Simple, on purpose
Most budget apps want your bank login, an account and an hour of setup. Purple Brock™ needs two minutes: when you're paid, and your bills.
Stays on your phone
Your money stays on your iPhone. No account, no bank login, nothing sent to us or anyone.
Two minutes to start
Add your payday and your bills. That's it — no categories to sort, no spreadsheets.
One calm screen
Everything you need, nothing you don't.
