CE QUE KARIN TE RENVOIE chaque dimanche, claude (anthropic) lit ta semaine et te montre tes patterns. ce qui te ressemble vraiment, ce qui te trahit, sans b******t. LE FOCUS tu choisis tes apps piège (tiktok, insta…). karin veille en arrière-plan. quand tu dépasses ton seuil, tu reçois une notification. tu peux alors bloquer ces apps pour la durée que tu veux. avec une vraie friction si tu veux débloquer trop vite. POUR QUI si tu te reconnais plus. si tu te demandes ce que tu fous de tes 20 ans. si tu veux pas te réveiller à 30 ans en mode "qu'est-ce que j'ai foutu". CE QUE KARIN N'EST PAS pas un journal intime. pas un tracker de productivité. pas une app de méditation. c'est un miroir. qui flatte pas. qui juge pas. qui montre. — ABONNEMENT karin · semaine : 4,99€/sem karin · annuel : 39,99€/an (équivalent ~3,33€/mois, économise 85%) pas de free trial. tu décides. — PRIVACY tes notes, ton profil et tes sessions restent sur ton iphone et se synchronisent dans ton iCloud privé — jamais sur les serveurs de karin. tu changes de tel ou tu réinstalles : tout revient. tes vocaux sont transcrits en local, l'audio ne quitte jamais ton téléphone. chaque dimanche, le miroir transmet le texte de tes notes à anthropic (claude) le temps de la génération. ces données ne servent jamais à entraîner un modèle. analytics anonymes via telemetry deck (hash sha-256 du device, aucun identifiant user, aucun tracking inter-apps). — Conditions d'utilisation : karin-web-nine.vercel.app/terms Politique de confidentialité : karin-web-nine.vercel.app/privacy Contact : contact@blockit.fr

Verdict

The call

The clearest difference is monetization model: BlockIt at free with in-app purchases against Karin's subscription. BlockIt also leads on update cadence (every 3 days vs every 6 days) and iOS requirement (16.0 vs 26.5). Karin's advantage is ads (none vs shown) and review sentiment (100% vs 67%). On price, in-app purchases and device support there is nothing between them.
