A habit tracker with no streak counter. Each habit is a weekly rate, like 4 of 7, plus a monthly allowance of grace days, so one missed day never wipes your progress. Silent by default. Free with unlimited habits, a widget, a heatmap and CSV export.
I built a currency converter app because the popular ones frustrated me. I travel frequently and got tired of XE and other converters that: only show one currency pair at a time, require accounts, load slowly with ads.
So I built Xrateo. You pick your favorite currencies, type an amount, and see everything convert in real time. No login, no clutter.
