FullRecall vs Lumastery

FullRecall helps users retain knowledge through scheduled reviews of question-and-answer pairs. Users can write their own material or import data from collections and other databases. After a review, users rate how well they remembered an answer; the software combines that feedback with prior repetitions to schedule the next review, using a neural network that learns the user's forgetting curve. The free plan has no limit on item count or total database size, but questions and answers are each limited to 8192 bytes and category names to 128 bytes. The PC version supports Unicode, open file formats, images, sounds, and text formatting, and includes backups, statistics, clipboard capture, keyboard controls, and search with regular expressions and fuzzy matching. Users can import tab-delimited Excel exports and ready-made databases from the maker's library. FullRecall can run without installation, including from a USB drive. Downloads are listed for Windows, Linux, FreeBSD, macOS (x86), PocketPC, Maemo, and Android; the listed platforms also include iOS and web. Its FAQ says it helps with remembering knowledge, not understanding it.

Lumastery is a homeschool web app with lessons and adaptive practice in math and reading, plus on-screen science lessons. It is designed for families managing children at different ages and learning levels. Practice difficulty responds to a child's recent answers and can return to foundational skills. A skill is marked mastered at 85% across the last 10 attempts; spaced review revisits skills over time, except arithmetic-chain skills. The Family plan allows a choice of traditional or conceptual math instruction for each child. Listed curriculum includes 238 math lessons, 157 structured reading lessons, and 117 on-screen K–8 science lessons. Science is not lab work; literature has three pilot chapters, writing assignments are a parent-graded pilot, and world languages are not offered. The free plan is described as one child and one daily session. Family is listed at $19.99 a month or $199 per year, with up to four children and unlimited sessions, but checkout is not live and the plan cannot be bought or trialed. The public beta has ended, new registrations are closed, and the app is unavailable to families during its wind-down.
