Web apps for learning memory techniques and mental skills
Bidcrest Group builds and sells educational web apps for consumers. Each one teaches a set of techniques, such as the memory palace, systems for numbers, names and faces, mental arithmetic or learning texts by heart, and gives you room to practise them. Below you will find the apps and the formats they are made of.
The five apps in our range
Each app has its own page. Read it before buying: it lists the contents, the languages, how access works, the price in US dollars or euros and the conditions that apply.

Inside each app
The parts our apps are built from
Our five apps share one toolbox of formats. The page of each app tells you which of them it contains.
A browser app
The app runs in an up-to-date browser and keeps your own space, your saved lists and your notes in one place.
Lessons that explain the method
Short written lessons walk you through a technique step by step, for example how to set up a memory palace or turn digits into images. You decide the pace.
Material to practise with
Ready-made lists, number sequences, sample faces and names, texts to learn by heart and sums to work out, sorted so you can find them again.
Practice tools
The working part of each app: a palace builder, a number drill, a flashcard deck, a timer for mental arithmetic.
A record of your practice
Calendars and logs show which sessions you have done and what you have saved.
Two ways to pay
Some apps are bought with one payment for an access period stated in advance. The rest work by subscription, renewing each period for as long as you keep it.
Before you pay
Information you will always see first
Prior to payment, every product page tells you: the price and the currency you have chosen (US dollars or euros), whether it is a single payment or a subscription, how often billing happens and how renewal works, how long access lasts, how to cancel, and our rules on refunds and withdrawal.
No two apps are identical. Features, languages, access period, pricing model, billing conditions and the terms that apply can all vary, so check the product page and the checkout page of the app you want before you finish buying.
We take the major credit and debit cards, including Visa and Mastercard. The payment page shows which methods you can use for your order before you confirm it. Paying by card costs nothing extra.
Educational content. Our products teach practical techniques and offer general information and tools. They are not medical, psychological, nutritional, legal or financial advice and do not promise any particular result. For advice about your own circumstances, consult a qualified professional.
In countries and regions under comprehensive sanctions, our apps cannot be bought. The further cases are listed in our Terms of Service.
Bidcrest Group sells only digital products, so there is never anything physical to ship.
