is always preserved.

Yogie & Ami

CREATORS · LIGHTIO

Hi, I'm Mohammad Sani Suprayogi (Yogie), and together with my wife Ami, we are the small team behind Lightio. We started this project in Yogyakarta, Indonesia, but built it for the global Ummah — making the rich Hadith tradition accessible to anyone, anywhere, through something as ordinary as a phone camera.

We believe Islamic learning should feel personal, calm, and curious — no matter where you live, what language you speak, or which madhab you follow. Lightio is our small contribution toward that.
