Krepp lends 100 to 1,000 manats to a bank card, and the collateral is your smartphone. It is pledged digitally by its IMEI — you keep using it — and it gets blocked only if the loan isn’t repaid. I designed the app: the application from IMEI to money, identity checks, the home screen that tracks the debt, and both themes.
This phone replays the home screen’s two states from the design: days left, then the warning. The amount is illustrative.
Krepp is live in the App Store. I don’t have its loan or conversion data, so this page shows the decisions, not results.
From IMEI to money, one decision per screen
The application is a straight line with no branches to get lost in: the phone, the amount, the ID, the face, the bureau check, the offer, the card. Every screen asks one thing and says why.








Signing a loan with your face
There is no office to sign in. The agreement and the rules are a readable document with a table of contents, and the signature is a face photo taken against the ID. A refusal says what it is based on.




One ring: what you owe and how long you have
After the money arrives the only question is “how much, until when”. The home screen answers it with a single ring: the amount in the middle, the days left around it. When the term runs out the ring turns red and the screen says the honest consequence — the phone will be blocked — with the pay button right under it.





Light and dark, the same meaning
Every screen exists in both themes — the application, the check, the debt. In the dark one the rings become a glow, but the colours keep their job: calm while there is time, red when there isn’t.
Everything else stays out of the way
Profile, cards, history, rules and support live behind one menu of large tiles. A new user without a debt gets a home screen that points to the two ways to get money instead of an empty ring.




Some application screens carry the “E-Borc” mark — the name of the loan product inside the app; Krepp is the app around it.
A loan you can read at a glance
A lending app for Azerbaijan: apply with the phone as collateral, verify without a branch, and always know what you owe and how long you have — in light and dark.
