openinwa VS matrix-puppet-signal

I use an app called "Open In WhatsApp" which lets you paste / write a phone number and it will open a conversation with that number (by using android intents). You can also share contacts from the Phone app to this App.

FWIW: I've been using whatsapp without access to my contacts with the help of this little app: "Open in Whatsapp"

You can enter a number in that app and it will launch a conversation with them in whatsapp. I think it makes use of the API mentioned in sibling comments.

- Client with simple UI, polished UX, and not just a smoking pot of features: FluffyChat[3] is mostly there.

- Server of which I can guarantee the uptime. Dendrite should lower the resource usage for a ~5-100 accounts server, and decentralised identities[4] would allow falling back to another server (such as a friend's).
