Ensuite seulement on d\u00e9cide s\u2019il faut corriger, refondre ou reconstruire.<\/p>\n<p>Une app mobile peut sembler \u201cpresque termin\u00e9e\u201d alors que ses risques sont invisibles : comptes store mal transmis, d\u00e9pendances obsol\u00e8tes, backend fragile, absence de tracking, dette UX, notifications cass\u00e9es, crashes non suivis ou code difficile \u00e0 reprendre.<\/p>\n<h2>Ce qu\u2019il faut auditer avant de relancer<\/h2>\n<ul>\n<li>acc\u00e8s App Store \/ Google Play et propri\u00e9t\u00e9 des comptes ;<\/li>\n<li>technologie : Flutter, React Native, iOS, Android ou hybride ;<\/li>\n<li>qualit\u00e9 du code et d\u00e9pendances ;<\/li>\n<li>API, backend, base de donn\u00e9es et authentification ;<\/li>\n<li>analytics, crashes, logs et retours utilisateurs ;<\/li>\n<li>parcours critiques : inscription, paiement, contenu, notifications.<\/li>\n<\/ul>\n<p><strong>Bloc extractible :<\/strong> la reprise d\u2019une application mobile doit produire un verdict clair : corriger, stabiliser, refondre partiellement ou reconstruire.
