AppShopper

After AppZapp discontinued, I found AppShopper and started using this.
There’re bugs like we can’t see some apps although having typed correctly and searched it, and you see wrong/ previous prices in some apps. In this case, I search for it and set an alert on other alternative services like AppAgg.
Also, you can’t set an alert at a specific price or becoming free: the only option is that you get all alerts to notify every price drop. In this case, I searched it and set an alert on other alternative services like AppAgg.
Moreover, the most frustrating thing is you correctly perfectly type a specific app name, and frequently many other apps appear, and you find it difficult to find a particular app. You have to scroll and tap next again and again. Terrible algorithm. In this case, I searched it and set an alert on other alternative services like AppAgg.
You can’t search for a developer’s name. You have to search and find an app first and then tap dev’s name.

I noticed I had been wasting time and energy with this app and I can switch to another alternative like AppAgg and there’s no point I keep using and been frustrated with this app.
I’m not related to AppAgg. You can find these common problems using this. I used another alternative like AppSliced and NEVER experienced those terrible problems above.
I recently found AppAgg on this site and its design and switch from Appsliced. However, AppSliced is also good, and Appsliced recommends you to buy an app at a specific price calculated on the price history.
However, on AppSliced, you can’t have a list and check apps you own: only you can set an alert.
AppAgg allows you can have multiple lists.

So I extremely recommend you to avoid to sign up for AppShopper and simply choose other alternative listed below here. If you’re already Ian user and created lists and registered apps like me, you had better considering switching to AppAgg or another alternative.
