Ratings and reviews

Literally what every caffeine user needs - AND easy to use and understand. Awesome. EDIT: I looked at the sub, it's SOO affordable! And now that I'm subbed, I get another insight that's both AWESOME and CRUCIAL in deciding when and how much caffeine to have: namely, the answer to "what has my average caffeine level at bedtime been, given the numbers I've plugged in?" It's awesome, y'all. Do it. You can change your sleep entirely based on that ONE metric. And currently it's just $2 per year!

"almost all beverages are only included in premium version," no real free version unless you manually enter every detail which defeats the purpose of the app. not even a trial run to test before considering purchasing. The metabolism scale is wrong, even after adjusting it. Half life of caffeine is 5 hours and won't leave your system until at least 10hrs via WebMD. Yet it's showing 1mg still in system 24+ hours later?? Developer is hostile & can't accept negative reviews!!

Thanks a lot! bought subscription, it's really worth it! and thanks for working on updates. Like, the app wasn't working till I installed the last one. Also, seems like design changed a little, the letters got bigger on the "Charts" tab. Keep up the great work!
