There's an old Indian saying: a dog's tail can never be straightened. No matter how long you hold it down, it curls right back. We're a little like that too. The lessons we most want to live by — be patient, speak slowly, assume good intent — are exactly the ones that keep slipping back into old shape. Roundtail is built for that patient, stubborn work of straightening the tail anyway: not by handing you someone else's wisdom, but by keeping your own words in front of you, day after day, until they start to hold. WRITE WHAT MATTERS Capture a thought in seconds — "speak slowly," "assume good intent," "call your mom." Style it your way with a rich set of fonts, colors, backgrounds, and layouts, so every reflection looks as distinct as it feels. SEE IT EVERYWHERE Add Roundtail widgets to your Home Screen and Lock Screen, or let your words appear in StandBy while your phone charges. One of your reflections, surfaced at random, right where you'll notice it. NOTIFICATIONS ON YOUR TERMS Choose when and how often your reflections reach you. No streaks, no pressure — just a quiet nudge toward what you've decided matters. STAY ORGANIZED Group reflections into categories, search everything instantly, and keep an optional private journal protected by Face ID. PRIVATE BY DESIGN Everything lives on your device and syncs through your own iCloud. No account, no sign-up, no servers — and nothing is ever collected or shared. Your words stay yours. Free. No ads. No subscriptions. The tail may never stay straight. That's not the point. Showing up to straighten it — that's the whole idea.
