iRT Calendar

I've been using this app since early beta for its ability to do custom alarms and icons.

Have used this app for years with every device. Any problems I ever had the developers fixed within 36 hours. This calendar is the best.

I have tried most others and I always fall back on iRT.

Thead and shoulders above the others

The best

This app makes useless stock calendars ad awesome as Blackberry's! I only wish the search wasn't limited to 5yrs...

Best calendar I have used, but need more icons!

Love how every detail is customizable!!! Nothing was left out!!! I manage a medical practice keeps track of everyone apps! PURE PERFECTION!!!!

Duplicates events and continues to show events that have been deleted.

I wish there were more icons and that the ones available were more defined!

Love it. Best calendar ever

Needs its own add/edit screen. Also "add last number" from call log in the add/edit screen. Using other calendars to add events places the user in that calendar app even after saving event! Doesn't make sense.

Having problems with sync all of the sudden. Some things sync fine. Others not at all. 5 stars if fixed.

works great on my Droid...needs a few more event icons

Great app, but would love more icons.

I used to love this calendar but now it does not sync properly with my google calendar. No resolution from developer. Don't buy this app. No stars.

When irt adds widgets like Jorte and Business Calendar, I will return. I like having a calendar on my desktop.

This is a very solid good working application with no errors and obvious continual effort for improvement. BUY!

Simply the best.

Best calendar app by far! Love all views, especially agenda. Fantastic tech support, gave me the update needed to be compatible with my phone asap.

IDEA of this calendar is good, but REALITY is its 'buggy'. Dev is good about helping, but had to contact 2x in 1 wk for2 different issues?Frustrating!

Wow. Much better than Droid X calander app. Very nice.

This is the best calendar I have found! Thank you!

Excellent calendar. Well worth the money spent.

Best of the calendars

Latest update fixed the weird issues caused by the Jellybean update. Works great for me again.

Not working after S3 update to Jelly Bean. Period. Update: New iRT update makes it again my fav calendar app!

I love almost everything about this calendar. But I'm going to have to put it down. Two broken hearts, this app has caused me. I had (didnt want to just because of this calendar) to do a hard restart because my phone was acting up. Both times I had stored my life in this calendar and my stuff didn't return. My heart is torn to pieces. I'm going to have to find a diff one now. Sad face!

I switched from a Palm Pilot to the HTC Evo when it came out almost 2 years ago. I hated the calendar. I downloaded the iRT calendar and never looked back. It's easy to use, love the icons, and if I emailed the developers they responded within a day. Very impressive.

I have an problem deleting repeating events without the app simply stopping, but otherwise this app is great for me.

This worked for me - "Download from Google Play the free "Set Calendar Colors" app. Use it to change the color of your calendars. iRT Calendar will then use that color. Note that if you go to iRT Calendar -> Menu -> More -> Preferences -> Calendars to Use, it will delete the colors again and you need to set the colors again. Just avoid going to "Calendars to use". We also noticed that the auto sync of the Android calendar resets it back to the invisible color. For now just use the workaround."

This rating was 5 stars until my phone updated to Jelly Bean and this app stopped working properly. I emailed the developer and never got a reply. Update please. - Original review - I've been waiting for a calendar app with the agenda day view similar to Windows Mobile. This app is perfect for that!

Crappy service. Program won't validate even though I purchased it. Their response "try validating it again". I havetried dozens of times. I have contacted them at least 4 times. No further response. Don't buy this program!!!

In ICS on my RAZR MAXX, after using extra edits the item disappears! Please fix.

Great app. Meets my needs and syncs well with my home and work calendars. Need more icons!

Absolutely fantastic displays on a phone, especially with being able to increase font sizes to make everything perfectly legible. I wish there was a way to make the item titles all in black. Hopefully this will be updated soon making it the best tablet calendar program ever.

Used to be great on my old phone, but an upgrade to a galaxy note 2 has rendered it useless as it no longer displays my appointments, just blank spaces. No response after 3 days from support.

Use it constantly

Still waiting for an update to work on the Galaxy Nexus. It doesn't work.

WAS 5*. MISERABLE support! Now that Business Calendar has irregular repeat scheduling, GET BUSINESS CALENDAR INSTEAD. Samsung Galaxy Note GT-N7000 GB 2.3.6
