Spelliful will be you or your child’s weekly spelling buddy. This app is designed to help you or your child learn their words and test better. The process to achieve this is by doing a repetitive activity (or Spellitivity), to get familiarity of the word, then do a practice with no pressure and finally do a real timed test. You will input your list and record an audio of you saying the word. If you don't want to record your own voice you can turn on the system voiceover to cover that for you. For added challenges you can record the word's definition instead of just word. With the layout of having all your list on the left with your selected list in the middle you can easily choose a list then choose what to do with it, Spellitivity, Test, Edit or Share. *This app makes it really easy for a teacher to create a list and share it with the students/parents. *For the Hearing Impaired, you can add an image or video to each word with the audio or no audio. This is very helpful with video clips for Sign Language. *Spelliful is free to use but is limited. Free users are allowed to have 3 of their own list at a time with 5 words per list, but can import in as many ready made list they would like from Teacher Mode users. You can always combine list to one just to send to the activities. An In-App purchase is in available for .99 cents to Unlimited the app. TEACHERMODE for Sharing List Another In-App purchase is available for $2.99 for Teachermode. This feature lets any user share any list they created with audios only. When using Teachermode just setup a share link in the app. When you share the app will provide you with a share code, that you distribute. This is NOT social media and you are NOT posting to a public platform. Here’s how it works: ADDING WORDS 1st. Add data by tapping the New List button in top right corner. Create a list name or use todays date. Then type your word, tap the record button to record you saying the word, then tap Add Word button. 2nd. Repeat the process for each word. 3rd. When list is done, tap “Save” to save and exit. You can also import in a list with audios by users of the Teacher Mode. This is not affected by the apps limits in free version. You can import as many as you like. LEARNING Choose your list. The list name is stated above the current list of words. Choose between Activity, Practice Test or Test. SPELLITIVITY – The Activity is unscrambling the word and is done in 3 levels. First level, the word is shown and the speaker icon will play that current word you recorded. Drag the letters to form the word. Second level, the word will disappear after 2 seconds. Tap speaker to hear and show word briefly. Third level, no word will be shown. Drag the letters to form word. If incorrect you must try again. Third level data will be recorded and shown in the Progress page, time completed and number of missed attempts. PRACTICE TEST – When you are ready you can take a practice test. Tap to start. Your recorded word will play and you must spell it correctly. After typing word hit Go on the keyboard. You will be notified if right or wrong. There will be no time limit per word and you advance when you get the word right. Practice does not show in Progress Report TEST – Testing is similar to Practice Test, except you are timed. The moment the word is played the clock counts down (duration can be adjusted in Settings). If time expires the next word is in play. After you complete a word it will auto advance to next word, until Test is complete. This Test will show in Progress Report page.
