I check their support all is showing as not available and then I send an email for support the reply was we stop the service and delete the app. I asked for can I get back my data not sure is it possible or not. They anyhow closed the service. I've checked the whole email I never received any announcement from this company/app. And I lost all my data of who wants which item. Hope at least I can get back my data of who applied for which item. Already some customers are asking for the restock, I am not able to check who applied for what. I've totally lost trust of this company which they take all my customers' data of what interest who bought what but I wasn't even able to get back my data of the whole purpose of why I used this service for. Anyone using this company software please consider well. They can be anytime close the service without notifying you, and most probably won't get back your data. Now I have to ask my whole customers want which item to restock. This is worse than never used. If at least notify me about this before they close the service, I could go and prepare for that. But they did non of that.

Hi there,

James here from Booster Apps! Thank you for your feedback and I'm so sorry for the trouble loading our app.

It looks like our server provider has resolved the issue that was causing our app to not load for a small percentage of users. The app is back up and running as expected. I've also reached out to you over email with how to gain access to your data. Thanks for your patience and I'm so sorry for the inconvenience here.

Booster provides unmatched customer service - for a free app even! The Back in Stock app was not meshing properly with our theme and Booster was able to customize the app to our theme within just a few hours. Thanks guys!

Me gusta bastante. Es práctica y customizable. Llevo poco usándola pero hasta ahora genial. Pienso que necesito más tiempo para conocerla mejor. Uso el plan gratis y correo excelente

On the positive side, it's free and works exactly as described. Customer Service is excellent. I didn't give five stars because there's room for improvement. I would love the notification button to appear near to the cart rather than at the top/bottom/left/right of the screen. And not a fault with the app, but it doesn't work with Apple platforms.

First off, this app is FREE, so that's a huge plus. They finally implemented email notifications, so that's a huge relief. Back-in-stock alerts still don't work on iphone, but they do on android, which is the only reason it's not getting 5 stars.

Love love love this app! While all the other apps I looked at were quite expensive for a start-up website, this one offers exactly what I was looking for and for free! I also received an email the day after the feature was set up on our website to confirm everything was working well and to see if I had any more questions and when I did, I received a very quick response. I have installed a few of the Booster Apps on my website and they're all great. Thanks!

Great app, even better customer service. Level of support for a free app is out of this world. We have used other apps by Booster as well and would definitely recommend.

I wanted an app to allow customers who wanted to be notified when a product was back in stock. It works.
