Drum Beast is a browser-based drum machine and beat sequencer — no plugins, no installs. You get a classic row-per-instrument layout where kick, snare, hi-hat, and a handful of other voices each get their own track to program independently.

Once a groove feels right, you can record the pattern and export it as a JSON file, which makes it easy to save your work or tinker with the raw data later. It's a focused tool: nothing excessive, just the controls you need to sketch a beat quickly. If you want to go further into generative territory, Orca goes in a completely different direction, building rhythms through a live-coding alphabet grid.

Drum Beast works best on a desktop browser, since the full step grid spreads across the screen and clicking individual cells with a mouse is considerably faster than tapping on a phone.

Tap any element on the periodic table and instantly pull up the details that actually matter: atomic mass, density, electron configuration, melting and boiling points, and more. All 118 elements are color-coded by category, so alkali metals, noble gases, and transition metals each stand out at a glance. A phase filter lets you narrow the table down to solids, liquids, or gases at standard conditions — useful when you're working through a specific concept rather than browsing.

This is a strong companion for chemistry students who want something faster than a textbook and more precise than a search engine. It sits comfortably alongside other education apps built for reference and self-study. If the periodic table is one half of your toolkit, Graphing Calculator handles the math side when equations start showing up in your coursework.

Works best on a tablet or a wide desktop window — the full table layout is easiest to read without horizontal scrolling.

Type a term, flip the card, and decide whether you knew it — that's the core loop in Flash Cards. You build your own decks from scratch, then study them in whichever mode fits the moment: flip-and-rate when you want to move fast, multiple choice when you need a nudge, or type-the-answer when you want to prove you really know it. A spaced-repetition weighting system quietly keeps track of which cards trip you up and brings them back more often, so you're not wasting time on material you've already nailed.

Finished a deck you're proud of? You can share it with the community and pull down decks other players have made — useful when you need to cover a topic fast and don't want to build from zero. If geography vocab is on your list, Atlas Rush covers similar ground with a timed country-naming quiz that makes for solid extra drilling.
