כינור לב vs Perach

כינור לב היא אפליקציית ביופידבק שמנגנת את המוזיקה האהובה שלך בסנכרון לקצב הלב - המטרונם זה הלב שלך, מה שיוצר הרפיה עמוקה,הורדת הסטרס, סנכרון ואיזון המערכות החשובות בגוף. זאת בנוסף לאיזון רגשי, שלווה והתחברות אל עצמכם. האפליקציה פותחה על ידי ד"ר ליפו בהשראת נגינתו של דוד המלך.

Perach works out your dates and reminds you: hefsek taharah, seven clean days, mikvah night — following your custom, at the solar times of wherever you are. YOUR DATA STAYS ON YOUR PHONE Your journal — dates, checks, observations — stays on your device, encrypted and protected by your passcode. We never receive it, so we cannot read it. No ads, no trackers, nothing sold. PERACH GIVES NO PSAK For a doubt, a colour, an unusual situation, the app never answers in a rav's place: it takes you to one. You can write to a rav whose identity has been verified by hand. Your messages are end-to-end encrypted. To write, you identify yourself once (Apple or Google account): your rav does not see your name unless you choose to give your first name, and these details stay sealed; we only access them in the event of a report, abuse or a legal obligation. DISCREET, BECAUSE IT IS PRIVATE You can disguise the text of your reminders on the lock screen, and lock the app with Face ID. On Shabbat and festivals everything falls silent: whatever was due to ring during is announced before it comes in. ALSO INSIDE • Over 2,000 mikvaot worldwide, with map, hours and directions • A travel mode that recalculates your milestones in your destination's time zone • A calendar that shows where you stand at a glance • A week sheet you can print or send to your rav • 29 languages, including Hebrew and Yiddish FREE No subscription, no in-app purchases, no advertising. Perach is a calculation and reminder aid. The dates it shows are estimates based on the custom you chose; they are neither a halachic ruling nor medical advice. Any question of doubt belongs to your rav or a yoetzet halacha.
