About Notification Log
Notification Log keeps a log of the messenger and SMS notifications your phone receives after you turn it on, organized by chat. Check what arrived before you open the messenger, and find notifications you missed. The log stays on your device.
Good for
• Checking a message first when you can't reply right away, and replying when it suits you
• Seeing new messages while you watch a video or play a game
• Skimming a busy group chat after work
Features
• Notification log by chat for messenger and SMS notifications
• Floating button: when a new message arrives, a button appears on top of other apps so you can check it without switching
• Photo gallery per chat for notifications that include a photo
• Search saved messages by person or text
• Lock the app with a password or fingerprint
• Keyword alerts for words or people you choose
• Pin up to 5 chats, block senders, clear a chat's log, save a chat as a text file
Good to know
• You see the content in the log without opening the messenger. The messenger updates read status only when you open it.
• If a message is deleted after its notification arrived, the copy already in the log stays. Messages that never arrived as a notification are not logged.
Before you start
• Only notifications received after you turn on notification access are saved.
• Messages you send are not saved, because notifications only carry received messages.
• If a messenger's notifications or message previews are off, nothing is saved for that chat.
• This app cannot show messages from another phone. It only handles notifications that reach your own device.
