Vielleicht eine Stufe im Lifestyle zurück und dafür seine Zusagen die man sich bezahlen lassen hat halten. ### 1/5 — Pro Version gekauft und jetzt beraubt worden *2024-08-14, version 5.1* Ich habe die Lifetime Pro Version gekauft und wurde offenbar per automatischem Update alle Pro Funktionen entfernt. Das ist Betrug!!! Erinnert an den Diesel Skandal. ### 1/5 — Unverschämt! *2024-03-16, version 5.0* Ganz großes Kino! Ich habe mir die Profi Version gekauft, um die Profi Funktionen zu verwenden. Der Hinweis nicht upzudaten ist ein Witz, da dies bei iOS automatisch passiert. Somit bin ich schön zur Basis Version „geupdated“ worden und werde nochmals zur Kasse gebeten. Eine dreiste Masche und zeigt wie wichtig Bestandskunden sind. Nie wieder! Deinstalliert und tschüss! ### 5/5 — Beste Finanz-App *2024-03-16* Alle die professionell Beraten wollen, kommen an dieser App nicht vorbei!
