What happened? Cannot open any longer. ### 1/5 — Crashes on iPad *2016-08-03, version 2.1* Fails to load correctly on iPad. ### 1/5 — Wasted my money! UGH! *2015-02-06* Wasted my time too, trying to figure out how it works! Plus it charged me for purchase twice! Beware!!! I saw some mixed reviews. Perhaps some people have emailed & received instructions from the developer, but if it's that difficult to figure out, it's really not useable. ### 2/5 — Useful but buggy *2015-01-11* This app solves the problem of how to copy and paste an event on the Calendar, which Apple's built-in app incredibly does not support. However, the app search function causes the app to crash. Sigh. ### 5/5 — It works *2014-07-29* Since the latest update, everything works perfectly except search. It crashes when you search for an event. I give it 5 stars, because I know they will fix this like all previous versions ### 1/5 — Worthless! *2013-08-30, version 1.7* A complete waste of money!! I want a refund!! Won't do anything it says its supposed to do! ### 1/5 — Very awkward *2013-02-23* Very awkward to use but most importantly some recurring events don't get copied between devices via the cloud. Don't waste your time or money. ### 1/5 — This app does not work at all *2013-02-17* From what I can tell, the app takes over the "repeat" function from iCal. If you attempt to set up a customized repeat in Calendar Tools, then the repeat function is no longer visible from i Cal. The home screen on Calendar Tools lists "events" by date that are taken from iCal. You can filter them according to date or event. You can see either see appointments according to days between two dates you specify, or you can see them according to the type ("x meeting"). From the home screen, you can click on an event ("x" meeting) and then add a "custom recurrence". You can specify 3rd Tuesday of the month; 2nd Friday of the month on a repeat daily/weekly/monthly basis. However, when you click "Done" nothing happens, so you cannot save the custom repeat. In effect, the very feature for which you buy this app does not function. Also, the app states in the FAQ that you can either add an event in iCal or in Calendar Tools with custom repeats. This is inaccurate on both accounts. If you open up iCal, you get the standard repeat options that comes with it (none, daily, weekly, 2 weeks, monthly, or yearly). If you open up Calendar Tools to add an event, you get the exact same options - no customizable repeats as advertised. In short, this app is a waste of money - it does not do what it is advertised to do. Don't buy it. I put in a request to Appiplayer to refund my money. If they are at all reputable and refund my money, or make the fixes to make this app functional the way it is advertised, I will add their response to my review and report the outcome. It's such a crazy thing that getting customized repeats is such an elusive function when it is available so readily on other platforms. Frustrated. ### 1/5 — Useless app *2013-01-23* When u install it- it announces it can't connect to inbuilt calendar; so all u get is useless app that creates double the work for you :(. The week view doesn't work, neither does the month view, all u get it this continuous long list that you cant separate :((( if u try to get help & u click on help button-- NOTHING happens...there is NO HELP; user guide is pathetic :((( don't waste your money! ### 2/5 — Does not make recurrance *2012-12-31* This program claimed to fix the bug of having an oddball recurrence (like wanting a task to happen every 3 weeks). Well the plan was easy enough to follow but the task would disappear on the calendar once it was edited. Very frustrating. If anyone can tell me what I'm doing wrong, please let me know. ## Frequently asked questions about Calendar Tools ### What does Calendar Tools do?
