Between review

Between is a relationship app first and a calendar second, which is why it sits lower on this list despite being built for couples. Its heart is a private messenger for the two of you, with stickers, GIF selfies and free calls, plus a store for photos, videos and notes that stays with you when you change phones. The calendar lets you check each other's schedules and special days, and it calculates countdowns automatically, so the days until an anniversary or a visit are always on show. That suits long-distance couples, who often care more about the next reunion than about grocery lists. Between Plus unlocks themes, love letters, longer voice and video messages and removes ads for both partners, at $2.99 per month, $24.99 per year or $26.99 once for life. The calendar does not document sync with Google, Apple or Outlook, so work schedules will not appear automatically, and there are no chores or shared lists.

Who it is for

Long-distance and new couples who want chat and memories more than detailed scheduling.
