PocketLevel turns your iPhone into a precision spirit level and measurement toolkit. Hang pictures perfectly straight, level shelves and furniture, check slopes and measure angles โ with big, sunlight-readable numbers and pro-grade accuracy. BUBBLE LEVEL Bullseye level for flat surfaces and bar level for walls and frames. The display turns green with a haptic tap the moment you hit level. Adjustable tolerance from 0.2ยฐ to 2.0ยฐ. CALIBRATION Two-step calibration against any reference surface corrects for your phone's camera bump and case โ the number one cause of inaccurate phone levels. Your calibration is saved per orientation. ANGLE FINDER Full 360ยฐ protractor with live readout to a tenth of a degree. Set any angle as zero for relative measurements, and read slopes as degrees or percent โ perfect for roof pitch and ramps. SAVE YOUR READINGS Freeze any reading with a tap and save it with a name, like "Top shelf" or "Table saw blade". BUILT FOR REAL WORK - Big monospace numbers you can read in bright sunlight - Screen stays awake while you measure - No ads, no popups, nothing interrupting your measurement - Works fully offline - All processing on your device โ no data collected PocketLevel Plus subscription is required to use the app. Plans: $2.99 per week with a 3-day free trial for new subscribers, or $24.99 per year.

What Went Wrong?
Read full descriptionHide full description
You asked an AI for something. What you got back wasn't it. What Went Wrong? figures out why and whose fault it actually was. Paste what you asked for, what you got, and what you expected. You'll get a straight answer: whether your instruction was unclear, whether the model ignored it, whether you picked the wrong tool for the job, or whether nothing actually went wrong at all. Then it hands you a better way to say it. WHAT IT DOES โข Reconstructs what you actually meant, not just what you typed โข Names the real cause instead of telling you to "be more specific" โข Writes a repaired instruction you'd never have written yourself โข Tells you when a different tool would do the job better โข Sometimes tells you not to use AI at all RETRY, TOGETHER Tried again? Paste the new result. Your original goal stays sealed, so the retry is measured against what you actually wanted โ no moving the goalposts. You'll see which requirements were met, which slipped, and what to change next. IT LEARNS HOW YOU WORK Over time it picks up what you mean by your own words โ what "premium" or "cleaner" means when you say it. It asks before assuming, and shows you everything it thinks it knows. All of it stays on your device. FIRST CASE IS FREE No account. No sign-up. Bring a real problem and see the whole thing. What Went Wrong? is an independent product and is not affiliated with or endorsed by the AI providers referenced in it. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
