TacticForge

The idea behind TacticForge is not new - Aimchess, Chessigma and a handful of iPhone apps all mine your online games for mistakes - but it is the right idea, and TacticForge executes the part that matters. Link a Lichess or Chess.com username, let Stockfish go through your games, and the missed tactics come back as puzzles tagged by motif: fork, pin, deflection, mating net. The weakness view then ranks those motifs by first-try accuracy, which turns a vague "I blunder too much" into "I miss knight forks in the middlegame". A spaced-repetition queue does the rest, resurfacing each position until it stops being a mistake.

That combination - your own positions, grouped by pattern, reviewed on a schedule - is what separates it from both sides of the market. Generic puzzle sites like ChessTempo do spaced repetition on positions you never played. Lichess's "Learn from your mistakes" works on your own games but one at a time, with no memory of what you missed last week. TacticForge sits in between, and the free tier covers it properly: two game analyses a day, all the training modes, unlimited practice. Premium at $5 a month mostly buys volume and the full opening book built from your repertoire.

The reservations are about the operation rather than the product. The web app has been live since early 2025 and the iPhone version since July 2026, yet there are no ratings, no reviews and no discussion of it anywhere. The terms and privacy policy are boilerplate that names no company - the App Store seller, Code Maker Inc., is the only identifiable publisher - and the site loads session-recording and ad tracking before asking anyone. The "no signup" sample puzzle on the homepage leads to a login page, so trying it means creating an account; this review did not, and describes the training loop from the site and the App Store listing.

For a club player between roughly 1000 and 2000 who plays online and keeps falling for the same tactics, TacticForge is the cheapest way to train on exactly those - and the free tier is enough to find out whether it works for you.
