PRESS appgefahren.de (Germany): „Brim: Neuer Wasser-Tracker passt sich täglich an Wetter, Schritte und Schlaf an." iGeneration (France): « Brim, une app élégante pour mieux suivre son hydratation avec des objectifs intelligents. » AppBank (Japan): 「天気・運動・睡眠に連動! スマート水分補給アプリ『Brim』がiOSに登場」 ELECTROLYTES (PRO) Water isn't the whole story. When you sweat from heat, training, sauna or low-carb, you lose sodium, potassium and magnesium too. Brim estimates your electrolyte need from the same workout and weather data that drives your water goal, lets you log sources in a tap, and syncs with Apple Health. For the active, sauna and keto crowd who replace electrolytes — not cut them. Not medical advice.
