CalenGoo gives you a fast and easy way to access and modify your Google Calendar with your iPhone, iPod Touch or iPad. It can also be used when you have no Internet connection, using the cached data. Changes are saved and uploaded the next time you are connected. The calendar view is similar to the web view of Google Calendar. Events are displayed using the same calendar colors that you use in your Google Calendar, even Google's event colors are supported (please see http://www.calengoo.com/cc ). It also recognizes which calendars are visible and which are hidden. So the view should match the view of your Google Calendar as much as possible. CalenGoo also has a month view similar to that of Google Calendar. It can be zoomed and panned to quickly get an overview over the events of a month. Zooming the month is done by using the two-finger-zoom gesture that you know from Safari and the photo application. A double tap opens the tapped day. It also supports the same kinds of recurrence rules as Google Calendar and displays recurring events correctly even when you are offline or scroll far into the future. You can also use Google Calendar's feature to invite people to events and see their status (accepted, declined, maybe, no answer). They will get an invitation email with links to e.g. accept or decline the invitation. Google Calendar has an integrated task list, called Google Tasks. Tasks with a due date are displayed on the corresponding days of the calendar. CalenGoo can do the same, it can sync this list, display your tasks in the calendar views and in a list view and it even makes your tasks available offline. You can edit and add tasks and the changes will be synced with Google Tasks. You either need a (free) Google Calendar account to use this app or you can use it with your iOS calendars. However using it with Google Calendar has a few advantages. To get more information, screenshots and a tutorial, please go to http://www.calengoo.com If you have any problems or suggestions, please send an email to calengoo@dgunia.de or take a look at CalenGoo's support website to get help. If you think the font is too small and hard to read, you can increase the font size of all calendar views in the settings under "Settings", "Display and Use". Features ( http://www.calengoo.com ): - Drag&drop to quickly copy and move events - Templates to quickly create similar events again. They can even be combined, e.g. one template for the location of an event and another for the attendees - Print/PDF function to print the day, week, month or agenda view via AirPrint or to email it as a PDF file - Supports the same recurrence rules as Google Calendar - Supports Google Calendar's event colors when syncing via OAuth2 - Icons can be assigned to Google Calendar events - Date/time can be entered using the iOS wheels or by using a keypad - Fast search function - Show/edit iOS calendars in addition to Google calendars (or instead of Google calendars) - Sync with Google Tasks and iOS Reminders - Reminders can be snoozed and they can be (optionally) repeated every minute - Birthdays and anniversaries of your contacts can be displayed - Zoomable month view, which can be configured to scroll horizontally (month by month) or vertically (week by week) - Events can be linked to contacts - Floating events and completable events - Photos and PDF files can be created and attached to events (via Google Drive) - Calendar selection bar to quickly show and hide single calendars - The location of an event can be opened with Apple Maps, Google Maps, Navigon, TomTom, Skobbler, Sygic, iGo or Waze - View/edit calendars that are shared with others via Google Calendar - Many configuration options to change the way the app looks and works

Time0 is zero-based time planning: every hour of your period gets a purpose before you live it. Just like zero-based budgeting gives every dollar a job, Time0 gives every hour a day. HOW IT WORKS Create a plan for a month or a project, add your work items with the hours they need, and spread those hours over the days. When every planned hour has a day, you have reached Time Zero. THE CLOCK The Clock shows your plan at a glance: the face is all your time, the indigo wedge is planned work, the emerald wedge is what already has a day. When both hands meet, the rim turns emerald: Time Zero. Plan more than the period holds, or put more hours on an item than it needs, and the rim warns you. ALLOCATE YOUR WAY • Table: work items against days, the whole month in one view • One item: one work item and its hours over the days • One day: a day's timeline with start times; Auto-arrange places the day's items one after another • Auto-schedule with one of four strategies you choose: Weekend Priority, Balanced Workload, Priority Focus or Front-Load Scheduling • Your own day limits for weekdays and weekends SEE WHERE YOUR TIME GOES Review shows your daily workload, estimates against allocated hours, and a calendar of full and open days. The work-life balance tells you how much of your time stays yours. PDF REPORTS Five report types for clients, billing and planning: Plan Overview, Detailed Schedule, Executive Summary, Task List and Time Sheet. On A4 or US Letter, shared from your device. WORK AND LIFE Plan life items next to work items, with priorities and your own hourly rates. Time0 shows what your allocated hours are worth. YOURS, ON YOUR DEVICE Everything stays on this device. No account, no sync, no tracking. Back up to your own iCloud and restore whenever you need to, or export and import your data as a file. MADE FOR Freelancers and consultants, project managers, accountants, creative and technical professionals — and anyone who wants to decide where their hours go before they are gone. • 14 languages • Seven themes, light and dark • A one-time purchase: no subscription, no ads From Time Zero to Time Smart.

Verdict
The clearest difference is update cadence: Time0 at every 5 days against CalenGoo Calendar's every 2 months. Time0 also leads on price ($1.99 vs $6.99). CalenGoo Calendar's advantage is chart position (#96 vs unranked) and device support (4 vs 2). On ads and in-app purchases there is nothing between them.
