Good!

I’m just using this to support my Jewish friend as they convert; I can’t keep up with the holidays any other way. The UI is not very user friendly, and it’s just very confusing, but I finally have a place to keep track of the holidays! This is so much easier than anything else, I really appreciate the creator for putting this together.

Response from developer

Thank you so much. I wish I was more talented for nice UI... I haven't given up though! At some point I will address this issue, with G.od's help!

Added ads

App is now cluttered with ads and they have the audacity to try and charge 1.79 subscription to remove them, at least make it a one time payment. Greedy

Ad getting in the way of a great app

UPDATE: I do now see an ‘X’ that lets me close the ad. But still, I’m not going to rent a car after checking the zemanim. This is annoying addition to an otherwise fantastic app.

What has happened? This morning I was up extra early and needed to check the time for tefillin and Shema. I open the app and up pops an ad for car rental. I see no way to dismiss this abomination. Not even after several times force quitting and trying toreopen.

Response from developer

Dear user, I am sorry about your bad experience. You probably ran into a bug just that very minute when you couldn't close the ad. It is of course fixed long ago by now. An ad is just an ad -- no abomination here. You don't HAVE to rent a car, you can just skip the ad and enjoy your free app for free, as you've ever enjoyed it for free. Just skip the ads. Also, I limit to a maximum of one ad per day. Nothing very much harmful. Thank you EDIT: Thank you for your update, I appreciate it. Nobody is going to rent a car when checking zmanim or saying Asher Yatzar. An ad is an ad is an ad. When you watch a free TV program, and there is an ad for a car, you don't have to buy a car The TV channel gets paid for you to have a free program. That's how advertisement work. And unlike TV and unlike EVERY other app, you don't even have to wait through the ad. You can just skip it.

Great app

Very useful app to help keep track of zmanim it really is my everyday companion and I love the yorsite/biography about th rabbis as well as all the tefilot your doing great keep it up!!
