Travel apps
This is the paperwork category: the visa application you must not get wrong, the entry form the airline will ask for at check-in, the vaccination record a border might want, and the copies you will be glad to have if a bag disappears. Two warnings apply to the whole category. Apply for visas and travel authorisations only on official government sites, and keep an offline copy of anything you would struggle to prove.
The official visa/entry-rule engine airlines use
The public face of the Timatic database that decides whether check-in will board you. Given passport, itinerary and transit info, it states visa and document requirements with official accuracy.
For "do I need a transit visa" on a connecting flight, ask the source the airline checks, not a forum.
The official digital copy of your passport, license and records
When your wallet disappears abroad, this is the only official access to your identity and document records. Passport application/renewal appointments, criminal records and many travel documents come from here.
While handling a lost passport at the consulate, verify your identity instantly via e-Devlet.
Route-based visa and entry requirement summarizer
Enter passport + destination and it neatly summarizes visas, e-visas and entry forms; it also brokers some e-visa applications. Awareness: using the official site it points to is cheaper than the brokered application.
On a three-country tour, summarize what each border will ask on one screen and build your document list.
Shoot the biometric photo for visa applications with your phone
Most e-visa applications want a digital photo to specific measurements; these apps fit your phone photo to the country standard (background, size) and verify compliance.
The India e-visa demands a photo at midnight; shoot against a wall and standardize it in 2 minutes.
The official vaccine and travel-health advisory center
For countries requiring vaccines like yellow fever, appointments are made at Turkey's official travel health centers; the vaccination certificate (yellow card) is issued here. A step not to skip on Africa and Latin America routes.
Book your yellow fever shot 3 weeks before the Kenya flight; show the yellow card at the border without a hitch.
The cloud life-insurance of your passport and insurance papers
A habit more than an app: scanned copies of your passport, visas, insurance policy and card details should sit in an offline-accessible folder. In a loss/theft it shortens the consulate process by days.
Passport stolen: open the photographed copy on your phone at the consulate and start the process the same day.
Reach the application through the government's own domain, typed or reached from an official page, never from an ad or a search result you did not verify. Lookalike sites are legal in most places — they charge a service fee on top of the real one for filling in the same form — and they rank well precisely because they buy the ads. If a site asks for more than the official fee, you are on the wrong one.
