### 1/5 — Ne fonctionne pas

*2022-03-08*

C’est dommage , l’.appli est facile a mettre sous iOS, simple à utiliser.. malheureusement, lorsque l’on veut lire les donnés enregistrés, l’application se ferme. Impossible de lires les donnes sauvegarder. Aujourd’hui, 8 Hrs d’enregistrement perdu. Au moment de sauvegarder, l'écran se fige, et ferme l’apps. Produit sans intérêt .
