A focus tracker with a finish line. Choose your goals, choose your days, and watch the cocoon open when you get there. No account, works offline, with a widget. Lock in on something for a set number of days, and watch a caterpillar become a butterfly as you do the work. Lockoon is a focus tracker for seasons, not forever. You choose what you will do, how long you will do it, and what counts as done. Then you tick things off each day, and the transformation moves through five stages: caterpillar, spinning, cocoon, emerging, butterfly. A SEASON ENDS A habit app that runs forever has no finish line. Lockoon gives you one. Either you reach your goal and collect a butterfly, or the days run out and you keep credit for what you actually did. Both go into your album. PERFECTION IS NOT THE BAR You decide what share of your scheduled steps counts as done — 80% by default. One bad week does not end a season. REST DAYS DO NOT BREAK STREAKS A goal can run every day, or only on the days you choose. A day that was never on the schedule never counts against you, and the consistency grid shows rest days as rest, not as misses. HOME SCREEN WIDGET Small, medium and large. Tick today's goals straight from the home screen without opening the app. Once everything due is done, the widget shows where your season stands instead — streak, steps against your goal, and the stage you have reached. ONE NOTE A DAY Leave a face — rough, okay or good — and a few lines about the day. Written once, then the day is closed. It is meant to capture how the day actually felt, not to be polished afterwards. YOUR HISTORY, YOURS Finished seasons are archived as butterflies, each in its own colour, with the numbers that produced it. Export everything as CSV or JSON whenever you like. EVERYTHING STAYS ON YOUR PHONE No account. No sign-up. No servers. Nothing is collected and nothing leaves your device. Available in English, Türkçe, Español, Italiano and العربية.
