Do you know what your app is actually valued at?
If anyone is interested in selling the ownership of any of the apps they are promoting here (or within their whole iOS portfolio), comment with a link to your app and I'll give a valuation based on today's app acquisition market.
Note: this is NOT an app review.
Also, happy to answer any questions on the market in general. Hopefully, this is an appropriate forum to offer this and that this is a value-add for you as a developer moving forward. If not, please let me know. I've taken a look at a handful of the apps here and some a really bread and butter for acquisitions.
