Software that earns its place in your day.
Built4U Apps builds focused, privacy-respecting products — for mobile and the web — that do one job exceptionally well. No clutter, no dark patterns, no selling your data.
What we've built
Each app does one job well — and respects your privacy while doing it.
LendBook
A private app to record and track the loans you've personally given or taken — borrowers, interest, EMIs, due dates, payments, reports and statements. It never lends money or moves funds.
- Every loan type, accurate to the rupee
- Reminders, statements & analytics
- 21 currencies · 16 countries · 10 languages
KinNest
A private app to record everything you own — property, gold, insurance, accounts — and make it reachable by your family if something ever happens to you. A map, not a vault.
- Write down what you own and where it is
- Checks that you're okay, then hands over carefully
- No passwords, no documents — nothing to steal
More apps on the way
We're building outward from LendBook and KinNest — more focused tools for everyday money, records and life admin.

Standards we don't compromise
The principles behind everything we ship.
Privacy first
No ads, no profiling, no data sale. Your data is encrypted and yours — export or delete it any time.
Correct by design
Especially with money. Every figure is derived from one auditable source, so the numbers always agree.
Focused & global
One job done well, working across currencies, countries and languages — for real people, everywhere.
Built to last
No dark patterns, no nickel-and-diming. We build the software we'd want to use ourselves.
Useful software should be simple, honest, and private — built for the people who use it, not for advertisers.
We're a small, independent studio sweating the details most apps skip: correctness, clarity, and respect for your data.
An independent studio
Built4U Apps is an independent studio building practical software — for mobile and the web — that people can rely on. We believe the best software is quiet, dependable, and on your side.
We started with LendBook, KinNest is in early access — and we're building outward from there.
Let's talk
Questions, support, partnerships, or press — we'd love to hear from you.
