## What is iStratus Notebook & Planner?

iStratus data manager handles all of your data; your calendar appointments, events, tasks, reminders and To-Do's, passwords and files easily maintained and encrypted in one convenient App.

Unparalleled security is one of the cornerstones of iStratus.  Every item managed by iStratus is capable of being encrypted, and all encryption and decryption takes place on your device.  This means you have the option to never transfer unprotected data to and from your device.

Additional Features:
	Calendar View
	Multiple calendars (Apple, Google, Outlook, etc. in one view)
	Recurring appointments with variable dates and times
	Repeating tasks and To-Do's
	Files, Photos, Notes
	Personalized your way
	Encrypted for your protection (before upload into the cloud)
	Tasking of any item

The iStratus "tasking" feature allows you to make any item an action item.  Simply "task it" with an open or set due date.  Once an item is "tasked," it is treated as a unique task allowing for organization, management, and completion tracking.

Organize all of your tasks by:
	Tagging
	Completion date
	Personalized themes
	Encryption, as needed
	Searchable
	Store them on your iPhone or iPad and in the cloud (Dropbox, Google drive, iCloud)
	Daily roll-up of all open tasks

Create, store and manage these:
	Create a document
	Create a checklist
	Take a few notes
	Take a photo
	Create a voice memo
	Use the included PDF maker to automatically create cropped document scans
	Open an email attachment with iStratus
	Open your existing documents (on device or stored in the cloud)
	Encrypt any item for security
	Track and manage of all of your passwords

The iStratus "Calendar View" is much more than just an appointment calendar.  In addition to your appointments for the day, you will also see tasks, todo’s, and other items that need follow up.

Every day, whether it's a piece of mail, a business card, a new contact, or an e-mail, we have a constant stream of information we need to capture, store, organize, and follow up on later.  iStratus is the only tool you need to manage all of the information in your life.

With iStratus managing your information, your daily tasks become easier.  You capture info as it occurs, organize it however you would like, and "task it" when a follow-up is necessary.  iStratus is there to make organizing your day as simple as possible.

Simply capture it, then "Task it" with iStratus!

### 1/5 — Extremely buggy DON’T recommend

*2025-05-31, version 16.2*

Nothing but locked up features always having to hard close.

### 5/5 — Enjoying App.

*2025-05-08, version 16.2*

Still using this App. Cannot believe its free.

### 1/5 — UI is why only 1 Star

*2025-04-11, version 16.2*

First time user review after enjoying years of TripCase. This app cannot create and save a template that contains folders Notes-Flights-Ground Transport-Hotel-Map-Food-Photos then be able to copy paste that into a block of dates. It can only be done one day at a time and it’s hard based on the UI. Events I don’t want it sync to any calendar I want to create on my own a single event ! More later once I have used it some more.
I don’t need nor want my entire calendar in this app. Reducing this review from 2 stars down to 1 star and there is no undo feature.

### 4/5 — Nice

*2025-02-15, version 16.2*

It would be great if we could share files and calendar with other stratus users.

Also, if for some reason my app got deleted I lose all my saved data. I can’t put effort on something I might lose forever.

I really hope you work on my suggestion. And would be great to get a reply from the developer

### 5/5 — Pro

*2025-01-02, version 16.2*

Great design this app has

### 5/5 — It’s very useful

*2024-10-04, version 16.2*

It has a lot of handy tools I need to have on such an app and lets me organize and customize however works best for me. I first thought it was going to be too busy and be too complicated for me. But really it isn’t. I stuck with it and after a couple of days using it I’ve become familiar with it. Now I think I would miss it if I didn’t have it anymore! I really like this app a lot. I would recommend it to others who need to have their to do lists and calendar events written down in front of them to see in order to keep their lives on track like I do. The best thing about it too is I haven’t paid anything for it. I’ve paid for apps that do similar things but weren’t as easy or as effective at keeping my life in order so I don’t get behind. Thank you for making this app a reality. I almost feel like you made this app specifically for me. It fits me very well.  I don’t have anything negative to say about it. I’m very happy with it.

### 4/5 — Review

*2024-09-06, version 16.2*

This is really a good app for a calendar .   I like the data it provides and the organization I can keep up with .   I would recommend it to anyone .  However , since I changed phones , I am trying to get the original app pro which I purchased some years ago and I am having a few issues trying to get it to connect  the  istratus with the Google .   
If you a person who loves organization , prefer some attachments , reminders, planning, and simply like colors etc ( too much too list )  .  Try it .

### 5/5 — Excellent app

*2024-09-04, version 16.2*

Excellent app and excellent way to keep things organized and stay on top of your daily tasks whether it’s critical or non-critical

### 5/5 — extactly what ive been looking for

*2024-08-20, version 16.2*

you will have a hard time that offers the personal system iStratus offers

### 5/5 — Istratus

*2024-07-14, version 16.2*

The best app installed on my iPhone. With this App, I got my life back. I’m in control of everything I need to live happily and stress free. It’s fully customizable to fit your individual need. Once you get the hang of it, you’ll never let it go.
