Interval bells that let a sit stay unwatched

A sit fails in a small, ordinary way: you open one eye to see how much time is left. The remaining minutes become a negotiation. The phone, which was supposed to be a fence, becomes a dashboard.
Interval bells exist so you do not have to look. They are not entertainment. They are markers on a path you already chose.
This is a note about how Mantra Time uses them on the actual meditation screen, not a survey of every timer on a store listing.
The screen before you sit
The meditation screen is titled "Make a little room." Under that: choose a length, set gentle markers, and begin. The timer remains accurate with the screen off.
You set three things, then you put the phone down.
Duration first. Presets are 5, 10, 15, 20, and 30 minutes. A custom field takes anything from one minute to four hours, so a lunch-break sit and a long evening sit use the same object.
Then interval bells: No bells, Every 1 min, Every 2 min, Every 5 min, Every 10 min. That is the whole list. Then a tone: soft chime, singing bowl, temple bell, wood block. Begin session is the last control. After that, stop touching the device.
Why a marker is not a second timer
An end bell says: the sitting is over. An interval bell says: you are still in it.
People ask for intervals when they lose the plot in the middle — the mind has gone to a message, a kitchen sound, a plan for later. A quiet mark at five minutes is a hand on the shoulder. It is not a grade.
Intervals become a second timer when you start using them to check whether you are "doing well." If you find yourself waiting for the next chime the way you wait for a progress bar, set the interval to none. A single end bell is a complete tool.
This is the same honesty as counting japa without a streak. A mark should close a unit of attention, not open a case against you.
How to choose none, 1, 2, 5, or 10
No bells is the default for anyone who can sit without a middle marker, and for anyone in a house where extra sound would be a broadcast. If you are following a recitation with a minute of quiet, as in Hanuman Chalisa practice, none is usually right. The verses already have their own shape.
Every 10 min is for a longer sit that needs one or two reminders that time is still moving, without chopping the sitting into slices. A thirty-minute evening sit with a mark at ten and twenty is a common, boring choice. Boring is useful.
Every 5 min is the middle of the list and the one people pick when they are unsure. It is enough structure for a wandering morning. It is too much structure if you start counting the bells instead of sitting.
Every 2 min and every 1 min are for short sits, or for days when the mind is loud. They are a poor choice for a sit you want to disappear into. A bell every minute on a twenty-minute sit is a metronome. Use it on purpose, not as a habit of anxiety.
If you are new, start with none or every 5 min on a 10 or 15 minute preset. Change one variable after a week, not three in one evening.
Tones that belong in a house
The four tones are not a brand exercise. They are the smallest set that covers a quiet room and a noisy one.
Soft chime is the least theatrical. It is the one to try first if other people are in the house, or if you startle easily at the end of a sit.
Singing bowl has a longer body. If the bowl becomes the practice, switch to the chime.
Temple bell is clearer. Useful if the fan is on, or if you sit in another room from the phone. Less useful at 5:30 a.m. in a thin-walled apartment.
Wood block is dry and short: a tap, not a mood. If you dislike "spiritual" sounds, this is the honest option.
Pick the quietest tone you will still recognise with eyes closed. Then stop picking. A prayer reminder should not use the same sound as a package alert, as in prayer reminders that do not feel like notifications. The meditation bell has the same job: be recognisable, then go quiet.
Unwatched means the screen can go dark
The copy on the screen is a constraint we actually built to: the timer remains accurate with the screen off. Interval bells that depend on an app loop often die when Android suspends the process. Bells that are scheduled as real times of day survive a locked phone in another room.
You should not have to become a systems engineer to sit. You should also not have to keep the screen on "just in case." If you do not yet trust a timer, do the small test in a meditation timer that stays accurate when the phone sleeps: set ten minutes, lock the phone, walk away. If the bell does not arrive, do not take that tool into a real sitting.
What we refused on this screen
There is no library of rain, no social share at the end of the sit. The meditation screen is a clock with a few markers. There is no streak on the other side of the bell. The session can be stored later in a private history if you want a trace. It does not scold you for twelve minutes when you had meant twenty.
We also refused a custom interval field. Four steps are enough. Custom would invite tinkering.
A way to use this without fuss
For a month, try one shape:
- Pick a duration you can finish on a weekday — often 10 or 15 minutes.
- Set interval bells to none, or every 5 min if the middle of the sit usually dissolves.
- Pick one tone and leave it.
- Begin, put the phone face down or in another room, and let the marks be the only time the device speaks.
- If you stand up early, end the session on purpose. Leaving a timer running so the log looks complete is the same dishonesty as inflating a japa count.
If the bells annoy you, they are too frequent or too loud. Turn them off before you turn the practice off.
A kitchen timer still works. Interval bells in Mantra Time are for the case where the phone is already in the room and you need it to behave like a clock.
Make a little room. Choose a length. Set gentle markers if they help. Begin. Then do not watch.
FAQ
Do I need interval bells to meditate?
No. Many sits need only an end bell. Intervals are for people who drift and want a quiet marker, not a second clock to manage.
Will the bells still ring if the screen is off?
That is the design constraint. The timer is built to stay accurate with the screen off. Test it once without meditating if you do not yet trust the device.
Which tone should I pick?
Pick the quietest one you will still recognise with eyes closed. Soft chime and singing bowl are gentler in a shared house. Temple bell and wood block cut through more noise.
