Best Event Budget App 2026: Birthday, Baby Shower, Surprise Weekend | Partly

Birthdays, baby showers and surprise weekends look small until you add the venue, the cake, the decorations and the group gift. One person floats everything. Then the “we’ll sort it later” thread starts.

One space per event — not per shop

Create a Partly group named after the event. Add organizers, then guests who chip in. Every florist invoice, bakery ticket and grocery run lives in that balance. A new group for each store is how money gets lost.

Event cost buckets

• Venue or Airbnb
• Food and drinks (scan the supermarket + catering)
• Decorations and cake
• Group gift (split only among people who opted in)
• Transport for the guest of honour

Opt-ins matter. The cousin who cannot attend the dinner should not owe the restaurant.

Surprise weekends without spoiling the surprise

The organizers share one private Partly space. Guests who only chip in for the gift can be added later or pay a single payment link. Keep the guest of honour out of the group until after.

Why a notes app is not a budget

Apple Notes and WhatsApp have no running balance, no OCR, no payment request. Splitwise Pro gates itemized scan. Partly scans on free (5/month), keeps 3 groups, and sends links (PayPal, SEPA, Revolut, Lydia, Bizum).

Same-day habit

Photograph every invoice the hour you pay. Assign the group gift to the people who agreed. Settle within 72 hours of the event — energy is still high, excuses are low. Related: hen-do / stag-do budget and weekend cost splits.

FAQ

What is the best app for a birthday or baby-shower budget in 2026?

Partly: one persistent event group, AI receipt scan, and payment links so contributors pay without installing.

How do you split a group gift fairly?

Only include people who opted in. Add the gift as one expense, split equally among that subset, send links.

Can I organize a surprise weekend without the guest seeing the expenses?

Yes — keep them out of the Partly space until after, or use a private organizers group.
