how it works

two sides of your life.
finally connected.

xaelr reads your physical state and your financial behaviour simultaneously. and shows you the relationship between them.

what xaelr tracks

three health signals.
one financial picture.
one connection.

no other app has all four data streams simultaneously. that combination is what makes the intelligence possible.

๐ŸŒ™
sleep
apple health ยท apple watch ยท garmin ยท oura

sleep duration and quality compared against your personal average. when sleep drops below your usual, the prediction engine activates.

โ†’ predicts spend risk
๐Ÿ’“
recovery (HRV)
apple watch ยท garmin ยท oura ยท whoop

heart rate variability is a real-time window into your stress state. low HRV overnight signals elevated cortisol. which impairs financial decision-making.

โ†’ stress signal
๐Ÿ˜
mood
daily check-in ยท post-spend tag

a quick morning check-in captures your emotional baseline before the day's financial decisions happen. over time this builds your mood-spend pattern.

โ†’ mood-spend correlation
โ—Ž
spending
manual logging ยท csv import ยท open banking

transactions logged manually or imported. categorised automatically. compared against your weekly budget. the financial output that the health signals predict.

the journey

it gets smarter
the longer you use it.

xaelr builds a model of you over time. week one is just the beginning.

1
day one

the spending trigger.

during onboarding, xaelr asks one question: "when do you usually overspend?" you select your trigger. stressed, tired, low mood, celebrating, or no idea. from that moment xaelr watches for that specific physiological signal in your health data.

"rough night. you said you overspend when you're tired. worth knowing today."
2
week one

the picture forms.

the picture screen shows sleep, mood, and spending on the same axis for the same days. by day three the pattern is often already visible. the days with short sleep bars, amber mood dots, and higher spend numbers align. you can see it before xaelr names it.

3
week three

the xaelr index validates.

after three weeks of combined health and financial data, the xaelr index calculates the correlation specific to you. it assigns a confidence percentage. 60% means the signal is emerging, 85% means it's confirmed, 95% means it's definitive. not a generic insight. a pattern in your own data.

"your worst spending weeks follow your worst sleep. confidence: 78%. wednesday is consistently the highest risk day."
4
month one onwards

the prediction fires.

once a pattern is validated, the prediction engine activates. overnight health data is read before you open the app. if sleep dropped or HRV dipped. and your pattern says that predicts higher spending. a notification fires before your day begins.

"rough night. last time this happened you spent ยฃ340 in a week. your budget is ยฃ280. watch wednesday. that's usually when it happens."
5
month two+

the monthly portrait.

on the first of each month xaelr writes a personal synthesis of the previous month. what your health data showed, what your financial data showed, what the connection looked like. gets richer and more accurate with every passing month.

โˆž
ongoing

it gets more accurate over time.

pattern confidence grows from signal to confirmed to definitive. the monthly portrait gets richer. the prediction engine gets more precise. a user with six months of xaelr data has something genuinely irreplaceable. a model of themselves that no other product can build.

getting started

up and running
in five minutes.

step 01

download and set up your number

enter your monthly income and a rough estimate of your outgoings. xaelr calculates your weekly spending headroom number immediately. takes two minutes. rough is fine. it gets more accurate as you add details.

โšก first number in under 2 minutes
step 02

connect apple health

one permission dialogue. xaelr reads sleep, steps, HRV, and mindful minutes from apple health. or from your connected wearable (apple watch, garmin, oura, whoop). read-only access. nothing is written back.

๐ŸŒ™ health data flowing in minutes
step 03

check in every morning

the health screen opens in the morning. one tap mood check-in. five options, takes two seconds. this is xaelr's most important daily data point. it captures your emotional baseline before the day's financial decisions happen.

๐Ÿ˜ two seconds. every morning.
step 04

log what you spend

tap the + button and log transactions as you go. or import a bank statement CSV. manual logging or imports both work. the more complete the data, the sharper the intelligence.

โ—Ž open banking coming soon
step 05

wait for the moment

after three weeks the xaelr index starts to confirm your personal pattern. after a month the prediction engine fires. when the prediction is confirmed. when xaelr told you on monday and wednesday played out exactly as it said. that's the moment.

โšก pattern confirmed. your picture.
questions

things people ask.

does xaelr need open banking? +
you can log transactions manually using the + button, or import a CSV from your bank. the intelligence works with manual data; it just gets sharper with more of it. open banking is coming soon.
what wearables does xaelr support? +
anything that writes to apple health. apple watch, garmin, oura ring, fitbit, and others. if your wearable syncs to apple health, xaelr can read it. more direct integrations are coming soon.
how long until the xaelr index has something meaningful? +
three weeks minimum. the index needs enough combined health and financial data to calculate a correlation with statistical confidence. at week three you'll see the first signal (60% confidence). by week six most users have a confirmed pattern (75%+). by month three it's usually definitive.
what does xaelr do with my data? +
your data is yours. xaelr processes health and financial data to build your personal picture. it is never sold, never used for advertising, never shared with third parties. the business model is subscription. you are not the product. ever. you can see everything xaelr knows about you in the memory view screen and delete it at any time.
will xaelr tell me what to do? +
no. xaelr observes, shares, and stops. it will show you patterns. it will make predictions. it will confirm when predictions prove correct. it will never tell you to cut back on takeaways, try mindfulness, or make a budget. the decisions are yours. always.
android. when? +
xaelr launches on iOS first because apple health is central to the product and has better health data quality and wearable coverage. android is coming soon.

questions people ask

what xaelr is, and what it is not.

xaelr is built around pattern awareness, not pressure. It helps you notice what appears to sit around your spending, while staying clear about its limits.

What is xaelr?

xaelr is an early-access iOS app that helps people notice patterns between spending behaviour, mood, sleep, stress and daily habits.

Is xaelr a budgeting app?

xaelr is not a traditional budgeting app. It focuses on helping users understand the context around their spending, not just tracking what was spent.

Does xaelr give financial advice?

No. xaelr does not provide financial advice. It helps users notice patterns in their own data so they can understand their habits more clearly.

Does xaelr give medical advice?

No. xaelr does not provide medical advice, diagnosis or treatment. It can help users observe patterns involving sleep, mood, stress and spending, but it is not a medical tool.

What data does xaelr use?

xaelr is designed to work with signals the user chooses to connect or log, such as spending, mood, sleep, stress, energy and small daily habits.

What does xaelr mean by patterns?

Patterns are observations in a user's own data, such as spending appearing near low sleep, stressful weeks or changes in routine. xaelr does not claim these are universal facts or guaranteed causes.

How does xaelr protect trust?

xaelr is being built around consent, clarity and control. The aim is to help users understand their own patterns without shame, judgement or unnecessary pressure.
