Tool achievements: progress you can see, tokens counted honestly

We went through how tokens for the free tools actually work. We found two defects, fixed them, and made the progress visible along the way.

• Progress now shows inside the tool itself. Until now you could only learn about achievements on the Tools page. If you arrived from search straight into the loudness analyzer or the calculator, the gamification did not exist for you. Now a strip appears under your result: which achievement is closest, how much is left, and what it pays.

• There is a single progress screen — in your profile, in the dashboard and on the tools hub. It shows how many checks you have run, which tools you used, your streak of consecutive days and how many tokens you have earned.

• An achievement counts for work, not for opening a tab. Four tools out of five marked usage simply when the page loaded. "Explorer" — four different tools — could be earned by flipping through tabs without checking a single track. The event now counts on the real action: analyzing a file, pressing Calculate, answering in the ear trainer.

• "Regular" no longer depends on the time zone. Days were counted in UTC rather than the Moscow calendar, so ten in the evening and one at night fell on the same day. For people who mix at night the three-day achievement built up slower than promised. A day is now a Moscow day.

• We added short rules, "How it works": what earns tokens, why an account is needed and how much you can earn in total.

A reminder: the free tools can earn you 4 mastering tokens. The reward is credited to an account only — guest progress is not saved.
