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, or the language you pick in Settings), and the narrator's chain. Save favorites, share with friends, revisit history.

Detection coverage

80 everyday objects — plus scenes and places.

Lightio detects a curated set of 80 everyday objects from the COCO vocabulary that frequently appear in the Hadith corpus. Since v1.7, on-device Apple Vision scene classification adds places and landscapes — a garden, a mountain, a body of water — so a meaningful Hadith surfaces even when there's no single object to frame.

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 & scene 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

Privacy & Data settings — try it

Data Personalization
Tailor Hadith suggestions from your profile & interactions. Requires UI Personalization.
Cloud Sync

Under the hood

Modern technology, applied carefully.

We pick libraries and licenses with the same care we pick Hadith sources.

Apache 2.0
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 or scene label leaves your device. Summaries are returned in English by default; signed-in users can pick a preferred translation language in Settings, applied to every summary. The Arabic source is always preserved.

Changelog

What's new in Lightio.

A focused product, shipped in small, deliberate updates.

v1.7 June 14, 2026

Scene recognition — beyond objects

Detection now runs object recognition and scene classification together in a single on-device pass, so Lightio finds a Hadith even when there's no single object to frame.

  • Apple Vision scene classification added alongside YOLOX-M
  • Recognizes places & landscapes — gardens, mountains, water
  • "No results" is now far rarer — both sources must come up empty
  • Bounding-box overlay removed — cleaner captures, tappable chips
  • Object & scene results clearly separated, never interleaved
v1.6.4 June 13, 2026

Explicit language picker & simpler account

Translation language is now a clear in-app picker instead of being inferred from a verified phone number — the phone verification flow is gone, and privacy disclosures are tightened to match.

  • New Settings → Hadith Language picker (signed-in users)
  • Phone verification removed — phone is now optional contact only
  • Clearer email, gender & birth-date (age-bucket) handling
  • Only gender, age bucket & language sent to OpenAI when personalized
  • "Saved" confirmation toasts on profile & prayer-location updates
  • Sign-out cleanup bounded by timeout; history retention on foreground
v1.6.3 June 5, 2026

Tighter consent controls & sign-out cleanup

A privacy-hardening release — account-bound features stay behind sign-in, withdrawing consent clears its data, and cloud sync merges instead of overwriting.

  • Cloud Sync & Data Personalization require sign-in to enable
  • Cloud Storage no longer pre-checked in the Recommended preset
  • Core Hadith search works without Analytics consent
  • Sign-out clears account-bound consents & saved prayer location
  • Disabling Prayer Reminders clears the saved location (with hint)
  • History & favorites sync by union — no more overwrite

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.
