Master any words - at any age, in any language. Sight Words: Learn to Read is a vocabulary practice app built around one idea: the more ways you practice a word, the faster it sticks. Six different practice modes keep sessions fresh across weeks and months of daily use. The app ships with complete K-2 sight word lists for school families. But every feature works equally well for adult language learners, homeschool students, or anyone building a custom word deck from scratch. Your words, your language, your pace. ------------------------------ 6 PRACTICE MODES FLASHCARDS Swipe through your word list and rate each word Easy, Almost, or Hard. The app remembers which words need more work and surfaces them more often. QUIZ Hear the word read aloud, then tap the right answer. Works for learners who are not yet reading independently - the app speaks every word. SPELLING Scrambled letter tiles. Tap them in order to spell the word correctly. Every letter and every word is pronounced aloud. SENTENCE FILL-IN Read a real sentence with a word missing. Choose the correct sight word to complete it. Builds reading in context, not just recognition. SENTENCE SPELLING Read the sentence. Spell the missing word from scratch. The most challenging mode - for learners who are ready. SPEED ROUND How many words can you get right in two minutes? Fast-paced, game-like, and great for confidence-building and review. ------------------------------ BUILT-IN WORD LISTS Kindergarten - Dolch Pre-Primer and Primer words across 4 quarters 1st Grade - 120 high-frequency words across 4 quarters 2nd Grade - 107 high-frequency words across 4 quarters All words are read aloud automatically. Pre-readers can practice independently. ------------------------------ CUSTOM DECKS - ANY WORDS, ANY LANGUAGE Build a deck from scratch or import a word list via CSV. Use the app to practice: - A second language vocabulary list - Spelling words from any grade level - Subject-matter terms (science, history, math) - Foreign language flashcards Custom decks work with every practice mode. The app reads your words aloud using text-to-speech in the language you type them in. ------------------------------ PROGRESS TRACKING Every word is tracked individually - Easy, Almost, or Hard. You always know exactly which words have been mastered and which need more practice. Daily streak tracking motivates consistent practice. Progress charts and session logs give you a clear picture of improvement over time. Quarter-based unlocking is optional: enable it to require 80% mastery before the next quarter unlocks, or turn it off for free practice. ------------------------------ BUILT FOR FAMILIES Multiple child profiles - each learner gets their own independent progress and word list. PIN-protected parent settings - children cannot change grade levels, delete progress, or access session logs. Child-selectable accent color themes - learners pick their color and feel ownership of the app. Hoot the Owl cheers with confetti and animations at every milestone. ------------------------------ ACHIEVEMENTS Unlock badges for first word mastered, 7-day streaks, completed quarters, speed round scores, and more. Achievements bring learners back to earn the next one. ------------------------------ PRIVACY Your words and progress are stored on your device and synced privately to your own iCloud account.

COPPA compliant. ------------------------------ FREE INCLUDES Flashcard and Quiz modes for Kindergarten, 1st and 2nd Grade. Up to 2 child profiles. Starter achievements.

Photograph an insect to explore its likely name, identifying traits and life cycle. InsectLens brings those details together with habitat and garden-role information, helping you learn more about the small creatures you notice. Meet the small creature Take a photo or choose one from your library to explore common and scientific names. Compare the identifying features and correct a match when needed. Follow its life cycle Explore its traits, diet, habitat and life cycle. Connect the profile with your own observation. Understand its garden role Read about pollination, plant damage and other effects. Learn how the species fits into the garden around you. Read reported hazards Read about reported bites, stings, irritation and other hazards. Keep the details you want to revisit with your observation. Photograph a bite mark to review possible causes, general care guidance and signs that need medical attention. Photo bite checks share your initial identification allowance and require paid access once it is used; the first-aid card remains free. Keep an observation journal Save an unlocked result, add notes and organize items in folders. Revisit your saved details and identification history as you explore. Learn with 12 guides Read 12 topic guides in step-by-step pages, alongside other in-app articles. No subscription is needed to read the guides. Ask your next question Open the assistant from the result page to ask follow-up questions and keep learning. Usage limits are shown in the app. Read the safety note This is an educational identification and reference tool, not a professional or safety authority. Photo matches can be wrong, and details may be incomplete; missing risk information does not mean safe. Do not use the app to decide whether anything can be eaten or safely handled. Verify important identifications independently and follow local rules. Garden-role information is not a pest-control recommendation for a particular infestation. Bite check results are AI-generated and are not medical advice; bite photos cannot diagnose a condition or reliably identify the insect; do not delay medical care while waiting for a result.
