Recommendation *****

I have been using this app for sometime and enjoy having it. I started with it back when it was known as Leaky Nozzle and as mentioned in a previous review when it changed over to spark there was an uneasy time till I called and the problems were quickly resolved and have not had any problems since. I am a very happy user of this app and recommend it to others and friends all the time

Doesn’t want to update


This developer, after charging all of us long time users again and again, now yearly, says he’s not sure if an iPhone X update will be coming to the app because “it’s costly.” REALLY??? If you’re going to charge us yearly, this app should be PROMPTLY UPDATED! The iPhone X update should have been done before the iPhone X launched, like most other developers have. This guy is very greedy! To top it off, I keep getting prompted to review his app even though I have option turned off in settings. This guy wants to make recurring money with yearly subscriptions without having to pay for the work to keep app updated.

Developer Response

The update for iPhone X is coming out this is false information. It is currently being looked into and worked on just no ETA on release yet. The app functions without a problem on the iPhone X and with any new device it can take some time before all apps are up to date. If you have been a long time user of this app you should then know that it is consistently updated and all issues are resolved that are reported. Maybe not in the time frame you need but they are taken care of. I am a one man show not a huge corporation but things are taken care of and all emails are replied to.. That should say something right there. This app is a yearly subscription of .99 cents a year I am sorry you feel this is to much. Please be patient as we work on updates

This App is fantastic


I first started using this app when it first came out as Firehouse scheduler. I have liked it from the start. It even handles our odd schedule rotation. Being able to share it works well, as my family has the app and I just send them my new schedule, so they know when I’m working and when they can get a hold of me.
