This is Lightweight’s own comparison of official documentation, not hands-on testing. Strong’s US monthly and annual offers were rechecked 7 October 2026; other feature claims retain their 12 August 2026 evidence. Multiple lifetime and annual offers appear in the US catalogue, so none is shown as a universal lifetime price. Offers vary by store and eligibility. Lightweight’s current US billing-period prices were not independently confirmed. A dash means the exact behaviour was not verified in the cited official sources.
Sources
Strong's official product page, Pro features, template limits, profile widgets, exercise charts, workout and template sharing, CSV export, Apple Watch support and US App Store listing. The US App Store is the source for Lightweight’s current purchase offers; no billing-period price was independently confirmed for this revision. Strong’s monthly and annual figures come from its US store description; its catalogue lists several other offers. Strong is a trademark of its owner; Lightweight is not affiliated with or endorsed by Strong.
