Poubelle ### 1/5 — Payant *2025-12-23* Mauvaise surprise, payant ! On enregistre et on doit payer alors même que des pubs soient mises…. Techniques sournoises dommage ### 2/5 — Sonomètre *2025-08-09, version 3.37* -Pas de mode d’emploi, pour moi, c’est rédhibitoire. -il faudrait que ces commandes soient très claires et faciles à trouver: enregistrement du son, arrêt, écoute , sauvegarde du fichier. -Pour créer un compte, il faut accepter les Cgu? qui sont toutes écrites en anglais, pas de choix de langues. - la barre de son par contre, est très bien, très lisible et explicative. C’est le seul point positif que je trouve. - je trouve la pub, agressive et longue, plus longue que l’enregistrement qu’on fait… Ils proposent un abonnement que je trouve trop cher pour mon emploi peu fréquent de l’application. ### 3/5 — 有料なら *2025-05-17* 使う度にしばらく消せない前面広告を見させられてもイライラしない観音様の様な人なら無料でも使えるかな？ 私は同じようなアプリで広告控えめなのあったからそっち使います。 ### 1/5 — Scarsa *2024-11-28, version 3.30* Misurazioni non vere ### 2/5 — No funcionó *2024-09-21, version 3.26* Eso, quise medir el sonido de una planta eléctrica, mis oídos estallados pero la app marca -67 decibeles ### 2/5 — 広告が多い *2024-08-08* 測定のたびに広告が出る ### 2/5 — Uccisa dalla troppa pubblicità *2024-07-30, version 3.22* Una buona app Uccisa dalla troppa pubblicità, ### 1/5 — Só anúncios agora. *2024-07-16* Era ótimo.
