Hi @rali02 Thanks for stopping by the community! To help answer your questions, 

• Our forms are made to be compatible on most devices and browsers. You can view a full list of the devices and browsers we support here. 
• Our forms must be online, connected to internet, to collect data. 
• We hope so! Do you mind clarifying what you’re looking for in the form in regards to user-friendliness? That’ll help me answer this better. 
• You can export the data through a CSV file in the Results panel of your form. We also have plenty of integrations here to export your data to. 

I hope this helps! Let me know if you have any other questions.
