Before choosing a one-time purchase, inspect what the payment actually includes.
Separate the promises
Ask about the included features, supported devices and data access. A purchase label alone does not promise updates or service availability indefinitely.
Check restoration and portability
Purchase restoration restores an entitlement where supported. Exporting a file and importing workout records are separate capabilities to verify.
Do not assume an offer for Weights
The released Weights listing describes monthly and yearly Premium subscriptions. Check the current in-app purchase screen; this article does not advertise a lifetime option.
Check the purchase scope before comparing prices
For each offer, write down the currency, purchase type, included features and supported platform. Distinguish a one-time upgrade from a subscription with an annual price displayed prominently. If the offer says lifetime, read what the seller defines that access to include. Do not infer family sharing, future platform access or every future feature unless those are actually documented. No current one-time Weights offer is asserted here.
Check access and portability separately
Ask whether older workouts remain viewable, whether export is included and what format it produces. Then inspect a sample file if possible. A purchase entitlement and a restorable data backup are separate things: owning access does not establish a recovery workflow. Keep important files somewhere you control, and verify any import or device-transfer behavior before relying on it. Use the current purchase sheet as the source for the offer available to you.
