A warm, clear look at how your phone is doing, and a guided check before you buy a used iPhone. Inside brings together a step-by-step phone check, live system information, importable diagnostic logs, an interactive 3D model and a charging clock. The overview shows battery level, charging state, thermal state, storage and network; the hardware page lists each value with its source. • Used-iPhone check Go through the phone group by group: screen, cameras, audio, sensors and buttons, connectivity, and battery and ownership. Test the display, touch and multitouch, each camera lens the phone has, the flashlight, speaker and microphone, Face ID or Touch ID, proximity sensor, volume buttons, haptics, motion, location, Wi-Fi, cellular, Bluetooth, NFC availability and charging. You perform each test and record what you see. What no app can read, such as battery health, parts and service history, Find My and whether the IMEI and serial match the box, you look up in Settings and enter, and the report marks it as entered by you. Leave and continue later, then share the finished report as an image or text. • Troubleshooting When something looks wrong, save what you saw, follow the troubleshooting steps and test again. Untested, skipped and unavailable items are marked separately and never counted as passing. • Hardware info and diagnostic files Live values show where they come from. You can also import an Analytics log or sysdiagnose to see battery cycles, capacity, display, memory and device records the file contains. Imported data stays separate from live readings, with each field's source and time. What is available depends on the file and iOS version; the original files are never uploaded and serial numbers are masked. • 3D explorer Rotate, take apart and focus on an illustrative model. Supported iPhone models show their own shape, with official colors you can choose; other models use a neutral model. Inner parts and colors are illustrations, not scans. • Charging clock While the app is open it shows the time, battery level and a charging animation, in portrait or landscape. Six clock faces are free; four optional style packs add three faces each, and you can try a pack for 24 hours by watching an ad. Charging history covers only the time the app was in the foreground and can be exported as CSV. • StandBy clock widget Add the StandBy clock widget to your Home Screen or StandBy to keep your chosen face in view; paid faces appear once their pack is owned. • Before you sell Tick off backing up, unpairing Apple Watch, signing out of your Apple Account and erasing the phone, each with a link to Apple's guide. • iPhone Duo Unfolded, the overview stays on the left page while checks, charging and history open on the right. A fold and hinge check follows the opening angle live. Inside is free and shows banner ads. Opening the report image after a finished check may show one full-screen ad, at most once a day; the trial ad plays only when you choose it. A one-time purchase removes banner and full-screen ads. About the data: values iOS does not expose (live CPU temperature, the Settings battery health figure, actual charging wattage and the device color) are never presented as measured. Some part names may come directly from an imported log; unknown codes are not guessed. Thermal state is the level iOS reports. Checks record only this session and your judgement; they cannot rule out intermittent faults or wear and are not a repair diagnosis. ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Remove Ads Forever | $9.99 | one-time | | Woodgrain Theme Pack | $0.99 | one-time | | Night Theme Pack | $0.99 | one-time | | Retro Theme Pack | $0.99 | one-time | | Bloom Theme Pack | $0.99 | one-time | ## Is Inside safe?
