About this app

Bananza Companion is a map and checklist app for Donkey Kong Bananza. It shows where the Banandium Gems and fossils are hidden and remembers which ones you already have, so you know where to dig next.

MAPS OF EVERY LAYER
30 maps for Ingot Isle, the layers with their sublayers, The Divide, The Junction and the Planet Core, with more than 1,500 markers: Banandium Gems, fossils, checkpoints, battles, courses, Shifty Smash challenges, chip exchanges, style and stuff shops, and the transitions between the layers.

Tap a gem or fossil marker to see a picture of the spot and a short tip, and tick it off. The filter shows everything, only what you still need or only what you are done with, and you can add your own markers.

BANANDIUM GEMS AND FOSSILS
All 777 Banandium Gems and 696 fossils in 29 kinds, sorted by layer and numbered. Almost every entry has a picture of where to find it. Tick a gem off in the list and it is marked on the map as well, and the other way round. The statistics show how many gems and fossils you have found so far.

NOTES, SEARCH AND AI ASSISTANT
Notes with folders, tags and sketches keep your own plans in the app. On a tablet or an unfolded iPhone Duo they open right next to the map. A search across the whole app finds any gem, fossil or place. The AI assistant answers questions about the game; it needs an internet connection and becomes available after an in-app purchase.

GOOD TO KNOW
Most maps come with the app, the maps of the later layers are downloaded once inside the app. After that the maps and lists work offline. Your progress is saved on your device. A backup file or a Sync-ID takes it to another phone or tablet, Android or iPhone. Press and hold the app icon to jump to your checklists or the last map spot you opened.

The app is made for iPhone, iPad and the folding iPhone Duo as well as Android phones and tablets. It is available in 15 languages. The names of the gems, fossils and layers follow the official translations of the game; the short location tips are in English.

Bananza Companion is free with ads. A one-time purchase removes the ads, and the "Fully unlock all our apps" subscription removes them in all of our companion apps and unlocks their content.
