G Time
Read full descriptionHide full description
G Time is a personal interval timer built around one job: helping you (and the people you're with) leave enough time between whatever you're tracking. Going again too soon is one of the easiest ways for a good night to turn into a bad one. G Time keeps a clear countdown to your next safe interval, tracks who did what and when, and gives you an honest picture of your own patterns over time — so you're deciding with information, not guesswork. WHAT IT DOES • Starts a clear, glanceable countdown the moment you log something, showing exactly when your safe interval is up • Gives every person in your group their own profile, so timers and history never get mixed up on a shared phone • Warns before you go again too early by default, with an optional stricter Hard Block for anyone who wants a firmer stop • Keeps a real history over days and weeks, not just a single session • Notices when a pattern is drifting — more frequent entries, bigger amounts, shorter gaps than usual — and says so in plain language, without judgment • Stays discreet: lock screen notifications never show names or amounts by default, and spoken announcements are off unless you turn them on • Lives on your device by default, with an optional private iCloud sync if you use more than one WHO IT'S FOR G Time is for anyone who wants a bit of structure and a second pair of eyes on timing, used solo or shared across a group on one phone. It's a personal organizer, not a medical device — it doesn't replace professional advice or knowing your own limits, it's just one more layer of structure around timing. There are no ads, no required account, and no analytics trackers. G Time doesn't sell or share your data — full stop.
