Receipt is an ad-free, hassle-free, and cost-free tip calculator built to keep life easy.
This app was engineered and designed with a few core principles to incorporate a deeply humanistic view of software interface design.
• DIRECT MANIPULATION •
On the iPhone, there's no more natural form of manipulation than touching what you see. That's why Receipt incorporates a "scrubber" that allows you to touch, drag, and flick numbers to change them. Flick faster to increase the rate at which the numbers change. Of course, you can also use the tried-and-true keyboard for number entry by tapping one of the fields.
• UBIQUITOUS FLEXIBILITY •
If you're using a tip calculator, you may just need the tip and total to write on a receipt. Then again, maybe you already paid $5.00 for a $4.50 drink, and you're wondering if you under tipped. Receipt allows you to change any of the numbers involved in a tip calculation to accommodate any use case. This design also avoids additional "Round Up" or "Round Down" buttons, which create an abstraction that distances users from their intent.
And of course, it never hurts to make things pretty.
Additional features planned for the future include:
– Further control for splitting the bill
– Settings for subtracting sales tax before tipping
– Saving and reviewing previous receipts
