Facts in our reviews were checked between Nov 10, 2026 and Nov 11, 2026.

How we work

• Every claim about prices, limits, policies or numbers links to a source with the date it was checked: official pages, documentation, app stores, press and public user reviews.
• Scores use six fixed criteria (ease of use, features, value, performance, support, privacy) on a 0–10 scale, each with its reasoning. The overall score is the plain average.
• Prices come from official price lists and are never converted. Vietnamese pages prefer VND when the vendor publishes it; other languages prefer USD. Every plan is marked personal, business or API so we never compare different buyers.
• Anything older than 90 days is re-checked, and pages with stale facts show a warning.

About hands-on testing

0 of 451 reviews currently include hands-on testing. The rest are research-based and clearly labelled; they contain no AppDuo measurements. We are testing the most-requested apps one by one, and each tested review records the device, version, plan and testing period, with our own screenshots.

Independence and transparency

• Scores and rankings are not for sale. Affiliate links and sponsored placements are always labelled.
• AI only assists with search, organisation and review; it is never credited as author, treated as evidence or allowed to set scores.
• Mistakes are corrected and logged with a date in each product's change history.
