Best free mind-mapping app out there

I have tried quite a few apps over the last few weeks and they have come up short for a variety of different reasons, mostly due to no support for linking between nodes. This app definitely supports that feature on the free tier with a few added goodies, the best of which is Touch ID. As an entrepreneur, I like the peace of mind knowing that my ideas are protected.

My only complaint with this app is the very high cost of the premium subscription and only selling it in six or twelve month plans. Selling it in 6 or 12 month plans puts a big hurdle up for people wanting to assess whether premium features are worth a long term subscription. I would recommend offering a one month subscription to other prospective pro consumers. All in all, this is definitely the most feature rich one I have come across. I encourage you guys to take a look.
