Such fast deletion makes this a useless app. ### 1/5 — App Erased All Data *2024-02-12* There’s cool things about the app, except it erased all my data after a few hours. Also beer comes in 12 oz, it was weird to choose between 10 and 13. ### 2/5 — Simple Design but Needs Work *2024-02-10* Easy to use drink tracker but BAC is inaccurate because it doesn’t take into account basic metabolism. BAC kept going up and up, despite there being hours in between. Also the app erased my data after like 4 hours. ### 1/5 — Terrible *2023-12-31* Hesitant to give it more than 1 star because I don’t trust it at all. Lost all my progress. The graph is not to scale, I don’t quite understand it. Does not fit Australian drinks or standard drink sizes. A bit of improvement and it could be useful. ## Frequently asked questions about Alcohol BAC Calculator ### Does Alcohol BAC Calculator have ads? Yes, Alcohol BAC Calculator contains advertisements.
