Hear2Rise is an innovative flashcard App, where simplicity is King. Unlike other Apps that incorporate images and text, Hear2Rise focuses exclusively on Audio. This simple approach yields powerful results, making the tasks of creating, using, and sharing cards simple beyond compare. Want to learn Spanish? Just dictate the Spanish words and corresponding translation into the App, one after the other, using our simple UI (user interface). Already know Spanish and want to learn French? Just do the same thing, dictate the Spanish word followed by the French translation. Want to learn (or have your child learn) the times table? Again, just dictate your “Challenge” and the corresponding “Response”, and that’s it! You could literally create 20 cards in less than a minute! Once created, your deck is synced to the cloud, making your library available on multiple devices; you can even share your deck with friends. When doing mundane activities like taking a walk or riding a train, you can use our auto-play feature to learn your deck; you can set it to shuffle, continuously loop, and repeat each card multiple times before proceeding. Just set your preferences, press go, and let the learning begin! When reviewing cards one by one, you can mark your mastery of each card as strong, weak, or in between, and then filter your playback by its’ marked mastery level. Each card has a Challenge and associated Response. The application of this is endless. Some examples of decks you could easily create are: • Take a study guide and record the question (Challenge) and the answer (Response). Then play it back to master them. • Learn technical terms • Learn languages • Learn math facts and formulas • Store trivia cards • Memorize theater lines (via Series Mode) • Memorize biology processes like the Krebs Cycle (via Series Mode) • Memorize case law for law school • Memorize chemical equations If you can hear it, you can learn it!

Verdict
The clearest difference is rating: Hear2Rise at 4.0 against OpenGL ES Reference's 3.0. OpenGL ES Reference's advantage is review sentiment (67% vs 50%) and iOS requirement (8.1 vs 13). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Hear2Rise holds the better App Store score, 4.0 against 3.0. Both are backed by a comparable volume of ratings — 3 and 3 respectively.
