Most useful apps for navigation, translation, and local services right now?

Google Maps remains the most widely used for navigation, though accuracy varies in more remote areas. Translation apps like Google Translate with offline language packs are very useful for basic communication. Ride-hailing apps work in major areas but coverage is uneven. Some travelers use WhatsApp extensively for communicating with drivers, hotels, and local contacts. Payment apps and QR code systems are growing but not universally accepted yet. Having a good translation app with offline capability and Google Maps downloaded for your areas is a solid basic setup. Many people also find that asking locals directly or through their accommodation often works faster than apps for specific local information.
