This is why I am rating it so high. It’s very helpful and it shows how great of a community we have for the game ### 3/5 — Decent *2023-11-15* It has a lot of information. But it is outdated. Missing a lot of recent cooking, alchemy, and processing recipes. It will be perfect if it were updated. ### 1/5 — Way outdated and Boss Notifications don’t work. *2023-09-26* The boss timer is really what I wanted this for, but it has never, not even once notified me for any boss. I have all options for bosses on as well as allowed the app to send notifications. Don’t waste your time on this app. Aside from that, much of the info is outdated, especially the horse calculator. Waste of time. Wish there was another option with all the features… but obviously one that actually worked. ### 5/5 — Fantastic! *2023-07-26, version 8.0.3* Used this app for a very long time, absolutely amazing companion app. ### 3/5 — Update Please *2023-05-06* Needs to be updated ### 5/5 — Very convenient *2021-11-22* I’ve been using this for the better part of a year. I have a boss alarm set on my phone for all the spawn times and this app sends me a notification and identifies each boss at a glance. I don’t even have to mess with my pc browser and im ready to log into the appropriate boss alt. ### 5/5 — 🌟 *2021-08-15* Thank you for making this awesome app. perfect application for all BDO players ### 3/5 — Boss timer update *2021-03-06* Can we get boss timer update? The boss timer changed ### 1/5 — Needs Revision *2021-01-24* It’s not up to date ### 5/5 — Amazing *2020-11-01* It’s a great app, very informative, and useful. I have only had it for the span for 2 minutes and it’s already 100% times better than BDO+. I would definitely recommend this to anyone especially if you are one who grinds bosses, or if you need information when it comes to crafting certain materials. ## Frequently asked questions about Companion for BDO ### What is Companion for BDO?
