At this point I'm thinking I'll just take a trip to Tenerife to continue learning Spanish.

Other apps aren't good at gamification I hear - and that was the only thing that kept me using it till a while ago. I have ADHD. The leveling up, streaks, etc, is what kept me going when the novelty of learning yet another foreign language wore off - I already had to learn two in school and I only ever really use one of them, you can guess which one.
