Then gave up and uninstalled it. Waste of $2. ### 1/5 — Calendar days are purple *2018-09-03* All calendar days are purple and days won’t change color on setup ### 1/5 — Swindled *2018-08-28* I’m a fire fighter not a computer programmer! I even resorted to watching the dry burnt toast video on you tube on how to use this abortion of a shift app! I want to put in my shift and see the results a year in advance, not waist the pre cancerous life I have left trying to salvage the 3 dollars I’ll never see again trying to figure out this app! ### 1/5 — Disappointed *2018-01-31* I couldn’t get this app to work for 24/48 shifts. Therefore it didn’t meet my needs and I deleted it. Money lost. I wish there was a way to get my money back. ### 2/5 — Not very good *2017-12-06* Only shows one month at a time. Complicated compared to other free apps. ### 3/5 — Update please *2017-10-31, version 8.1* Just purchased in hope it will Ron with iOS 11 as my older version won’t Now found out this won’t either very frustrating as it cost me $3.00 These apps are best so far so please update ### 1/5 — AWFUL!!!! *2017-02-10, version 8.0* Do not waste your money.

You could scroll through and choose just about any shift rotation. My phone recently took a dump. When I put it on my new phone it’s completely different. It’s terrible now. Really disappointed, cause this was at one time the best free shift calendar. ## Most praised reviews (10 highest-rated) ### 5/5 — So simple *2020-12-11* I don’t know why the reviews are so low. I’ve used this app since 2010 and it’s so simple ### 5/5 — The app won’t open on my iPhone anymore *2020-11-25* I can’t get the app to open then I tried deleting and reloading now it won’t allow me to opt ten or download? ### 5/5 — Thanks *2017-05-19* Thank you for a great app!! Does everything I need. ### 5/5 — Great app *2017-02-11, version 8.0* Works great ### 5/5 — Awesome *2016-12-17, version 8.0* Way better than leaky nozzle! ### 5/5 — Great simple schedule *2016-05-08, version 7.7* A great schedule app for any shift you may work. As for the fellow who claims Easter and Christmas aren't on as holidays, he's special, you just have to add Christian holidays as a choice along with US holidays! Overall good app! ### 5/5 — Excellent App and even better support. *2016-01-28* My whole family depends on this app and I had one suggestion that I made and within days it was completed making it more user friendly for all of us. Thanks guys. Keep up the great work and pushing the envelope. ### 5/5 — Great Shift Calendar *2014-11-09* I have waited a long time for an easy to use and easy to modify firefighters shift calendar. I am on a 48-96 hour rotation and this app worked perfect. Modify the colors and rotation schedule with ease. It places holidays into it and items like vacation and Kelly days. You can add notes to any day or event you want. Was well worth the .99 cents. I would highly recommend it to any shift personnel. ### 5/5 — Great app *2014-10-10, version 7.2* This app works great and the updates are very stable! ### 5/5 — Won't work *2014-04-02* I have had the app for a couple years now and am very happy with it. For some reason it now keeps kicking me out...I NEED this app, can someone help me as I don't want to re-pay again?!?!?!?! --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
