Real Estate Investor apps for Rhode Island Real Estate Investors

[Octavian Goncalves]

Hello again Bigger Pockets Community and Real Estate Professionals of Rhode Island, 

I'm looking for the popular effective apps to use if anyone uses apps for the following:

• Mortgage Apps 
• Property Evaluator apps ( for address, projected rents, Income, expenses, financing info, improvement costs, buy & hold,etc )
• Searching for residential and commercial properties apps
• PDF app for signing, pads, deals, contracts, etc
• Apps for landlords to keep track of tenants paying rent, etc 
• Rental property apps that estimate potential monthly, annual cash flow and the ROI (return of investment) for a property
• Rental property Portfolio apps that tracks one's properties in total
• Real Estate contract apps 
• Offer apps

I did look for a couple of apps such as; Easy Mortgage app, shake up law app, etc but wanted to hear from the RI Real estate community of what apps you use or have used currently for efficient usages as an investor of real estate? Please let know through your suggestions, thank you in advance!
