Questions about pricing
Is the free plan a trial?
No. Free has no time limit, needs no card and shows no ads. It covers everything you need to build and train a repertoire: two repertoires of up to 300 positions, import from your games, spaced repetition, the opening tree, the engine and game review. Pro’s monthly and yearly plans also start with a 7-day free trial, so you can try everything before you pay.
Will free features move behind the paywall?
No. Building, importing and training are the core of Theoria and they stay free. Pro adds capacity on top of them: more repertoires, more positions, deeper lines, the full opening explorer and every endgame.
How much fits in 300 positions?
A full repertoire for one colour. Each position is one move in your tree, so 300 covers your moves and the common replies through the first six or seven moves. An import from your Lichess or Chess.com games usually comes to 180 to 280 positions, leaving room for lines of your own. With two repertoires, most players keep one for White and one for Black.
What happens if Pro ends?
Nothing is deleted. Positions beyond the free limits stay in your tree, visible but locked for training, and unlock again if you go back to Pro.
What does lifetime mean?
One payment of $99.99 and Pro is yours for good, with nothing to renew. Already subscribed? You can upgrade to lifetime from the app.
Does Pro work on every device?
Yes. Pro belongs to your Theoria account, so it follows you between the web app, iOS and Android, along with your repertoires and progress. The price is the same on every platform.
