About JetSetAlarm

Why it exists

Phone alarms think in one clock: the one the phone is in. A traveller thinks in two. You want to wake at seven in the morning where you are, take a pill at nine in the evening home time, and call the office when it opens in another city. When you land, the phone moves its clock and leaves you to work out which of your alarms and doses still mean what you set them for. JetSetAlarm is built around that trip: every alarm, reminder and medication dose knows which city's clock it belongs to, and after landing an arrival review shows each one on that clock so you can keep it or switch it in one sheet.

Who makes it

JetSetAlarm is an independent app made by Alexander Pritsert, who designs, builds and supports it. It is published on the App Store under that name (Apple ID 6758228545). There is no company behind it, no investors and no advertising.

How it is built

• Your data stays on your iPhone. There is no account and no server. Alarms, medications, trips and history live on the device and travel only in your own iPhone backup or a Backup & Restore file you keep.
• It rings like an alarm. Alarms, medication doses and the nap timer use Apple's own alarm system, so they ring through Silent and Focus and show Stop and Snooze on the Lock Screen.
• One price, once. The app is free to use. JetSetAlarm Pro is a single $9.99 in-app purchase with Family Sharing, never a subscription.
• Analytics are off until you say yes. If you opt in, they never include medication names, labels or locations.
• Nine languages. English, Spanish, German, French, Japanese, Simplified Chinese, Portuguese (Brazil), Russian and Ukrainian.

Not medical advice

JetSetAlarm reminds you on the clock you choose; it does not tell you when to take a medicine. Ask your doctor or pharmacist how to time your medication when you travel.
