KYL · Know Your Limit
Your bank shows what is there. KYL accounts for payday, bills, targets and real spending. Then it gives you one clear number for today.
Available on iPhone, Android and the web.
The useful difference
How it works
KYL keeps the calculation practical. No bank connection, no account and no spreadsheet to maintain.
Tell KYL your payday, income and regular bills.
Log spending, set money aside or fix KYL against your real bank balance.
See what is safe today and what your daily amount becomes tomorrow.
01 · Before you buy
Enter a one-off purchase or monthly commitment. KYL shows what would be left and how your daily amount would change.
Nothing is saved unless you choose to add it.
02 · Across the month
The Money Calendar brings income, bills and spending into one view. Open any day to see what happened and whether you stayed inside the amount that was safe.
Spending History keeps every logged spend since payday easy to review, edit or remove.
03 · At the checkout
Shopping Basket adds purchases up as you go and shows what would be left today, and from tomorrow, if you paid for it now. Nothing reaches your spending until you choose to add it.
Set a daily target, or choose how much you want left by payday. KYL keeps that stricter goal alongside the normal safe limit, so you do not lose the bigger picture.
When real life gets ahead
If a few things slipped, Fix Balance matches KYL back to what is actually in your bank—without connecting an account—and shows you exactly what it changed and why. Everything else, from Add spend to History, sits one tap from the home screen.
