JustConvert review
A paid iPhone converter with offline rates, widgets, clocks, and unit tools.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
JustConvert is an iPhone app for converting currencies, times, and everyday measurements. It supports 120 currencies, cached exchange rates for offline use, world-clock views for cities and time zones, and conversions for temperature, distance, weight, area, and speed. Travelers and people who regularly coordinate across currencies or time zones get a broad utility without creating an account; conversion data stays on the device, with favorites and local history available for repeat tasks.
The paid structure is straightforward but leaves no free entry point. Monthly, Yearly, and Lifetime plans each include all seven converters, so the choice is about billing duration rather than feature gates. Distribution is through Apple's App Store, and pricing or availability can vary by region. For someone who expects to use the currency, clock, and unit tools regularly, the unified plan set keeps the feature scope consistent across subscription lengths and the lifetime option.
Its strongest fit is the iPhone ecosystem: Home Screen and Lock Screen widgets put conversions within reach, while offline cached rates help when connectivity is unreliable. Daily rate refreshes suit reference use, but they are less appropriate for decisions requiring continually updated exchange data. The app also stays focused on solo and small-scale mobile use, with email as its support channel and GDPR listed in its compliance posture. Choose JustConvert for a compact iPhone toolkit that combines currency, time-zone, and unit conversion; choose another option if you need Android or web access, a free tier, or more frequent rate updates.
