Track end times for heat, humidity and thermal shock tests that run for hundreds of hours. Pause for interim checks and the end time updates. Records can't be edited. A timer built for long reliability tests that run hundreds or thousands of hours in environmental chambers and thermal shock chambers. "When does this sample finish?" "After pulling it out for an interim check, when does it end now?" The app does the math and keeps track for you. - Every sample at a glance Cards show the time left, progress and planned end time for each sample. Finished samples stand out as "Ready to Remove". - Interim checks built in Pulled a sample out to measure resistance? Record "Pause" when you take it out and "Return" when you put it back. Test time counts only the net time in the chamber, and the planned end moves later automatically. You can add a measurement note when you return it. - Reminders before and at the end Set up to 5 notifications per sample: at the end time, a few hours before the end, or at a set hour after the end (e.g. 8:00 the next morning). Notifications stop while a sample is paused and follow the new end time after it's returned. - Records that can't be altered When you record a removal or abort a test, the sample moves to History, where it can't be edited or deleted. Start and end times, actual time in chamber, pause history and every change made during the test stay on record. - Automatic iCloud backup Your records sync to your own iCloud automatically. If you change or lose your iPhone, just sign in with the same Apple ID and your samples under test and your history are all there. Using more than one iPhone? See the same records on each of them. - For tests like High-temperature storage, damp heat (85°C/85%RH, etc.), thermal shock, temperature cycling, aging and burn-in: long environmental and reliability tests performed under standards such as JIS and IEC. - Pricing - All features are free for one sample under test at a time. - To manage two or more samples at once, buy the one-time Premium upgrade. It's not a subscription, and you will never be charged automatically. - Privacy Your data is stored only on your iPhone and in your own iCloud account. No one else, including the developer, can see it. No ads, no tracking.
