Travel apps organise flights and hotels. Calendar apps organise dates. Neither does both — and neither helps with a birthday or conference full of vendor confirmations. Tagenda does. Forward any booking email and it groups everything into one trip or event. Each booking sits in its own box that turns from grey to confirmed as the email lands — one glance shows what's done and what's missing. Free to start. Pro adds sharing, offline, PDF export, and AI that flags what you still need to book.
