Just as a suggestion which I know would help many trainers out there out with their streaks, It would be amazing if you add a notification that with notify the trainer when his/hers streak is almost over. Maybe make a notification so at around 8 oclock (last chance to spin/catch before turning in for the night) it says something like "Trainer! Your 3rd day streak will end tonight! Last chance to spin another PokéStop to continue your steak!" Obviously you would replace the "3rd" to whatever number they are at, and the "spin another PokéStop" with "catch another Pokémon," depending on what day/requirement to continue the streak. If I had had that notification pop up at like 8 I could continue my streaks. Thanks for the consideration!
