Tree Notebook is a hierarchical notes manager designed for keeping personal information. Tree Notebook runs on an iOS device (iPhone or iPad). Besides, there is a counterpart for OS Windows which can be synchronized with up to three iOS devices via a local Wi-Fi network. No access to Internet is needed for synchronizing. The data in Tree Notebook is divided in two parts: the public part accessible without password and the encrypted private part which requires password for opening. The data in every part is arranged as a tree-like multilevel hierarchy of folders and notes. Any folder can include notes and other folders, and so fourth. Any item (a note or a folder) can include text of any size. The items can keep attachments like images or other files. The app can represent data in several ways: as a tree, as a list of items (folders and notes) on the current level, as a list of manually selected items ("Favorites"), or the items visited recently ("History"). The contents of an individual item can be viewed or edited. Tree Notebook includes powerful search facilities: simplified or conditional global search, local search inside an item text. The items can be sorted by several criteria: alphabetically, by creation or modification time, and in manually defined order. The item titles can be attributed using a variety of font types, colored flags, graphic icons. Any item can have an Event attribute and serve as an alarm clock or reminder. A calendar feature is available to help managing events. The app is free to use both on iOS devices and desktop PC.

Relanote is а tool that combines both hierarchical and non-hierarchical note-taking. The files and folders method allows you to put some order while the bi-directional links to connect the dots and see the bigger picture. By leveraging the power of both methods, Relanote adapts to your way of thinking. Flexible organization Relanote combines both hierarchical organization (files and folders) and wiki style bi-directional links. You can go even in more details with the additional help of tags. Easy Links & Notes Creation Unlike most apps, in Relanote you can create new notes on the fly without leaving the current note. In Relanote, notes can also be used as mean to link ideas and knowledge. For example, you can have a recipe that includes cheese, beef, and pasta. By linking the ingredients, a note for each will be created that points back to the recipe. Continue doing adding more recipes and at some point by opening the cheese note, you will see all recipes in which it is referenced. Leave organization on autopilot If you are looking to escape the hierarchical organization, no problem! By using bi-directional links, you can forget about sorting your notes in folders and subfolders since all your notes will be connected in a web of knowledge - graph. Graph A visual way to discover hidden connections and see the bigger picture of your whole knowledge base. The Graph offers you a bird's eye view of all your notes and how they are connected. If you are utilizing the bi-directional linking organization instead of the hierarchical, the graph is the tool for making sense of your personal knowledge base. The more connected notes, the harder it becomes to find your way. To solve that, Relanote enables you to filter your notes based on tags you used in them. Full encryption We believe that your knowledge, ideas and research are private and rightfully yours. Nobody but you and the people you shared your note with should be able to have access. To ensure this, all your data is first encrypted on your device and then stored on our secure servers. The process is relatively simple, but incredibly secure - your device -> your notes are encrypted -> stored on our secure servers -> decrypted when you are using Relanote. Share notes with the world Notes, if you need them to be, can be more than a personal thing. You can share your ideas, thoughts, and research directly from Relanote. Sharing a public link to one or more notes is 1 click away. No account is required on the other side to view what you shared with them. The notes are accessible on the web only to those, who have the link. You remain in complete control and can revoke or manage the access at any time. The note you share from Relanote is dynamic - all changes are instantly available to the people you shared it with. Unlike static documents like PDFs, Word Files, and others, Relanote helps you collaborate better.
