i would go old WhatsApp way, let people use it first year for free which it's plenty of time for social networking effect to work and decide if it's worth few bucks after year or close account (though it could be abused without linking to phone number or email), but for sure ain't gonna pay upfront for deserted app, switching friends/family over takes time... anyway already have plenty people on board Signal, waiting for years for ability to send photos (plural) which it's eliminating everything else making signal just SMS app next to default WhatsApp
