The short version
For US users, Levels is the better product on most analytical axes. For EU users, Veri is the only one of the two that actually ships — and it is a polished, capable programme in its own right.
When Veri is the right pick
If you are in an EU market, Veri is the right shape — same job as Levels (consumer CGM coaching with biohacker positioning), at €99–€129/month, with native Garmin and Oura integration, multi-language support and local availability. Levels is not an option for most European users.
When Levels is the right pick
If you are in the US, Levels remains the right shape — the deeper meal-impact analytics, the more accurate sensor, the more mature app. The premium pricing is the cost of the analytical depth; EU readers can keep this comparison filed under "what to know about the cross-border alternative".
