Version History Fixes from your feedback:

• Checklists stay in your language — if you switch between English and Spanish partway through a Pre-Trip or Load/Unload checklist, the items, the saved record and its PDF now follow the app's language, and the details you already typed are kept.

• Checklist dates, on screen and in PDFs, now follow the app's language instead of your phone's. 40.3 Sep 14 Fixes from your feedback:

• Emergency Contacts — tapping the call button now opens your phone app.

• Load/Unload Checklist — add the load, location and driver details, then save the finished checklist as a record you can open again later.

• Placarding PDF — now titled "Field Tools Report", and it carries the full breakdown and the potential segregation issues you saw on screen.

• Flash cards — you now get the number of cards you asked for. Setting 10 used to give you 8.

• Mock test — the question count now reflects what the free version actually holds, instead of showing totals like "200/30".

• ERG Lookup — guides 121 and 167, which the 2024 guidebook retired, no longer appear as blank entries, and the guide count now reads correctly as 62.

• Help — no longer describes PDF exports the app doesn't offer. 40.2 Sep 11 New in this version:

• A brand new app icon.
• ERG Lookup now sits in Quick Reference, right beside ERG Basics — the fastest route to a guide number. It's still on the Field Tools screen too, so the path you already know keeps working.
• Clearer naming: the reference category is now "ERG Basics" and the searchable guidebook is "ERG Lookup", each with its own icon so they're easy to tell apart.
• Spanish wording refreshed across the ERG screens and in-app help. 40.1 Aug 6 Now in Spanish! ¡Ahora en Español!

• Full Spanish translation of the entire app — practice questions, explanations, field tools, and Quick Reference. Switch between English and Spanish anytime in Settings.
• Expanded question bank — 200+ practice questions across Hazardous Materials, Tank Vehicles, and Doubles & Triples.
• Refreshed ERG 2024 reference and field tools.
• Stability improvements and bug fixes.
