Mobile app builder as a bot for Telegram?

Question

Android

Salute, colleagues! A question for Saturday evening, maybe even a theoretical one.
Sawing a bot for Telegram is a pleasure! The client added the bot to contacts, logged in and clicked the buttons. All the functionality of the bot lies entirely on the server (webhook + api), and any change in logic or bugs does not affect the client in any way - he does not need to click "Update application" and listen to any warnings from the Market. He just continues to use, and the developers debug online and fix the bot. 21 century.
Not so with mobile apps. You need to release the build until it spreads to customers, more bugs are found and the process is repeated. Many clients turn off auto-update and it is almost impossible to reach them - the old version is no longer supported by the server and the client complains about a broken application in reviews and support. Well, a bunch of versions of Android add entertainment. Sadness.
Are there app builders that have their logic and elements hosted on the server? Yeah, like HTML5 + WebView, but not so slow :) For example, an application checks a new version of logic and elements at startup, and works further if everything is fresh. If not, it downloads and updates the interface in the background.
For 99% of applications, it is enough: signs, forms, buttons, lists, a map, etc. Maybe some React Mobile in conjunction with something? Following the example of Telegram, the server is responsible for everything in real time, since the Internet is now cheap.

Ionic deploy: https://docs.ionic.io/services/deploy/
I'm just porting my debt accounting telegram bot https://t.me/DebtsTrackerRuBot to Ionic and doing updates through this service.
On the iPhone 6s, the new version is loaded and unpacked in 3-4 seconds.
Microsoft also seems to have something similar for Cordova apps.
