Looking for a calendar app for both iPhone and laptop, besides standard iCal app?

IIm trying to find a nice calendar app that can be used between both my laptop (Mac) and iPhone. I need it to be able to be color-coordinated and also to have daily, weekly, and monthly views. Preferably free, but willing to pay a little bit for it. Found one I really enjoy, but between the desktop version and the phone version, it's more than $30 and IIm not sure I want to pay that much.

Google calendar will work on a browser on your laptop and works on the iPhone calendar app.
You need to set up a gmail account to start the process

  • Water damage and opening iPhone 5c both puts it out of warranty, so do both? If having water damage in your iPhone 5c means you aren't covered by warranty, is it acceptable to open it and try to fix it as opening it also means it isn't covered by warranty. Therefore if you can't fix it yourself, apple can still take it out of warranty?
  • Update required to sync ical to iphone? I have not updated my MacBook to iOS x.iTunes used to be able to sync my iCal calendars to my iPhone. With the latest version of iTunes, it seems as though the sync happens between calendars on my phone and iCloud -- not iCal. Is it necessary to upgrade now to allow the sync?
  • There's a problem with my iCloud and iCal? I have a Macbook Pro and a Iphone 4s that is not updated to ios 7. I have changed nothing recently. On my computer my ical icon jumps and says there's a problem and to check settings (which I did). I even changed my password. And on my phone it keeps on prompting me to enter my apple id password even if I enter the updated one. What's going on and how do I fix it?
  • Is there an iPhone calendar or planner app that I can sync to my laptop (PC)? I'm a busy grad student and need a way to keep my calendar with me at all times and I hate using just the iPhone to do so! I like to be able to type on the computer when possible, the touch screen on the iPhone is just so tedious! I'm looking for something that I can pull up on my computer, edit information, then have it also sync back to the iPhone app or something of the sort and vice-verse. I have no idea if this even exists but would be grateful to any help offered!
