Our Review:

When I downloaded and opened To-Do Calendar Planner (also known as isoTimer), I really was impressed at how quickly it loaded and how the app synchronized with Google calendar by itself without me having to anything. As Android devices are connected to a Google account to enable downloading apps from the Play Store, the app instantly connected to my Google account and therefore my calendar.

If you don't have a Google calendar account you will have to add your events and tasks manually or import via CSV file which is the only file type you can import into the app. Also be aware that backup and export data to file are both only available in the paid version. Synchronization with Google tasks is also an upgrade feature as I don't use Google tasks just Google calendar this wasn't an issue for me but it may be for other users.

The calendar part of the app is nothing special. It functions very much the same as the stock calendar app (apart from being better looking). You can use it as isoTimer Calendar adding tasks or events to just its calendar or use the calendar of the Android system (stock calendar) as well as Google calendar.

If you use it with the Google calendar that’s when you can sync all your calendar data together so when you add an event to one calendar it goes on them all, which is much easier and saves you risk of missing to add an important appointment to one of your calendars.

There is also an option to link an appointment to a goal (more about goals and such later on in the review.) Like the tasks/To-do section of the app, the GUI is very attractive and easy to use. Adding events is a simple task just select the + button in the top right hand corner and choose to add either an appointment, notes or tasks and appointments/events can be linked to tasks (more on the tasks section of the app below). Reminders can be set for all parts of the app: calendar events, task, goals and notes. The reminders appear in the form of a pop-up or a status bar notification. Reminders can be set for any length of time before the event or task and you can set more than one reminder. Like many other calendars, there is a choice of ways to display your calendar, daily, weekly, monthly or as an agenda.

Although synchronization with Google tasks is not available, the app supports a great To-do/task manager which can be displayed as a split view alongside the calendar. The To-Do’s/tasks manager far exceeds Google’s task manager anyway as it has so many features and this is where for me the app shines. I found the GUI very attractive and easy to use. The task manager can be used to just set tasks or write notes but it also has a goal feature. The goal feature could be used for all manner of things like a school project or if you are trying to lose weight. The user can set out their goals in the 'my projects' section. There is also a 'big picture' tab within the tasks section where the user could list their long term goals for that month, for example if they were trying to save money towards a holiday.

The user can also use the ‘focus’ feature which is intended to help the user to fulfill the task or goal they have set themselves. I liked these features as they offer something a little different to the usual task managers around and I think they could be helpful if a person has a long term goal like saving money or losing weight. The task manager tab is a To-do/task list which allows for tasks to be sorted into lists depending on the task, for example work or personal and the tasks can be tied in with 'my goals'.

Notes can be added to the tasks as well as audio files, images and other files as well as contacts from your devices; locations can be also be attached to a tasks as well. I was actually really impressed by all the things that could be attached to the task. Also isoTimer can be connected to Google Drive so any images and files you attached to an event, appointment or task are also available and backed up to a isoTimer folder within your drive if you select that option.

Tasks can be set be as priority A, B, or C and task can be set to a date. Tasks can be attached to subtasks and set to repeat. Of course all of the tasks, goal etc can be set by date, or by date they need to be completed by and you will receive a little pop-up reminder if you have set your task or To-do to be completed by a certain date and time and you have yet to complete it. This is where the app can be used as a more basic reminder tool to just quite simply to remind you to do something at a given date and time.

The task manager in this app could have all sorts of uses; use it as a basic to-do / reminder or any of the uses I have thought of but I’m sure each user will have their own ‘couldn’t do without it’ use for this app.

Depending on your main use for the app, you can set the app to open on Tasks, Calendar or Focus. The app supports a number of useful widgets available for placement on the home screen. There is no way this app is going to let you forget anything. With all these great features and attractive GUI, I think I’ll be keeping this app on my tablet because it is so useful.

I installed it and really like the GUI interface and ease of use--EXCEPT...

I was very interested in what you said, "I really was impressed at ... how the app synchronized with Google calendar by itself without me having to anything." Except nothing I do will get mine to sync with my Google calendar. I checked to be sure both are associated with the same account, but I cannot find a 'sync now' command in it, and it sure isn't doing it on its own. wifi is connected, cell data is on, ????

ADDED further observations...while installing, everything refers to To-Do Calendar Planner, and that is what I commanded to install. It does not appear in installed items...what shows up is isoTimer, with a completely different icon. I also found a screen that shows calendars to display
-My Calendar [checked]
-one named with "my gmail address (Google)" [not checked and not checkable]
-one named with "my gmail address" (no parens) [checked]
-US Holidays [checked]

This is very confusing.
