### 5/5 — Thank You!

*2024-04-19*

Thank You for putting this together. It was very helpful, as I have done it the old fashioned way. I snapped a pic of my glove box tag and just bounded back and forth between apps to fill in the code spaces. It was pretty interesting just doing a few at a time and decoding them, and seeing what the actual build was. Thanks Again!

### 1/5 — Meh

*2022-05-23*

Would be better if it didn’t delete half the **** I spent time putting in once I get to a certain point.

### 5/5 — Very helpful

*2022-05-18*

This app is awesome for figuring out square body Chevy rpo codes, just remember to tap on the result if it’s confusing as some codes were used for multiple options.

### 3/5 — Not bad

*2022-03-14*

I appreciate the effort put into this app, but entering RPO codes one-at-a-time is frustrating. I noticed a bug when scrolling down to enter more that somehow I cleared 3 full rows of codes. Suggest at minimum a large text field where users can copy/paste a full list of whitespace delimited codes, best feature upgrade would be to use iPhone’s OCR/“Vision” framework to automatically enter codes.
