Which Idea Should I Focus On?

HELP! I'm MVP'ing three different products right now, and I need to drill down my focus. All three of these are in Alpha and working, but I don't want to try and promote too many things at once. Which would YOU be most interested in?

Qwklnk - Like bit.ly, but you are buying long-term use of a short URL using domains we own. An example is unoL.ink so you can have unoL.ink/yourname or mynow.info/yourname or betadev.biz/businessname or of course qwklnk.com/yourname

ICOE Vault - An app that lets pre-approved people gain emergency access to your important documents. You send them an invite, they get verify their ID, then if needed they request access and it sends you an email and text, you then have a pre-determined amount of time to approve or decline before it auto-approves.

Zap ISO - ebay in reverse, you post what you are in-search-of (ISO) and people submit sale offers. Only pay when you buy, make extra money, and submit offers without having to first list everything.
