One Calendar

It actually syncs with ics web calendar!!! I own a business which accepts on line bookings. I need to know when new bookings are made so I don't miss appointments. I tried dozens, and as with Google, they didn't update on demand. This one does it!!! Easy set up, works/syncs perfectly. Linking 4 cals total. The only neg I'm having is when i open an item imported from my booking software, it reads in UTC time. but that's only when i open to read, it displays correctly on the ap.

Sync works in save power mode!! My calendar app that came w/my phone doesn't sync w/my other devices while on power mode. After downloading a couple of other apps this ONE syncs just fine. I like the widget option of making it transparent. Wish it had more theme options. Also can't add my Samsung account so reminders don't show up on the calendar. Otherwise great working app!

I've been using this app for a few years. Always loving it. Recently I just got a new phone, so I migrated all the data to this new phone. And all of a sudden I noticed the "Premium" feature... I was quite confused because I was sure OneCalendar was 100% free on my old phone. I double-checked and found out I was right ---- all the premium features on the new phone can be accessed on the old phone FOR FREE! Pretty upsetting especially when I once could use those features for free...

I selected 4 stars, although it's more like a 4.5. I actually really like this calendar app, the only thing I wish was different would be to allow people to choose the color of the event or at least have 3 options of colors without having to pay for the subscription. It's a little bit silly that they only let you use the one yellow color if you are using the free version. At least have yellow, red, and blue on the free version, and all other colors + custom colors on the paid subscription.

It does everything that I wanted to do and is connected to all of my other calendars. The sync is much faster than other apps that I have used. Edit 3/10/24: Yup still use it. I am not as business savvy as a lot of other people but it does everything I needed to including tracking appointments and making my own stuff on a daily or weekly basis repeating items daily weekly and whatnot. Still like it, will keep using it.

The only calendar that allows everything we need in scheduling appointments for our salesmen. Has GPS, easy movement of appointments for cancelations or last minute add- ins, and allows notes on client request . Everything is on one page, so there is no going back and forth to view time, date, address, or notes. The reminder alarms are an added bonus for us. There is no need to train on this calendar because it is pure simplicity at it's best.

I previously gave this app 5 stars. I recently lost ALL my entries. They simply disappeared and when I tried to reload what few I could remember, it gave me a message that I needed an editable account. An uninstall and reload didn't help so I sent in a request for help. Totally ignoring me. When it worked, fantastic app in my opinion but losing all my data and being ignored doesn't work for me. Update, somehow, someway I was able to get my data restored so moved my rating to the middle.

What I have been looking for. Clear and useful UI. I wanted an app where I could see and edit several calendars so I could see my full schedule in one place. I also have a work calendar that, due to work account policies I can't edit from external app but this works fine for me and isn't a limitation from the app. Works better than native android Google calendar. Happy to pay once and not have to create another account for a subscription based monthly service I don't want or need.

It's the best, most organized calendar in ALL the appstores, first it has you choose from a fair pick of backgrounds. Then as SOON as you input an active account (or sync one from another device(s) every event you could ever have to attend is laid out for you as soon as you sign-in and choose a format. (I choose google, most efficient option). If you want everything laid out at the click of a few buttons and to only have to add recreational events, DOWNLOAD. THIS. APP.

There is a lot to like about this app. It's easy to use, intuitive, customizable, and pretty to look at. But as others have pointed out it's missing the ability to set more than one reminder for the same event. Also invitations to events are not showing up here as they did with Google calendar, even though this calendar is linked to my Gmail account in the same way that my Google calendar was. Developer, please let me know what I can so I can do to reliably see my event invitations.

I like some of the app and not other parts of it. The feature to put the current date in another color does not work. I like the dates and events listed below the calendar. However, I do not like the lines thru the dates. It makes it hard to tell the dates. I do not like the colors for the events. They are too bright or too dark which makes them hard to read. I would prefer soft pastel colors or even better, no colors.

I have used this for over 5 years. I evaluated 5-8 other calendars by downloading them. This app offered most of the features I found are most often needed. Repeat function doesn't always get the right day of the week. Love the color coding!! 😍 11/23 update: after I changed to a new phone this summer the color coding no longer works without paying, hate that! Want to decrease to 4 stars, but can't!!; 2/24 just discovered i can use color coding again, LOVE IT!! 🥰

I've been looking for a calendar app that works with my self hosted Nextcloud server (version 29). The app is incredibly easy to use and setup. Very simple GUI which is exactly what I want. I haven't had it long enough to see if the notifications work or not but it does sync without issues to and from my Nextcloud server. Very impressed so far. Also, I looked around the app to see if there is a donate or send me a beer/coffee but didn't see one as I want to send them few bucks.

Works well to sync Google calendar, Outlook and Windows 10 calendar apps. I haven't tried it with others. Syncs best if you enter the appointment in One calendar first. It doesn't always pick up entries that you put into other calendars. If you have multiple calendar apps on your phone, tablet or computer, it will result in multiple reminders. I don't know how to get around that. For reminders from OneCalendar you have to go into the calendar entry to change the reminder time. I have not found a simple way to delay the reminder when it appears. If you are out of cell coverage, calendar is slow to load because it cannot sync.

I think the app could be good, if it had an option for local only. I don't want to have to sign into and connect to another calendar service just to use a calendar. Make an option to be able to set a appointments without forcing you to connect to a separate internet calendar (that I could just download instead because all of them have their own apps) and this would be a great app.

Love this app. It is very easy to use and has lots of options to customize. It is making my appointments very easy to see and manage in one place. Thanks for this. Update: I am having trouble with getting my events (reservations and flights) that were synced from Gmail. These events appear in every other calendar app that I have, but not this one. This is frustrating. I reached out to customer support twice, but there was no response. I'm considering switching to another app.

Brings all my calendars together. you can't invite people from the app but you can share appointments and add people to events. for no apparent reason, it's not possible to edit an event and make it recurring, which is annoying if you add an event and then later want to make it a recurring event. but overall the app is intuitive and the widget works well for me.
