## What is Purr Diem?

Purr Diem was born from a simple need: As a business traveler receiving daily per diem allowances, I wanted to track my spending throughout the day—not just to maximize savings from my trips, but to budget strategically. Save on breakfast and lunch? That means I can enjoy a nice dinner at the end of the day. After years of not monitoring my per diem expenses, and losing receipts, I built Purr Diem to be the tool I wish I'd had on every business trip.

Purr Diem helps you stay aware of your per diem balance in real-time, so you can make smart spending decisions and keep more of what you're reimbursed. Whether you're traveling for business, attending conferences, or managing event budgets, Purr Diem gives you the clarity and control you need to track expenses, stay under budget, and make the most of every trip.

• Lifetime: $9.99 one-time payment.  Completely removes all ads.  I removed all subscriptions, because no one likes subscriptions.  The lifetime purchase is a way to support this Indie developer.  Thank you for your support!
