Your mind wanders. Unwander brings you back. Random reminders help you notice the moment during the day, and one check-in each evening builds a mindfulness habit. RANDOM REMINDERS Reminders arrive at different moments every day, scattered through the hours you choose. No alarm-clock routine to tune out. The sound stays the same. The words and the times change. Notice it, then carry on. Nothing is recorded. ONE CHECK-IN A DAY Each evening, rate how mindful you were, from lost in thought to fully present, and write a few words about what you noticed. You can change today's check-in until midnight. Past days stay as you left them. YOUR DAYS, IN ONE LIST Your check-ins gather by month, with a preview of each day's words. Daily check-ins build your streak, shown as a single number on the home screen. Missed days are simply blank. PRIVATE BY DESIGN No account, no sign-in, no email. Your ratings, notes and settings live in your own iCloud, where we cannot read them. YOU SET THE HOURS Choose when reminders may arrive and how many you want each day. The times stay random. The daily check-in works even with notifications off. A QUIET CAMPFIRE A quiet campfire plays while you use the app. You can turn it off in Settings. SUBSCRIPTION REQUIRED Unwander requires an auto-renewable subscription after a free trial. Two plans are offered: Unwander Monthly and Unwander Yearly.

Verdict

The call

Short Term Memory's advantage is monetization model (ad-supported vs subscription) and ratings volume (1.1K vs 1). On price, ads and in-app purchases there is nothing between them.
