Stack Testers Revision Friend is the latest addition to the suite of apps developed by the Engineers of CES Environmental Instruments, one of the UKs leading environmental Test Houses. The app has been developed as a revision aid to UK Stack Testers in their preparation for the Environment Agency’s MCERTS examinations. The app provides an ever ready reference source for all the current Level 1, Level 2, TE1, TE2, TE3 & TE4 examinations. The revision is in the form of multiple choice and narrative questions, now providing a broader range of practice material to help you get through your MCERTS examinations. Test results are stored within the app and can be reviewed in the analytic section by a comprehensive progress chart showing the subject areas that need development. The Useful Documents section contains information of the documents needed for examination revision and links to the up to date Method Implementation Documents (MIDs) and Technical Guidance Notes (TGNs) published by the Environment Agency. There are links to web sites providing additional revision information and a helpful image gallery.

Sensory Scribe is here to help you out with a handy recording and instant text transcription tool. Sensory Scribe captures text live from the audio recording and you can use it even when you’re offline or phone is in Airplane mode. Storing the original recording of a live meeting, event, medical appointment or lecture as an audio file is always a good idea. And having an instant transcription of the whole event is helpful for students, employees, family and customers alike. A great new accessibility app. External iPad or iPhone microphone recommended for recording at a distance. Sensory Scribe Mobile turns your iPhone or iPad into a live transcription tool. Record speech, see your words appear in real time, and annotate important moments with color-coded markers -- all processed on your device with no internet connection required. A great new accessibility and productivity app. REAL-TIME LOCAL TRANSCRIPTION Tap record and start speaking. Sensory Scribe Mobile captures audio and performs speech recognition simultaneously, displaying words as they are spoken by any speaker in range. A dual-view display shows finalized text in the main area and live recognition results below, so you always see exactly what is being captured. You can look back at the history of the transcription whilst the recording continues. COLOR-CODED MARKERS Five marker types -- Page (purple), Red, Green, Blue, and Black -- let you tag moments during recording with a single tap. Use them however you like: section breaks, action items, urgent flags, questions, speaker changes or general annotations. Each marker is saved with a precise timestamp. SYNCHRONIZED PLAYBACK Review any individual recording with a visual waveform display (in app purchase option). Words highlight in sync with the audio as it plays. Colored marker indicators appear directly on the waveform, and Previous/Next buttons let you jump between markers instantly. Add, edit, or delete markers during playback to refine your annotations. RECORDING MANAGEMENT Save recordings with custom names. Duplicate recordings for separate annotation passes. Share complete recordings -- audio, transcript, word timing data, and markers -- as a single ZIP archive via AirDrop, Mail, Messages, or any other sharing method. Review any individual recording with a visual waveform display (in app purchase option). PRIVATE BY DESIGN All speech recognition runs entirely on your device. No audio, text, or personal data is sent to any external server. No internet connection is required for recording or transcription. Your recordings are yours alone. BUILT FOR - Meeting recording and instant transcription with decision and action item tracking - Lecture capture with concept tagging for study review - Interview recording with real-time quote highlighting - Personal note-taking for ideas, observations, and voice memos - Field research documentation with categorized annotations Requires iOS 16.6 or later. Works on iPhone and iPad. Sensory Scribe creates a zip file containing the audio file and text transcription, so you can save in the cloud or share. The marker option allows you to tag important points such as change of speakers or actions. If you import that Scribe .zip file into Sensory Scribe for Windows, you can see the markers, the full audio and text transcription for further review. Sensory Scribe doesnt require an account to be created, no login needed and no adverts included. Optional in-app purchase to unlock individual audio recording and transcription review within the app. To review or share the individual audio and text files, open your Files app, unzip the recording zip file and open the individual audio or text file. External iPad or iPhone microphone recommended for recording at a distance.
