Weekly performance tracking
Nexa chess shows how your play evolves week by week from your Lichess and Chess.com games. Compare your performance, see whether your mistakes decrease, and decide which phase to train.
Compare your performance over time
Weekly tracking summarises your recent activity so you can see whether study shows up in real games: fewer recurring mistakes, better average evaluation, or more stability by phase.
Instead of judging a single bad game, you look at the trend. That avoids overreacting to one weak day and keeps you focused on what is actually improving.
Opening, middlegame, and endgame
Splitting results by phase tells you where to invest time: if the endgame drops every week, it makes more sense to train endgames than to keep drilling openings alone.
Use it together with Stockfish analysis: the engine explains the mistake in each game; weekly tracking confirms whether that mistake keeps showing up.
