About SoloSince: Days Since
When did you last change the water filter? Call your parents? Descale the coffee machine?
SoloSince answers one question: when did I last do this?
Add the things you do every now and then. Each one shows a single number — how many days have passed since the last time. Did it again? Tap once, and the count starts over.
It is not a habit tracker. There are no streaks to protect, no goals, no reminders nagging you and no guilt. Just the days since, so you can decide for yourself whether it is time.
WHAT YOU GET
• Every tracker with the days since you last did it, largest number first
• ""Done today"" in one tap, right from the list or from a home-screen widget
• Full history for each tracker, with the gap between every two dates
• Add dates you forgot, change a wrong one or remove it — every change can be undone
• Archive trackers you no longer need and restore them with their history intact
• Search and three sort orders: longest ago, most recent, name
• Home-screen widget for any tracker, with its own ""done today"" mark
• Light and dark theme, and the interface in 34 languages
PRIVATE BY DESIGN
Your trackers never leave your phone. SoloSince has no account, no internet access, no ads, no analytics and no tracking.
SMALL APP, ONE JOB
SoloSince is part of Built by Solo — small apps that do one thing well. It stays simple on purpose: one list, one number per line, one tap to reset it.
