Sometimes I wonder how much time I have spent on a meaningful endeavor, or how I can set goals to help myself consistently work towards it. Thus, I build the Prism. Prism allows you to track/set time spending on a project base, with a set of rule-of-thumb time management tools. Hope this little Prism can help you focus on the things you really want to do (it has helped me a lot at least). Feel free to leave a comment on the features you'd like Prism to incorporate!
Little Beaver

Time tracking shouldn’t become another task. Little Beaver Timer is a minimal time tracker inspired by the chess clock. Track just two things: how long you focus and how long you rest. One tap switches states; pause anytime for meals, sleep, or time away. See where your time goes and regain your rhythm. SIMPLE TRACKING • Tap the upper half to rest and the lower half to focus • Just three states: focus, rest, and pause • See today’s focus and rest totals at a glance UNDERSTAND YOUR TIME • Review the last 7 days, last 30 days, or this month • Explore daily timelines, sessions, and focus-to-rest balance • Each tracking day starts at 5:00 a.m. to better match real-life routines TRACK FROM ANYWHERE • Interactive iPhone Home Screen widget • Apple Watch app and watch-face complications • Keep your current state in sync between iPhone and Apple Watch GENTLE REMINDERS • Get a nudge after focusing for too long • Get a nudge when a break runs long • Choose separate reminder intervals or turn them off anytime LIGHTWEIGHT BY DESIGN • No account required • Data stays on your device • Available in English, Simplified Chinese, Traditional Chinese, Japanese, Korean, and Spanish • Free for life Time tracking isn’t about filling every minute. It’s about seeing where your time actually goes. Focus when it’s time to focus. Rest when it’s time to rest. Little Beaver will help you rebuild your rhythm, one twig at a time.
