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.
Sanpo

Sanpo is an interval-walking coach. Instead of holding one steady pace, you alternate: a few minutes brisk, then a few minutes easy, repeated for the length of the walk. Sanpo keeps the time and says every change out loud, so you can keep your eyes on the road instead of a screen. HOW BRISK IS BRISK? No straps and no numbers to chase. Brisk means slightly out of breath — you can still say a short sentence, but you could not sing. Easy means you can talk comfortably again. That is the whole technique. WHAT YOU GET FOR FREE • Spoken cues in your language — nine languages, recorded and bundled into the app. Nothing is downloaded and no system voice needs to be installed. • Headphones optional — cues play through the phone speaker if you prefer. • The whole walk at a glance — every brisk and easy stretch on one bar, and what comes next. • A weekly goal you can see — four walking days in any seven keep your streak going, and Sanpo says when the next walk is due. • Milestones and progress — walks, brisk time and streaks, with your history and totals in one place. • Reminders you choose — a daily nudge at your time, a note when your streak needs a walk today, and a Sunday summary of your week. • Set your own fast and slow times — build the walk that suits you instead of taking the default. On iPhone, Sanpo can save each walk to Apple Health as a walking workout — switch it on in Settings. Sanpo reads nothing from Health. SANPO PRO An optional subscription, US$29.99 a year with a 7-day free trial for new subscribers, or US$4.99 a month: • A four-week plan that steps up — start gently, then each week one thing gets a little longer. After that, a rotation of walks keeps you going without getting harder. • A coach that reads how your walks felt — it suggests repeating a week or moving up, and you decide. • More walks for every kind of day — gentle, short and brisk, longer brisk stretches, a long walk. Without Pro, one of them is free each week. • See how your weeks compare — your walks gathered into a trend you can actually read. It renews automatically until you cancel, and you can cancel any time in your Apple ID subscription settings. A free trial becomes the yearly subscription when it ends, unless you cancel before then. PRIVATE BY DESIGN Sanpo has no account, no sign-in and no advertising, and no server holds your walks — your walks, step counts and streak stay on your phone. Since version 1.1 the app sends a few anonymous usage statistics (which screens and features are used, never your steps or your pace) so we know what to improve; switch them off any time in Settings → Privacy. Sanpo is a fitness app. It is not medical advice and not a medical device. If you have a heart or blood pressure condition, joint problems, or have not been active for a while, ask your doctor before you start. Stop right away if you feel chest pain, dizziness or shortness of breath.

Verdict
The clearest difference is in-app purchases: CarlOs at none against Sanpo's 1. CarlOs also leads on iOS requirement (13.4 vs 15.0). Sanpo's advantage is update cadence (fortnightly vs every 5 weeks). On price, ads and device support there is nothing between them.
