BACH app logo

BACH surprised me more than any of the other apps I tested for Galentine's Day planning. Originally designed for bachelorette parties, BACH is secretly perfect for Galentine's Day because honestly, same difference, right? Ladies celebrating together, whether for a bachelorette or Galentine's, creates the same energy and requires the same coordination. 

BACH can take care of it all. 

  • Available on iOS and Android.
  • Free with optional in-app purchases.

Polls, itineraries, and expense splitting


BACH handles all the logistical nightmares that come with coordinating multiple people. You can create polls to vote on dates, activities, or restaurants instead of endless back-and-forth in group chats. The app builds shared itineraries so everyone knows the plan without constantly asking what time everyone arrives. Expense splitting happens in-app, eliminating confusion about who owes what.

Everything stays organized in one place instead of scattered across texts, emails, and forgotten conversations. This matters more than it sounds like it would. I've planned enough group events to know that information gets lost constantly—someone misses the restaurant name, another person doesn't see the time change, and suddenly your carefully coordinated plan falls apart.

🎬 Get streaming subscriptions free with your phone plan

Planning a cozy movie night instead of going out? Some phone plans now include free streaming subscriptions to Netflix, Hulu, Disney+, and more. You could save $15–$30 per month just by switching carriers.

Our guide covers the best plans that bundle streaming services so you can binge-watch guilt-free.

Curated group experiences


The curated events feature sets BACH apart from generic calendar or planning apps. You're not just organizing when to meet—you're discovering activities you wouldn't have found otherwise. Paint-and-sip classes, comedy shows, cooking workshops, and outdoor adventures. The app connects you with experiences specifically designed for groups.

When I saw a hat-decorating event in my area while testing BACH, I seriously considered booking it just for myself. Every activity on this app looks genuinely fun, which makes sense—if you're planning a bachelorette weekend, you're curating experiences that create lasting memories, not just filling time.

For Galentine's Day, BACH works whether you're planning something elaborate or keeping it simple. Use it to coordinate a progressive dinner where your group hits multiple restaurants, organize a day trip with activities and meal stops, or just track who's bringing what to a potluck.

The free version includes all the core planning features—polls, itineraries, and basic expense tracking. Optional in-app purchases unlock additional features, but I found the free tier perfectly functional for most celebrations.

How WhistleOut reviews apps

Our mobile experts scour the app stores, looking for the best new apps for Android and iPhone. Before recommending an app, we use the app for at least one full workday, testing its basic functionality and evaluating whether or not it delivers on its promises.

  • Easy to use
    Great apps simplify your phone. We selected the tools that don't require a complicated instructional manual.
  • Affordability
    The internet is filled with expensive price tags, but we're not buying what they're selling. We leaned into inexpensive, quality apps. Extra points if they're free!
  • Hands-on testing
    We played around with these before recommending them, ensuring they're worth your download.

From there, we weigh the app's pros and cons and then determine whether or not it's a worthwhile download for the wider population of cell phone users.
