Guides
Questions, answered first.
Each guide answers one question in its opening sentences, then says what not to do and when to get a person involved. The app is mentioned only where it actually helps.
Speaker Cleaner
- How do I get water out of my iPhone speaker?
Point the speaker down, let the iPhone dry, and only then try a short tone. A tone may help the grille. It will not dry the port.
- iPhone dropped in water, what should I do first?
Get it out, unplug it, and do not put it in rice. Tap the connector downward, wipe it, and let it dry before you charge with a cable.
- Why does my speaker sound muffled after getting wet?
A muffled speaker after a splash is often water still in the grille. Give it time to dry. If it is still muffled a day later, it may be damaged.
- What frequency ejects water from a phone speaker?
Apple does not publish a water-eject frequency for iPhone. A low tone near 165 Hz is a common unofficial choice, and it only has a chance of helping the grille.
Level Tool
- How do I level an RV or camper with my phone?
Use the phone as a rough pitch and roll check, then follow the RV maker's own steps. Phone sensors are approximate and are not the only tool for a setup that affects safety.
- How do I use my iPhone as a level?
Open the Measure app, tap Level, and hold the iPhone to the object. Apple says the reading is approximate. Use a real level for structural work.
Driftly
- Is there a white noise app that works offline with no ads?
Driftly plays white, pink, and brown noise, plus rain and fan sounds, from the iPhone with no ads and no account. It is not a treatment for insomnia.
- White, pink, or brown noise: which is best for sleep?
They sound different, and none is the proven best for sleep. White hisses, pink is smoother, brown rumbles. Evidence that broadband noise improves sleep is weak.
Trove
- How can I identify an object from a photo?
A clear photo can produce a likely name and a value estimate. Both can be wrong. Check them, and never eat a mushroom based on an app or a photo.
- How much is my coin worth?
Date, mint mark, condition, and what buyers actually paid decide a coin's price. An app estimate is a start, not an appraisal. Check sold listings and a dealer if it might be valuable.
Backup Contact Plus
- How do I back up iPhone contacts without iCloud?
Export a contact list as a vCard from the Contacts app and keep that file. iCloud is optional. Export each account, because Gmail and Exchange are separate.
- How do I transfer contacts to a new iPhone?
Use Quick Start or iCloud Contacts if both phones share an Apple Account. If you are not using iCloud, export a vCard and open it on the new iPhone.
Dog Clicker
- Can I use my phone as a dog clicker?
Yes, if the phone plays one short consistent sound and you reward right after it. A physical clicker is easier one-handed. The phone works when that is what you have.
- How do I start clicker training a puppy?
Charge the clicker first: click, then a tiny treat, repeated in a quiet room. Keep sessions to a few minutes. Teach a skill only after the click predicts food.
