Everything the app does today.
This page lists only what is in the current development build. New items from the latest update are marked.
The basics
One choice per app
Immediately, hold, at delivery time or block. Rules can also apply to an app group or a category.
Delivery times
Set several delivery times a day, such as 12:30, 18:00 and 21:00. Everything waiting arrives together.
Never hold list
Apps you add here come through in every mode. Optionally, get one more reminder if a notification is not opened within five minutes.
Always delivered
Calls, missed calls, alarms, reminders, calendar and navigation notifications are never held.
Quiet summary New
One silent line in the notification bar, with no sound or vibration, shows who has how many notifications waiting and when the first one will arrive. Content is not shown. Turn it on for the apps you choose or for everything that waits. A “Deliver now” button gives you everything waiting at once, without opening the app.
Modes and plans
Four modes, plus your own
Normal, Focus, Sleep and Sports. Rename them, hide the ones you don't use, or create your own modes.
Who comes through, who waits New
For each mode, see which apps arrive right away and which wait, with the reason. Add an app, group or category to say “this one comes through in this mode”.
Weekly plan and calendar New
Modes switch by day and time. Browse months and years, see how many notifications arrived, waited and were delivered on a past day (counts only), and set a plan for a future date. Date-specific plans are listed with their dates. While editing a plan, pick weekdays or the weekend with one tap.
24-hour dial
The Today screen shows the whole day on one ring with the waiting notifications. A countdown shows when the next delivery comes, for example “5 notifications in 38 min”.
Shift schedule
A repeating cycle of morning, evening and night shifts and days off. Breaks inside a shift are applied too.
Ready-made profiles
Preview what a profile changes before you apply it, and edit it. A profile lasts as long as its name says (for example “Deep work · 2 hours”) and then returns to the previous mode.
Focus session New
Tap “Focus for 25 min” on the Today screen. When time is up, you go back to your previous mode and see a short “well done” summary (counts only).
Staying in control
Rule scope New
See which apps a rule such as “Shopping” covers. Remove an app that was guessed wrong, or add a new one.
App groups
Put apps into groups and manage them with one rule. Rename a group or change its apps at any time.
All your apps
The Rules screen lists every app on your phone, not only the ones that have already sent a notification.
Optional automations
With your permission, the app can switch modes during calendar meetings or when your phone connects to your car over Bluetooth.
Back up your rules New
Save your rules to a file and restore them later. The backup also keeps mode names, hidden modes and each mode's list of apps that come through right away.
Smart setup New
Setup starts by getting to know your phone: your apps are sorted into groups, and you fix any that land in the wrong one. You are only asked about groups you actually have, and at the end you see a preview of who comes through and who waits. Choose “Start simple” and setup ends in 3 steps with the simple view turned on.
Weekly clean-up suggestion New
The Today screen lists the apps without a rule that interrupted you most this week. Move one to delivery time with a single tap, or choose “Not now”. Only counts are used.
Simple view New
Turn it on in Settings: the Today screen keeps only the dial, a single “Focus / Back to normal” button and the waiting notifications. The Rules and Plan tabs are hidden, and your rules keep working in the background. For people who want to use the app with as few settings as possible.
Why did it wait? New
In History, every held notification shows which mode or rule held it. From there you can also move that app to delivery time without opening the rules screen.
Question of the day New
Once in the morning, the app asks about the app without a rule that interrupted you most yesterday. Hold it with a single tap.
Mode by Wi-Fi New
Normal when you get home, Focus when you arrive at work. You set it up with your phone's routines app (on Samsung, “Modes and Routines”); ha!shh does not ask for location permission. Settings → Mode by Wi-Fi shows the steps. Home screen shortcuts and routines switch the mode without opening the app; only a short message appears.
Archive and security
Notification archive New
Save the notifications you want into folders such as Coupons, Bills and Expenses, or your own folder. The app suggests the amount and you confirm it; a monthly total is shown. Add a due date and you get a reminder that morning. You can also archive a notification straight from History if its content was kept there. Nothing enters the archive on its own. An item with a due date can be added to your phone's calendar (no calendar permission needed).
Fingerprint lock New
Protect the whole app, or only the archive and notification contents, with your fingerprint, face or phone PIN. Android's own prompt is used, so your fingerprint data never reaches the app. In the “archive and contents” setting, content previews in History also stay hidden until you unlock.
See content, only if you allow it
Notification content is not read by default. Turn on content display in Settings to see what is waiting.
Themes and app icon New
Choose Paper (warm cream, the default), Light (white), Dark or System, which uses Paper in light mode and Dark in dark mode. When you change the theme, the app asks whether to match the home screen icon too. On Android 13 and later, themed icons take your wallpaper color.
Send feedback New
From Settings, your email app opens with a ready message. Adding device information is optional.
