LessChurn vs Mobirise Website Builder

LessChurn provides a fully customizable iFrame, which you can embed in your app wherever your account deletion happens.

LessChurn is a service designed to reduce churn by helping your users right before they delete their account.
Replace your typical Delete my Account button by giving your users helpful options (such as “request a product demo”, “contact support with a question”, “get a discount for X months”, “extend trial for Y days” etc.).

Create awesome mobile-friendly websites. No coding and free.

Mobirise is an offline app for Window, Mac, and Android (iOs version will
be available in November) to easily create mobile-friendly websites. Mobirise
is perfect for non-techies who are not familiar with the intricacies of web
development and for designers who prefer to work as visually as possible, without
fighting with code. Also great for pro-coders for fast prototyping and small
customers' projects.
Key differences from traditional builders:
* Minimalistic, extremely easy-to-use interface
* Mobile-friendliness, latest website blocks and techniques out-the-box
* Totally free for commercial and non-profit use
