I'm fully on the Apple ecosystem nowadays so don't feel this pain anymore, but I would have used this before. Not sure if I would have paid for it though
It doesn't matter which ecosystem, just try to send a list of tasks \ shopping list from Apple to Android without registration. This app solves the 1-2-3 problem easily.
How did you get 100k+ downloads on Google Play?
The application is very popular with Android users because it is really cool and simple. Many people write letters of praise and reviews - read them. And by the way, not 100K+ but a lot more)
It is very strange that Apple users are always skeptical about the application and write about notes and a notebook embedded in the iPhone and the ecosystem ) The gap in the number of downloads is enormous.
Web app?
Written on the flutter (ios\macos m1\m2\android). You can perform tasks by simply clicking on a link on the internet without installing the app.
