Thanks for your feedback. You can report any problem to our support team and they will be very glad to help you. ### 1/5 — Acquistata versione a pagamento ma………… *2025-11-05, version 1.7.11* Mi spiace davvero tanto dare feedback negativi. Non è da me. Ma questa volta non posso farne a meno. Ho provato prima e acquistato poi la versione full a pagamento. Bene. Non c’è stata una sola volta che l’app abbia bloccato un solo numero di telefono indesiderato. H verificato tutte le impostazioni e sono tutte corrette, attive ma non c’è verso. Nemmeno quei numeri che risultano già esser segnalati vengono bloccati dall’app. Incredibile. Chiesto il rimborso non per i 9,90 spesi quanto per la totale inutilità dell’applicazione. Mi spiace avrei preferito spendere anche qualcosa in più ma per una app funzionante. Aggiungo inoltre che secondo me la diffiyrispetto al passato è che i numeri spam sono aumentati in modo esagerato e ahimè non credo che nessun sviluppatore sia in grado di fare un’app efficace per questo noioso quanto sgradevole problema dei nostri giorni. Grazie ### 4/5 — Muy muy muy Mala *2025-10-30, version 1.7.11* La instalé esta mañana y la desinstalé esta tarde. No puede ser más mala, me están machacando varios números y no reconoce ninguno. Los copio y busco y solo dice "buscado la primera vez" Peor imposible ### 2/5 — Gibt bessere Alternativen *2025-10-16, version 1.7.11* Bin mittlerweile sehr unzufrieden mit der App, und auch der Einstellung der Entwickler. Das Blockieren funktionierte einige Wochen, dann plötzlich kamen vereinzelt Anrufe mit Score 8 oder 9 durch, trotz Premium. Das ist nicht nur die Kernfunktion der App, sondern auch bezahlt! Wenigstens das muss einwandfrei funktionieren! Und auch die Haltung der Entwickler stört mich. Es wird auf jede Rezension geantwortet, aber auf meine vorherige, die konkretes und konstruktives Feedback gab? Nichts. Und die Usability und Features lassen auch zu wünschen übrig. Warum kann man nur Scores ab 7 oder höher blockieren?? Vielleicht will ich auch Score 5 oder 6 blockieren? Und wenn ich ab Score 4 blockieren möchte, ist das doch meine Sache? Und das andere ist, wieso man keinen Nummernbereich sperren kann. Bin jetzt zu Truecaller gewechselt, und da funktioniert das problemlos. Die Behauptung der Entwickler hier, dass es wegen Limitierungen des Betriebssystems nicht möglich sei, ist eine faule Ausrede. Vielleicht geht das nicht nativ im System, aber offensichtlich lässt sich das auch anderweitig lösen. Und prinzipiell stört mich altbackene UI nicht, aber wenigstens einen Dark Mode könnte man fast 10 Jahre nach Einführung des systemweiten Dark Mode mal unterstützen. Es scheint, das nur noch das absolute Minimum an Arbeit in die App gesteckt wird. Wer noch unschlüssig ist: Probiert lieber erst andere Apps. ### 1/5 — No sirve *2025-08-15, version 1.7.11* No bloquea nada no lo compren ### 5/5 — Nützliche App *2025-08-12, version 1.7.11* Man kann in der Gemeinschaft, sich unterstützen und unbekannte Anrufe bewerten. Damit sehen andere Menschen, ob die Nummer gefährlich oder nervig ist. LG ### 2/5 — Not worth it *2025-08-01* I had this app for a few months and it did not block a single call. Completely set up, turned on and active in phone settings, paid the $15/year subscription. Nothing… Very disappointing. **Developer response:** Hello, A number needs at least 3 reviews and multiple searches before it’s categorized as spam for all users. Therefore, it can happen that some numbers aren’t on the blacklist yet but already show reviews on tellows. ### 2/5 — Tiene que aprender los prefijos *2025-06-24, version 1.7.11* Lo acabo de descargar y empezamos mal 😂desde cuando el prefijo 91 es de valencia ?🤔 ## Frequently asked questions about tellows Caller ID & Blocker ### What does the tellows Caller ID & Blocker app do?
