Your alarm rings.
Keep your basal thermometer beside you. Your alarm brings the measurement to the start of your morning, before you get out of bed.

HOW THE ALARM IS DESIGNED TO WORK
Your alarm.
Your reading. Saved.
You bring the intention.
We’re here to help with the routine.
02
Measure. Take a photo.
Take your basal temperature while still in bed. Wait for the thermometer to finish, then photograph its display. Basalarm reads the number for you to check.
03
Confirm. Finish the alarm.
Confirm the temperature to complete the planned alarm routine and save your reading. Build a history you can review alongside your cycle dates.
When you’re trying to conceive, this isn’t just another number. Basalarm is being built to help you remember your waking temperature and keep a clear history of your cycle.
Planned in-app flow. iOS system alarm controls remain available; photo completion is subject to beta testing.
TEMPERATURE TRACKING WHEN YOU’RE TTC
Understand the shift.
Know your pattern.
Your basal body temperature can rise slightly after ovulation. Recording it consistently can help you recognize that shift and understand your cycle patterns over time.
Basalarm focuses on the part that comes first: remembering to measure on waking, before getting up. It is being designed to keep those readings together as you try to conceive.
Read the guidance from Mayo ClinicWhat the pattern can tell you.
A temperature rise usually follows ovulation; the most fertile days come before that rise. BBT alone cannot pinpoint ovulation or reliably predict your fertile window in advance. Basalarm does not guarantee pregnancy. Learn more at ACOG.

A FEW THINGS TO KNOW
Good questions.
Clear answers.
Can I download Basalarm now?
Not publicly yet. A private prototype is being tested, and we’re preparing the first iOS beta. Join the waitlist for launch and testing updates. There’s no payment or commitment to buy.
Will a photo be the only way to stop the alarm?
That’s the experience we’re exploring: the in-app morning routine finishes after you photograph and confirm a reading. iOS retains system alarm controls, so we can’t promise an alarm that is impossible to dismiss. The beta will test what works reliably, with a way to skip when you need to.
What if I wake up before my alarm?
Measure when you actually wake up, before getting out of bed, eating, or drinking. You don’t need to wake earlier just to use Basalarm. Consistent timing and adequate sleep matter; interrupted sleep can affect a reading. We plan to support early check-ins and timing notes.
Will Basalarm tell me exactly when I ovulate?
No. A sustained basal temperature rise can help you recognize that ovulation likely already happened. It cannot pinpoint the exact moment or reliably give advance notice of your fertile window on its own. Basalarm is being built to support recording while trying to conceive; it has not been shown to increase conception rates.
Can I use Basalarm as birth control?
No. Basalarm is being designed for recording and cycle awareness, not contraception, diagnosis, or guaranteed ovulation prediction. Basal temperature mainly reflects changes after ovulation. If you need fertility or contraception guidance, speak with a qualified clinician.
Do I need a special thermometer?
Choose a thermometer intended for basal temperature tracking, with two-decimal readings and documented accuracy. A hundredth-degree display describes resolution, not necessarily accuracy. Follow its instructions and measure consistently with the same device and method.
What information does the waitlist collect?
Just your email, signup time, consent record, and a basic signup source. This website does not ask for temperatures, photos, or cycle information. You can remove your signup with the private link shown after joining. Read the privacy page for details.
