你的伴侣是否在偷偷使用Tinder？
Most "is my partner cheating" tools only check Tinder, are US-focused, and charge $8-15 per single search. PartnerCheck checks 50+ dating apps in one go (Tinder, Bumble, Hinge, Parship, Lovoo, Ashley Madison...), works in German/Italian/French, and costs €19.99. The real differentiator: €39 lifetime monitoring with auto-alerts when a new profile appears. Nobody else offers this. Built for European users who want clarity in 60 seconds, not a 3-week detective contract.
