Le calcium est essentiel à la santé osseuse. Il a un rôle dans la formation et la solidité des os tout au long de la vie. Un apport insuffisant en calcium peut fragiliser les os et fait partie des principaux facteurs de risque favorisant l’ostéoporose, une maladie caractérisée par une diminution de la masse osseuse. L’ostéoporose augmente le risque de fractures dont les conséquences peuvent être très lourdes au quotidien. Pour vous aider à préserver la santé de vos os, le laboratoire Arrow a développé l’application « CarlOs ». Elle vous permet, selon votre profil, de connaître vos besoins journaliers en calcium et de calculer vos apports alimentaires calciques au quotidien, de manière simple et rapide. Ces informations sont purement indicatives et ne constituent en rien un conseil médical, ni un diagnostic. L’application n’est pas destinée à se substituer aux conseils ou au suivi médical des professionnels de santé. L’application donne accès à l’évolution de vos apports en calcium. De plus, des fiches pratiques vous informant sur la santé osseuse (l’importance du calcium et de la vitamine D, l’ostéoporose, ses facteurs de risques etc…) sont mises à votre disposition. Arrow Génériques n’est aucunement responsable de la qualité, de la complétude ou de la véracité des données saisies par l’utilisateur et n’est en aucun cas en mesure d’apprécier l’état de santé de l’utilisateur qui demeure seul responsable de toute décision ou action mise en œuvre à partir des informations saisies dans l’application et des résultats donnés par elle.

Read full description

DaySense is a private daily tracker for building a record around the parts of your day you actually want to review. Choose a profile, shape your daily check-in, and log mood, energy, sleep, stress, medication, caffeine, journal notes, appointments, and optional context in one calm flow. Every field is optional, so your record can stay focused. Profiles help tailor the labels, context prompts, review boards, and resources around different kinds of day-to-day tracking: The General profile includes broad mood and energy context, daily strain tags, reset tags, and general wellbeing resources. The Bipolar profile includes mood, energy, sleep, rhythm context, activation tags, lower mood or pullback tags, and a rhythm review board. The Anxiety profile includes mood and energy context, worry and stress tags, day-balance tags, and a pressure review board. The ADHD profile includes mood and energy context, attention-load tags, task-friction tags, regulation context, and a focus review board. The Autism profile includes mood and energy context, sensory-load tags, predictability and change tags, social-effort context, and autism-focused resources. The Sleep Sensitive profile includes mood and energy context, sleep timing, sleep disruptor tags, routine stability, rest quality, and a sleep path review board. Review what you saved over time with charts, metric cards, selected-day detail, profile-aware review boards, and target progress. DaySense reflects logged values and saved context without diagnosis, prediction, medical advice, or automated monitoring. DaySense stores your record locally on your iPhone in the current build. No account is required. Export your record, import it on another device, or delete local data from Settings. Premium includes longer review, Apple Health imports, external imports (from other tracking apps), extra trackers, extra profile contexts, Review Packs, and advanced record tools during an eligible introductory trial or active subscription. Free daily logging and recent review remain available. DaySense is for private tracking and record review only. It is not medical advice, emergency support, diagnosis, treatment, or a replacement for professional care.
