## What is Snappy?

camera that shoots without you pressing the shutter.

Sound, movement, brightness, heading, what's in frame — Snappy watches the sensors and releases the shutter the moment the condition you set is met. Use it with the phone on a tripod or a table, from a distance, when your hands are busy, or when you want to be in the picture yourself.

The shutter button still works, of course. It's an ordinary camera too.

■ Six trigger conditions

• Shake — shoots when you shake the phone
• Sound — shoots when it hears a loud noise
• Motion — shoots when something moves in frame
• Brightness — shoots when it gets brighter
• Compass — shoots when the phone faces a heading you choose
• Object — shoots when something you picked appears in frame, from 77 kinds including people, cats, dogs, birds, animals and bicycles

Most conditions can be flipped to shoot when the value falls instead. When it goes quiet, when it gets dark, when the movement stops — the reverse works too.

■ Set the threshold with your finger

The indicator just above the preview shows what the sensor is feeling right now. Drag the white line and the threshold moves with it, while you watch the frame. No need to open Settings.

■ Two trigger modes

• Continuous — keeps shooting for as long as the condition stays met
• Standby — shoots once, then waits until the condition is no longer met before it will shoot again

Choose Standby when the situation holds steady — someone standing still, a room that stays bright — so you don't end up with a hundred of the same photo.

■ Features

• Max shot count (unlimited, or 1–100)
• Interval between shots
• Automatic capture lock — the sensors keep watching, but nothing is taken
• Grid (thirds / center)
• Inclinometer showing side-to-side and front-to-back tilt at once
• Aspect ratio (default / square)
• Saved size (full / 1:2 / 1:4)
• Add location
• Capture review
• Disable Auto-Lock, so a long session isn't cut short by the screen turning off
• Front and back camera

Photos are saved to the iOS Photos library.

■ Some ways to use it

• Leave it by the door or in the garden and catch whoever — or whatever — turns up
• Clap your hands to take the shot from across the room
• Catch fireworks and lightning on brightness
• Shake the phone to shoot
• Shoot when the phone faces a particular direction

Open the Quick Guide from Description in Settings. It includes recipes like these.

### 1/5 — 最悪です早急になおせ

*2016-03-11*

アプリが起動しない早急になおせわたしの金返せふざけるな早急になおせアプリが起動しない最悪だ

### 1/5 — 起動しない

*2016-01-04*

アプリを購入したのに全く起動しません。
画面が暗くなったと思ったらすぐトップ画に戻るか真っ暗なまま全く動きません。

### 1/5 — Garbage

*2015-11-03*

App crashes on launch. 83kb app must be fake. Do not buy!

### 2/5 — 使いやすいです！

*2011-01-18*

設定画面もシンプルで、迷うことなく使うことができました。

画質は他のカメラアプリと比べるといくらか劣る部分はありますが(同じ環境下で同じ写真を撮って比べました)、セルフタイマーがついているので、こちらをメインのカメラアプリにしたいと思っています。

フラッシュのオンオフの切り替えがつけば、さらに嬉しいです。

追記
細かい文字を写真で撮ると、明らかに普通のカメラで撮るよりも画質が粗くなります（ステイブル撮影時）。
MMSで写真を添付すると、読めたものではありません。そのため星４つ→２つにさせていただきます。

### 4/5 — タイマーの音

*2010-11-14*

タイマーのカウントダウンの音が小さいです。もうちょっと大きくなりませんか？

### 3/5 — タイマー

*2010-10-22*

インカメラのタイマー欲しい(*☻-☻*)

### 4/5 — 惜しい。

*2010-08-22*

インカメラで、タイマーが使えれば
完璧です！アップデートに期待します！

### 5/5 — いいです

*2010-02-11*

本体を振ってもシャターがきれるしまたピタリと止まったときにもシャッターがきれるのでおもしろい写真もとれるし
手ぶれなしの写真も撮れるのでいいです

### 3/5 — うーん、面白いけど…

*2009-11-24*

たまに落ちるしカウントとかシャッターのボリュームが小さいのが難点ですね。
ボリュームの調節出来るようにしてほしいです。
アップデートに期待！！

### 4/5 — いい！

*2009-10-29*

なかなか3.0に対応しないので、もう諦めてましたが以前より使いやすくなって、早速メインのカメラアプリとして使っています。
タイマーで連続撮影といった使い方も出来るようになり、個人的には欲しい機能が全て詰まってます。

1つ難をあげれば、やっぱり保存時間が長い事です。
写真をキレイに保存する為には仕方ないと割り切ってますが、例えば連続撮影の場合、先に枚数を決めておいて後から保存する写真を決めるといった機能は不可能なんでしょうか？

## Version history (last 5 releases)

### 2.0 — 2026-08-13

Snappy has been rebuilt from the ground up.

■ Six trigger conditions
Shake, Sound, Motion, Brightness, Compass and Object. Object detection recognizes 77 kinds of subject, including people, cats, dogs, birds, animals and bicycles.

■ New Standby trigger mode
Shoots once, then waits until the condition is no longer met before shooting again — so a situation that holds steady doesn't fill your library.

■ Set the threshold right on the preview
Drag the white line on the indicator. You can match it to what you're actually seeing, without opening Settings.

■ Automatic capture lock
Keep the sensors watching while nothing is taken, so setting up a condition doesn't trip the shutter.

■ Also new
• Max shot count and interval between shots
• Inclinometer showing side-to-side and front-to-back tilt at once
• Grid (thirds / center)
• Aspect ratio and saved size
• Add location
• Capture review
