7Pass 
what differences between free and paid version? I installed free version actually, but I’m unable to perform searches. is there any limitation?
thanks
I have the same question, what are the differences between the apps?
In Free and Trial version, 7Pass will display a toast message (just like when you receive an SMS) for the first 5 times 7Pass is started. The toast will not be displayed ever again, unless you remove 7Pass and install it again.
Paid version will never has the toast.
Other than the toast, Free, Trial and Paid all works the same way, no limitation whatsoever.
Kudos to you for your work and how you approached it: source code available, free version not being limited, support and answers. I just purchased the paid version just to say Thank you for all of these.
Hallo,
ich habe 7Pass gekauft. Angezeigt wird weiter die Demo-Version. Auch habe ich keine Möglichkeit gefunden das Demo-Passwort zu wechseln.
Wenn Sie mir bitte mitteilen, was ich tun soll.
Gruß
