Speech recognition is upgraded for clearer transcripts on noisy job sites, and Prentis is quicker to reconnect if your signal drops mid-call. ### 1.0.2 — 2026-08-30 Voice you can rely on with your hands full. This update rebuilds how Prentis speaks: answers start cleanly, play through without stutter or garbled fast audio, and a crash some techs hit when reopening a conversation is fixed at the root. PICKS UP WHERE YOU LEFT OFF Reopen a job and Prentis greets you with a quick catch up of where things stood, instead of sitting silent on Listening. CALLS THAT MATCH THE VISIT Start a service call, maintenance visit, or inspection, or just Ask Prentis, and the conversation opens the way that visit actually starts. SMART GLASSES Pair supported smart glasses with a guided one tap setup, and a live conversation moves onto the glasses the moment they connect. CLOSED MEANS QUIET Swipe the app away and everything stops. No audio, no microphone, nothing left running. CLEANER JOB LIST Job cards are simpler to scan: the accent bar marks your active work and each card shows its visit type. Pricing stays yours. Prentis never quotes a number. ### 1.0.1 — 2026-08-19 Prentis now runs a call the way a senior tech does. It works through the whole system before the money conversation, keeps a running list of what it finds, and brings you one set of findings to take to the homeowner instead of stopping you at the first problem. ONE APPROVAL CONVERSATION Findings get noted as you work and presented together, so you are not walking back to the customer three separate times. When you are ready, Prentis lays out what needs doing today and what protects the system long term, and you take that to the homeowner as one ask. APPROVALS THAT HOLD UP What the customer approved, and when, is kept straight for the whole call. Find something new after work has already started and Prentis treats it as its own conversation instead of quietly folding it into the first yes. A customer who wants to think it over is recorded that way, not as a no. A CLOSE OUT THAT TELLS THE TRUTH Your close out shows the work you actually completed, listed separately from work that was approved but is not done yet. Anything the customer turned down is documented with what to watch for. SMOOTHER ON VOICE Spoken answers play through without dropping out partway. Prentis also stops repeating itself when it has already asked you something. CLEANER UNIT HANDLING Photograph two different units in one go and Prentis asks which one you are working instead of mixing their specs together. Read a measurement out loud and it takes you at your word rather than asking you to take it again. Pricing stays yours. Prentis never quotes a number. ### 1.0 — 2026-08-14 No release notes. ## Related topics [prüftechnik ag](https://appshunter.io/ios/topics/prüftechnik-ag) · [nts informatica srl](https://appshunter.io/ios/topics/nts-informatica-srl) · [bynd incorporated](https://appshunter.io/ios/topics/bynd-incorporated) · [ahlan technologies spc](https://appshunter.io/ios/topics/ahlan-technologies-spc) · [ixcsoft](https://appshunter.io/ios/topics/ixcsoft) · [osiris technology ltda](https://appshunter.io/ios/topics/osiris-technology-ltda) · [prestigia](https://appshunter.io/ios/topics/prestigia) · [veepn corp](https://appshunter.io/ios/topics/veepn-corp) · [sanofi winthrop industrie](https://appshunter.io/ios/topics/sanofi-winthrop-industrie) · [bevagent](https://appshunter.io/ios/topics/bevagent) · [thorntons incorporated](https://appshunter.io/ios/topics/thorntons-incorporated) · [orain technologies sl](https://appshunter.io/ios/topics/orain-technologies-sl) · [dlg tecnologia ltda](https://appshunter.io/ios/topics/dlg-tecnologia-ltda) · [sqella technologies corp](https://appshunter.io/ios/topics/sqella-technologies-corp) · [millertech](https://appshunter.io/ios/topics/millertech) · [pusheen corp](https://appshunter.io/ios/topics/pusheen-corp) · [norwood systems](https://appshunter.io/ios/topics/norwood-systems) · [monnit corp](https://appshunter.io/ios/topics/monnit-corp) · [mycentsys](https://appshunter.io/ios/topics/mycentsys) · [aspentech](https://appshunter.io/ios/topics/aspentech) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
