TAKT

What Takt is

Every cycle shows you more of you. Only you.

Takt records your period, shows you your patterns and tells you what comes next — and shows you how it got there.

One cycle in fast forward: hollow dots are computed, filled ones measured.

Takt is for you if you want to understand your cycle and know where the numbers come from.

The app in your hand

Your everyday

Three surfaces that come up every day — the sheet, the month and what other people see. Each one is here to be handled, not described.

Three surfaces — pick one

Fits into any gap

Cramps since this morning.

The sheet shows only what you want to record.

One day, one sheet — and no save button.

You see what is coming

On edge for days.

The outlook names what is coming — and in how many days.

Your signs sit on top — one of your choosing.

You show what you want to

Your phone is lying there, open.

How much appears on your home screen is your choice — from everything to nothing.

The app itself can be locked — the widget cannot.

A detail of the app’s empty entry sheet: at the top the note that entries save automatically, below it the basal body temperature row with an empty field, then bleeding as five drops from none to heavy. Under “symptoms” there are only four tiles — cramps, fatigue, bloating, mood swings — and beneath them the notes field comes free; nine further symptoms are switched off. A detail of the app’s empty entry sheet: at the top the note that entries save automatically, below it basal body temperature with an empty field and bleeding as five drops from none to heavy. The full list of symptoms follows straight after and runs past the bottom edge of the picture; cervical mucus, hot flushes and night sweats are hidden. A detail of the app’s empty entry sheet: basal body temperature, bleeding and cervical mucus with its four levels of dry, creamy, watery and stretchy, and the symptom tiles below. Hot flushes and night sweats are hidden, and nothing has been recorded. A detail of the app’s empty entry sheet with every row: basal body temperature, bleeding, cervical mucus, hot flushes and night sweats, the last two each with the levels mild, moderate and severe. Nothing has been recorded. A detail of the app’s calendar on cycle day 1: the outlook card gives fertile in 7 days, ovulation in 13 days and the period in 28 days. In the August grid, today’s 17th carries the marker for cycle day 1, and the computed window at the end of the month is outlined hollow. A detail of the app’s calendar on cycle day 12: the outlook card gives fertile now until 21 August, ovulation in 2 days on 19 August and the period in 17 days on 3 September. The measured period days at the start of the month stand solidly filled, the computed fertile window is outlined hollow, and the ovulation band is dashed. A detail of the app’s calendar on the day of ovulation, cycle day 14: the outlook card gives fertile now until 19 August, ovulation today on 17 August and the period in 15 days on 1 September. The same calendar on cycle day 12, now with the sign Cramps in the grid: on the three period days at the start of August each day circle carries a small mark at its top right, and the other days carry none. The same calendar on cycle day 12, now with the sign Mood swings in the grid: the marks sit on the five days before the period, not on the period days themselves.
TAKT

For your eyes only

The medium Takt widget on a home screen: on the left, fertile with ovulation in 2 days and the period on 3 September; on the right, the ring of dots with 12 as the cycle day. The same medium widget on the Quiet level: only the ring of dots with the figure 12 is left; phase and forecast are gone. The same medium widget on the Mute level: no figure any more, just the ring of dots with one bright dot and a line inviting you to record your first day. The small, square Takt widget on a home screen: the ring of dots with 12 in the middle. The same small widget on the Quiet level: the ring of dots with 12 — the same picture as on Open. The same small widget on the Mute level: the ring of dots with no figure, just one bright dot in it.

How certain this is

Measured or computed.

Without temperature and mucus, your ovulation is computed from your rhythm, not measured. How narrow the forecast gets is down to your cycles alone.

Your patterns

No pattern yet Starting to show 5 of 6 cycles 5 of 6 cycles

Four situations — pick one

One cycle behind you. So far you have recorded only your bleeding — no thermometer, no mucus. Three cycles behind you, and they are still uneven. You have recently started taking your temperature in the morning. Six cycles behind you, and they barely vary. You record both temperature and mucus. Six cycles behind you, and they vary a great deal. You record both temperature and mucus all the same.

Every statement shows how certain it is. And where Takt knows nothing, nothing is shown.

How Takt computes

The doctor’s report

One sheet, two readers.

Laid out so your doctor can work with it straight away.

In the app — what you take into the consulting room.

As a PDF — what you send ahead by email.

What you take with you

One sheet instead of a memory exercise. In the consulting room you no longer have to piece together from memory when what happened — and where you share it is your call.

What you send

One file, nothing more. You send it to the practice in advance or take it along printed out — and where it goes is your call.

What you look at together

The report sits finished on your device. In the consulting room you hold it out instead of recounting it from memory — and what you show stays with you.

What your doctor reads

Ranges instead of averages, alongside the clinical reference ranges. It is written in their terms — “bleeding duration”, not “period length” — and says what it rests on.

What we don’t do

Built for you, not about you.

  • No account

    No sign-up, no address, nothing to hand over.

  • Nobody reading along

    Your device does the computing. We never get to see your entries.

  • No data trading

    Nothing about you leaves your device, so nothing can be sold or passed on.

  • No advertising

    No ads, no advertising ID — not on this site either.

  • No pricing tiers

    No Basic, Premium or Pro version. Everything is there from the start.

  • No extra costs

    No add-ons, no unlocking, no surprises.

What you get out of it

You make the entry — Takt does the rest.

  • A quick entry

    Recorded in seconds.

  • A clear calendar

    Every day shows where you stand.

  • A daily widget

    Your cycle day on your home screen.

  • A finished doctor’s report

    One sheet for the consultation.

  • Your data

    Encrypted on your device.

  • An easy switch

    You don’t start over from scratch.

Who Takt is not for

Takt is not for you if you are looking for a contraception app. Takt makes no statement about whether a given day is “safe”, and is expressly not a method of contraception and not a medical device. Takt makes no diagnoses and does not replace medical advice. If you have symptoms or unusual changes, please see a doctor.
