I'm in a long distance relationship with my Fiance and we spend a lot of time in each others countries. She hated using my behemoth of a spreadsheet to manage and track visor visa times/trip dates so I set out to make a tool to do that and the idea has evolved from there.
At this point I'm working on getting user validation for my ideas and working on an MVP. It's a collaborative platform for you and your partner with the core features being a date manager where you can plan and manage your date nights, a trip planner where you can plan out all of your trips including the budgeting and itinerary, customizable countdowns, and a reminder engine to tie it all together including random prompts to do something for/with your partner to help with addressing their love language needs.
