Thanks for your feedback, keep it coming. ### 1.0.8 — 2026-08-10 New: make the board yours! Eight color palettes, three border styles and five piece sets — including the classic set you see everywhere. Head to your profile, "Board" row. New icon, built to be recognisable at a glance in search results. The English and Spanish App Store screenshots were showing a French interface. Fixed. ### 1.0.6 — 2026-07-30 The subscription offer now shows up at the right moment: after your first real line learned, once you know what the method is worth — no longer at the end of the intro lesson. The notification request now gets the screen to itself after the first lesson: no more stacked prompts. ### 1.0.5 — 2026-07-26 Clearer lessons. The first-move instruction now explains the gesture — tap the piece, then the square — instead of only mentioning drag and drop. The review arrows clearly show when they are inactive. Redesigned subscription screen. It shows the repertoire that is actually locked: named families — Sicilian, French, Caro-Kann and the rest — with a counter of unlocked openings, rather than a list of selling points. The offer no longer covers the end-of-lesson screen: you see what you just learned first. ### 1.0.4 — 2026-07-22 Chess accuracy pass: dozens of move explanations refined (pins, attacks, pawn structures, bishop pairs) across the Sicilian, Ruy Lopez, Caro-Kann, Alekhine and many more openings. English and Spanish translations aligned with the French source. ## More apps by AGENCE DEBORD EURL - [Simply Chic](https://appshunter.io/ios/app/simply-chic/id1538454907) - [Marolys](https://appshunter.io/ios/app/marolys/id1562326601) - [Sapiro: General Knowledge Quiz](https://appshunter.io/ios/app/sapiro-general-knowledge-quiz/id6757706883) - [Daily Ballast: Affirmations](https://appshunter.io/ios/app/daily-ballast-affirmations/id6793470436) - [UV Hour: Sun Exposure Timer](https://appshunter.io/ios/app/uv-hour-sun-exposure-timer/id6795519654) All apps by AGENCE DEBORD EURL: https://appshunter.io/developer/1538454909 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
