I wish I could share my calendar with people so they can see my schedule. I also wish it could be a widget on iPhone. Maybe an updated look as well ### 4/5 — It’s functional *2025-12-30, version 5.1.2* The app is functional enough. It cross loads everything from your calendar app which is nice. I wish it worked on Apple Watch though ### 2/5 — Great. But one bug kills it. *2024-12-08, version 5.1.2* It was a pain to set up my shift schedule, but once I got it running, I liked it. But twice now, it has randomly deleted all of my events. Really has put me in a pickle a couple times. Sadly, making me look for an alternative app. Can’t risk that. ### 2/5 — It’s good but wish was better *2024-06-02* I like the app and use it a bunch. I wish that it had a lot more customizing options. I wish that the shift was designated by the number instead of utilizing a line below. This way we can have more of a instant view of your to do list. Some pay days include our FLSA hours and I wish I can mark them somehow to be able to identify them at a glance. Also, I wish I could customize when I work a holiday or vacation day. I can work them and get pay for them, if I try to put one in, it automatically puts me off which is not accurate sometimes but I can modify that ### 4/5 — Print *2024-05-09, version 5.1.1* Would like to know what are the plans to make it where a can print it off … ### 4/5 — User friendly and simple *2024-03-04* I was bummed when my old calendar app was no longer available for download (new phone). So a quick search of the App Store & I found this. I hesitant since I’m an EMS provider. But this was very user friendly and easy to build my schedule!! I love it ### 3/5 — Holiday icon disappeared *2023-12-09, version 5.0.2* Happy for new updates, but holiday icon no longer show in calendar. ### 4/5 — Changing shifts. *2023-07-11, version 4.0.3* I enjoy this site but I have been moved shifts this year and it seems very difficult to change the calendar. If you could please look into this. ### 4/5 — Love the app *2023-03-21, version 4.0.3* I love using the app for myself. If it was just easier to figure how to sync your app with your significant other that would make it easier. ### 4/5 — Dark mode *2023-01-30, version 4.0.3* Great app! Although I wish it included a dark mode. If it does I can’t figure it out. ### 2/5 — It’s good but wish was better *2023-01-24, version 4.0.3* I like the app and use it a bunch. I wish that it had a lot more customizing options. I wish that the shift was designated by the number instead of utilizing a line below. This way we can have more of a instant view of your to do list. Also I wish I could customize my FLSA start and end date by somehow being able to add a marker on any given date without just adding to the do to list and being hidden on the bottom of the list. Easy things that they can do to make it much better. I also wish I can customize my paydays. Some pay days include our FLSA hours. I wish I could mark them so I know chica are which. Doesn’t matter cause no one listens. I have been saying this for years ### 4/5 — Color code *2022-11-18, version 4.0.3* Wish I could color code a day to make the visual easier. Nice seeing colors of my shifts but wish I could change colors of days to know what days I am busy or not ### 5/5 — Great app *2021-12-31, version 4.0.3* Highly recommend this app! Everything you need. ### 5/5 — Perfect App for Firefighters *2021-12-21, version 4.0.3* Really enjoy using this app to keep up with my crazy Schedule so does my wife with keeping up with it. ## Most critical reviews (10 lowest-rated) ### 1/5 — Calendar Access Changed *2024-02-26* Our family uses one iCal account for shift and OT days on our phones and using the Fire Sync app USED TO allow me to view a whole month of just my spouse’s shift and OT days because of the app option to give access to sync “select” calendars. Now with having to sync “full calendar access” only this app is completely useless in keeping track of my spouses shift and OT days!! Uninstall. ### 1/5 — Trouble app *2023-11-28, version 4.04* Erased all my info for work second time it has done that ### 1/5 — Completely useless *2022-03-10, version 4.0.3* When I try to verify my department or even a personal email and hit “send verification” absolutely nothing happens. The app is useless without being able to use all of the features. Support has been no help. ### 1/5 — No longer Syncs *2022-03-09, version 4.0.3* This app used to be great because my husband and I could view each other’s calendars. Apparently this feature no longer works. I have reached out to customer support to fix this and no one has responded. ### 1/5 — Schedule won’t publish *2021-12-29, version 4.0.3* I can’t get my schedule to publish for my coworkers to see. Can’t figure out how to find a customer support number or email. Very upset ### 1/5 — Bug possibly *2020-01-31, version 3.9.3* I keep getting an oops message and when I go to search my department the app crashes ### 1/5 — Colors *2020-01-27, version 3.9.3* For someone who is green red colorblind the green, red, and orange are impossible to see the difference. Definitely needs a colorblind mode. ### 1/5 — Major bug *2020-01-17, version 3.9.3* When entering info into the ordinary category and location no problem. But when you edit the date/time or notifications fields, the category and locations fields delete. ### 1/5 — Crashes on all my devices since iOS 13.2 update *2019-11-05, version 3.9.3* I love this app. Then the iOS update came along and “poof” I can’t do anything on it except open it. I can’t put an event in, update a benefit or trade......as soon as I tap the “add” button the app crashes. It doesn’t matter. I also can’t scroll past November without crashing. Fix these bugs please. ### 1/5 — Bad Cus. Svc. No Kelly Days *2019-01-10* I requested feedback as it pertained to font size within the app. I received a swift reply as to how to remedy the issue. I subsequently have sent multiple inquiries to see if there was a way, or if they were planning on adding Kelly Days under the “Benefit” type of time off. It has been weeks, and still no reply, I was hoping to set my 2019 calendar which includes Kelly Days. I have no choice but to shop for another fire calendar app, and cannot in good faith recommend this app to other firefighters and their families, especially those that have Kelly Days. ## Most praised reviews (10 highest-rated) ### 5/5 — Great App! One suggestion *2026-06-02* Appreciate no ads for this app! Works and runs great. Highly recommend and props to the owners for not putting ads! Only calendar app I use. A suggestion I’d add is having the ability to choose between reflecting trades immediately after they’re inputted on the calendar vs after the date worked. Having the ability to choose between those 2 would be great. Thank you! ### 5/5 — PTJ *2026-01-20, version 5.1.2* Seamless and efficient ### 5/5 — Calendar review *2025-09-03* I like the app but I don’t like that some events that are on the calendar I can’t delete future events. I have to delete every year. I don’t care about a lot of those. I think the creators must be Muslim. ### 5/5 — Share capable *2025-01-24* Being able to find others who already made a schedule makes it super easy to load a schedule. One improvement I suggest is being able to change the color of the days for the days that you took leave personally. ### 5/5 — Perfect setup for me! *2024-10-23* I really like this app. It’s easy to set up and keeps track of Kelly days, trades, and overtime. Plus a whole lot more. I also have my family using it as well. The notes portion is fantastic for keeping track of issues on the truck. ### 5/5 — Great app!! *2023-07-22, version 4.04* By far the best calendar on iPhone. It’s an added bonus that it’s a Fire shift calendar. ### 5/5 — Great app *2023-05-17, version 4.0.3* Been on the St Louis fire dept for close to 20 years. This app has kept all my Kelly days straight, and adding V days and H&O days is easy as it gets. Highly recommend this to any firefighter on the Kelly schedule ### 5/5 — Great app *2022-10-12, version 4.0.3* Easy to use and convenient shift calendar. ### 5/5 — Fire calendar *2022-08-20, version 4.0.3* Convenient and easy to use!👍 ### 5/5 — Review *2022-04-19, version 4.0.3* This is a great App it’s very helpful I love it --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
