    Did you monetize this app and if not did you encur charges for your infrastructure? If you did monetize it, how did you do it and how did you decide about margins?

      I guess it is a Donationware – done via Patreon

    • http://mattkremer.com Matt Kremer

      Great question! Right now it’s fueled by Patreon donations 🙂 I’ve got over 40 donators at this point, and it’s growing everyday. I am definitely going to be adding a subscription to the app for several features though (like cloud backup of your checklists) that will most likely be a few dollars per month. As for charges, I thought it was going to be worse than it actually was, I wound up spending about $7 on Firebase Hosting so far.

    Very interesting article and expanding on the question @mike_lallemont posted; what costs were incurred getting from “Day 1: I was live on Firebase Hosting…” to “Day 17: The app started trending at…”? Working on the assumption that after being downloaded 40,000 times you will have graduated from Firebases free tier and also assuming that you are using their Realtime Database or Cloud Firestore solution as well as Hosting, what sort of cost have you incurred in that first month including the App Store & Play Store fees? Would be really useful information for others wanting to bootstrap their own app.

      Hey there! Right now I’m just on Firebase Hosting, and don’t use their storage solution quite yet. Total charges have been around $7 since launch. $5 of that was the first day when I was serving all of the images off of Firebase even if you downloaded the app. Bad idea! Once I figured that out it’s only been about $1-2/week.

    Great article! Your app is phenomenal! And Ionic is amazing too, of course. 😁 Thanks for posting this, Matt!

  • Chuck Knowles

    JUST ionic? what other features did you add in? any stencil or capacitor?

  • Joe Ruder

    Looking at the app now in the android store and the last 35 reviews have 28 of them complaining that the app will not open / crashes. Have you found what is causing that? The reason I am asking is we are looking to develop a LOB app that simply cannot crash (well…you know…not all the time at least). Looking at Ionic and found your Blog. Thanks for a really interesting article!

      Hey there Joe! I’m on a super early employee-only version of Ionic Deploy so we can iron out the kinks before public releases. We’ve fixed about 80% of the crashes already and are very close to fixes on the final 20%! I’m taking one for the team so we can make sure Deploy works great for you 🚀

        That sounds great. I just purchased the team subscription of Ionic Pro yesterday for a small internal team to start learning with. Looking forward to it!

  • Timon

    Why is the app on so many Android devices not properly working? Could you give a statment about that? Thanks

    the App is removed from Play store

      Hey there! Going through some issues right now having to do with iFrame embedding YouTube videos, which can play in the background by accident unless you program them to stop (against YouTube TOS). Highly recommend if you’re planning on putting YouTube videos in your app to use the native plugin instead 😅 I fully expect to be back up and running in the next day or two after I hear back from Google!

        I had the same problem with one of my ionic app, google rejected when I submit toplay store due to policy violation with youtube playing in background , later I fixed https://play.google.com/store/apps/details?id=nk.rash.newvartha, now its there

        • william rotich

          Had the same same problem..Thought i had fixed it and was rejected again…How did you do it kindly..

          • Abu Nj

            its not allowed to play youtube videos i background, so I just used ngif to check whether the page is active to play video

            ionViewDidLoad() {
            this.play = true;
            }

            ionViewWillLeave() {
            this.play = false;
            }

            <iframe allowfullscreen *ngIf="play" [src]="youtubeUrl"

        Had the same same problem..Thought i had fixed it and was rejected again…How did you do it kindly… Will be regretful if you do a small article on YouTube.

  • Alex

    Hey, nice work. Which version of ionic are you using in this project?

  • Omurbek Kadyrbekov

    Can you make it open-source? It will be good to learn from production ready app

  • Parshav Shah

    Great Inspiration for me !
