***NEW SALE PRICE $24.99 (REGULARLY $34.99)*** ***ADDITIONAL 50% OFF WITH VOLUME / EDUCATIONAL DISCOUNT*** Welcome to the Clusters Complex! Our app targets the ten most complex clusters, including three-element clusters and complex two-element clusters. It includes 968 photographs depicting 88 words, 440 phrases and 440 sentences. Children may select motivating themes based on specific animals, activities and sports. A randomization option presents the photographs in mixed order. Furthermore, children can engage in self-monitoring and view short reward videos if they achieve a high level of accuracy. SLPs have the option to monitor progress through recordings and data collection over time, all of which can be backed up on a computer or emailed. All words in this app were carefully selected for the above complex clusters. Ideally, the targets also include early-developing sounds in the medial or final word position. For instance, among /skw-/ words are “squad,” “squeaky” and “squeeze.” We did not select “square” or “squabble” because the final sounds may distract from the challenging initial clusters. Additionally, the phrases and sentences were judiciously chosen. As much as possible, they are loaded with early-developing sounds so that the child may focus on the cluster target. For example, the /fl-/ phrase “white floppy hat” allows the child to focus on the /fl-/ target because it is surrounded by the early sounds, /w t p h/. Likewise, the /fl-/ sentence “We took a flight to Maine” provides a facilitative context. • Features CC and sCC clusters (/θr-/, /fl-/, /fr-/, /sl-/, /shr-/, /str-/, /skr-/, /spr-/, /skw-/, /spl-/) • English targets – Words (88) – Phrases (440) – Sentences (440) • Colorful photos and videos • Over 30 themes (sports, animals, activities) for students to choose from; each comes with its own customized buttons, backgrounds, and reward videos • Randomization option • Self-monitoring • Progress monitoring • Customized messages for students • Data collection features include audio recordings which can be emailed, backed up to computer, or stored on your Apple device

SpeechSeed

SpeechSeed is calm, parent-led speech-sound practice for the time between speech therapy appointments. It gives families a clear routine without pretending a phone can diagnose a speech disorder or replace a speech-language pathologist. PRACTICE WITH DEPTH • 22 speech sounds and 861 practice words with picture cues. • A six-step ladder: sound, syllable, word, phrase, sentence and conversation carryover. • A sound-specific mirror clue helps the grown-up show where to look or listen. • Native layouts for iPhone and iPad, with Dynamic Type and clearly labelled controls. LISTENING THAT STAYS HONEST • At word level and above, Apple's on-device recognition checks which practice word it heard. • At sound and syllable level — or whenever recognition is unsure — the nearby grown-up chooses Try again, Almost or Got it. • Silence is never counted as a correct attempt, and SpeechSeed never claims to score an individual speech sound like an SLP. PROGRESS YOU CAN SHARE • Weekly practice summaries show days, sessions and parent-reviewed outcomes. • SpeechSeed keeps at most one clear or grown-up-confirmed clip locally per session. Play or compare it in reports, or delete saved clips at any time. • Export a clean PDF or text summary to discuss with a speech-language pathologist. WHAT STAYS FREE • Sound and syllable practice on all 22 sounds. • One complete sound program of your choice, through sentences. You can change that choice once every 30 days. • One daily practice session, progress tracking, reports and when-to-seek-professional-guidance information. • No ads and no account. PREMIUM, ONLY IF IT HELPS Premium opens words through conversation carryover across every sound plus unlimited daily practice. Pay once with Premium Lifetime: it never renews and includes Family Sharing. Or choose a monthly or yearly plan, also with Family Sharing; subscriptions renew automatically unless cancelled at least 24 hours before the period ends, and you manage them in your Apple account settings. Apple shows any trial, eligibility and your local price before purchase. Restore Purchases is in the grown-up area. PRIVATE BY DESIGN Listening uses Apple's on-device mode. The single clear or grown-up-confirmed clip kept from a session stays on the device and is never uploaded. SpeechSeed has no account, advertising or analytics, and its App Privacy label is Data Not Collected. SpeechSeed is an educational practice tool. It does not diagnose, treat or replace professional care.
