Splat-O-Nym Lite is an engaging, independent vocabulary game that helps students learn synonyms and antonyms through four fun activities: Synonym Splat, Antonym Attack, Context Contest, and Lightning Round. Students enter the game in level one of the Synonym Splat activity and move up and down through levels one through four of the 24 levels included with the full version of Splat-O-Nym and between the four game activities based on their performance. The game keeps track of total points, saves the level and points for up to six students between sessions, and generates a Results report that provides a snapshot of a student's performance in the game after each Lightning Round. In all activities but the Lightning Round, students can switch to listening mode and tap on words they would like to hear read for them. Synonym Splat The student splats (taps on) the synonym for each target word presented earning points for correct answers and losing points for incorrect ones. Splatting the correct synonym for four target words in a level before tapping two wrong answers moves the student to the next level. Tapping a word that is not a synonym for two target words in a level (before splatting correct synonyms for four target words) moves the student down a level. A splatted synonym remains on the screen with its target word for a moment to reinforce the connection between the words. Target words for which the student tapped an incorrect answer come back after a couple of new target words to give the student another chance to splat the synonym. If the student taps an incorrect word again, the synonym remains on the screen for a moment with its target word to help the student learn the correct answer. Context Contest If the student taps a word that is not the correct synonym for two target words in a level, Splat-O-Nym Lite presents the Context Contest. This game gives the student a chance to earn back the points lost on the two wrong answers by popping the bubble of the synonym of a target word as it is used in a sentence. Antonym Attack When the student earns enough points playing Synonym Splat, Splat-O-Nym Lite presents Antonym Attack. In this activity, the student zaps each of three monsters carrying a target word flag by sliding the correct antonym into the horn and tapping it. Tapping on a word that is not the correct antonym for the target word causes the monster to growl and the word to bounce back to the horn. The student slides and taps word options until tapping the correct antonym for the target word. Splat-O-Nym Lite awards points based on the total number of antonyms tapped correctly the first time. Lightning Round Each time the student accumulates 20 splatted target words, Splat-O-Nym Lite presents a Lightning Round with those 20 target words. During the Lightning Round, the student taps as many synonyms as he or she can in 30 seconds. Splat-O-Nym Lite awards points based on the total number of synonyms tapped correctly in 30 seconds.
Verdict
The clearest difference is review sentiment: Splat at 100% against Lexia Core5 Reading's 41%. Splat also leads on iOS requirement (9.3 vs 16.0). Lexia Core5 Reading's advantage is rating (3.5 vs 3.0) and update cadence (every 3 weeks vs every 15 months). On price, ads, in-app purchases and monetization model 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.
Lexia Core5 Reading holds the better App Store score, 3.5 against 3.0. That said, the two scores are not equally well evidenced: Lexia Core5 Reading has 14K ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 41% of Lexia Core5 Reading's written reviews are positive against 100% of Splat's, so the app with the better star average is not the one people write more warmly about.
Lexia Core5 Reading ships an update every 3 weeks, Splat every 15 months. The most recent releases landed on October 31, 2026 and October 24, 2026 respectively.
