Send flowers that open on their phone. Pick 3, 7 or 12 flowers, write a message, add a photo or record up to 30 seconds of your voice, then share one link by WhatsApp, Instagram or text. They tap it and watch the bouquet bloom in 3D, flower by flower, with soft music and your words. No app, no account, any phone. Schedule it for midnight on a birthday and see when it's opened. One flower is free; a full bouquet is a one-off €2.99–€7.99.
