# KioKu > One photo a day. Weighted by meaning. Resurfaced when it matters most.

KioKu helps you remember it.

Capture one photo or one second of video each day. That's it. No feeds, no streaks, no pressure to document everything.

What makes KioKu different is what happens after you capture.

— YOU DECIDE WHAT MATTERS —
Right after capture, you assign a weight: Ordinary, Meaningful, or Core. That single decision — pausing to consider how much this day will matter later — is itself an act of intentional encoding. It's how memory works: meaning signals importance, and importance is what gets retained.

— WRITE TO YOUR FUTURE SELF —
Optionally, write one sentence: "What do you want future-you to remember about today?" That sentence becomes the recall hook months from now.

— MEMORIES COME BACK WHEN YOU'RE READY —
KioKu resurfaces memories on a spaced schedule based on their weight. But it doesn't just show you the photo. It shows you your own words first — and asks you to remember before revealing. This is active recall: the same mechanism used in spaced repetition learning. Retrieving a memory before re-exposure strengthens it more than passive review ever could.

— WHAT KIOKU IS NOT —
Not a social network. Not a streak tracker. Not a photo gallery. Not a journaling app.

There are no likes, no followers, no sharing. No red badges. Missing a day is fine by design. Once midnight passes, the day is over — just like in real life.

KioKu is for people who feel time moving too fast and want to hold onto what actually mattered — not everything, just the parts worth keeping.

The longer you use it, the more powerful it becomes. ## Rankings - #2,531,225 — Overall ## Permissions and access ### Permissions - `android.permission.ACCESS_NETWORK_STATE` - `android.permission.CAMERA` - `android.permission.INTERNET` - `android.permission.POST_NOTIFICATIONS` - `android.permission.READ_APP_BADGE` - `android.permission.READ_EXTERNAL_STORAGE` - `android.permission.RECEIVE_BOOT_COMPLETED` - `android.permission.SYSTEM_ALERT_WINDOW` - `android.permission.USE_BIOMETRIC` - `android.permission.USE_FINGERPRINT` - `android.permission.VIBRATE` - `android.permission.WAKE_LOCK` - `android.permission.WRITE_EXTERNAL_STORAGE` - `com.anddoes.launcher.permission.UPDATE_COUNT` - `com.android.vending.CHECK_LICENSE` - `com.google.android.c2dm.permission.RECEIVE` - `com.google.android.finsky.permission.BIND_GET_INSTALL_REFERRER_SERVICE` - `com.htc.launcher.permission.READ_SETTINGS` - `com.htc.launcher.permission.UPDATE_SHORTCUT` - `com.huawei.android.launcher.permission.CHANGE_BADGE` - `com.huawei.android.launcher.permission.READ_SETTINGS` - `com.huawei.android.launcher.permission.WRITE_SETTINGS` - `com.majeur.launcher.permission.UPDATE_BADGE` - `com.oppo.launcher.permission.READ_SETTINGS` - `com.oppo.launcher.permission.WRITE_SETTINGS` - `com.sec.android.provider.badge.permission.READ` - `com.sec.android.provider.badge.permission.WRITE` - `com.sonyericsson.home.permission.BROADCAST_BADGE` - `com.sonymobile.home.permission.PROVIDER_INSERT_BADGE` - `com.ythlium.kioku.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION` - `me.everything.badger.permission.BADGE_COUNT_READ` - `me.everything.badger.permission.BADGE_COUNT_WRITE` ## Similar extensions and apps - [Kioku – Souvenirs du jour](https://chrome-stats.com/d/com.jmarmin.kioku) — 7 users - [iMemoryKeeper](https://chrome-stats.com/d/com.ikmalsuzali.memorykeeper) — 34 users - [Memory Temple: Life & Memories](https://chrome-stats.com/d/ai.illimitable.memorytemple) — 23 users - [Kairos](https://chrome-stats.com/d/com.ratatix2207.kairos) — 263 users - [KeepOne](https://chrome-stats.com/d/fr.keepone.app) — 22 users - [Recollect - Photo Journaling](https://chrome-stats.com/d/com.recollect.recollect) — 53 users - [One' Frame](https://chrome-stats.com/d/com.one.frame.one_frame) — 21 users - [Memoria: Memory & Photo Diary](https://chrome-stats.com/d/com.techtimeapps.memoria) — 192 users - [OneSnap — Daily Photo Journal](https://chrome-stats.com/d/io.github.indieappslab.photojournal) — 722 users - [Krono: Daily Photo Journal](https://chrome-stats.com/d/com.krono.app) — 53 users - [KeepsakeIt](https://chrome-stats.com/d/io.keepsakeit.app) — 12 users - [Photo Journalizer](https://chrome-stats.com/d/com.photy.tales.pikturelog) --- Source: [Chrome-Stats](https://chrome-stats.com/d/com.ythlium.kioku)
