As a father, I have struggled every time we needed a new pack of diapers: "Which package should I buy?", "Can I buy directly a bigger pack or is my baby already outgrowing the current diaper size?" These were the questions I asked myself constantly and that is why I have created this app. DiaperCalc is a simple but useful utility for parents that counts how many disposable diapers do you need to have in a specified period of time. The computation is based on the baby current weight and expected baby growth based on percentile curves of pediatric growth charts. Main features: • Computes diaper count and sizes for the selected period of time (up to 3 years of age) • Recommends which packaging is ideal to purchase • Displays chart with expected baby growth • Available to distinguish US and EU diaper sizes • Usable for more than one child • Contains useful tips related to diapers purchases and pre-stocking • Works offline • Light/Dark mode support Enjoy the app and do not hesitate to share your feedback with me!

Never wonder "do I already have this color?" again. FlossLog tracks your entire DMC floss stash and cross-stitch projects — and builds your shopping list for you. 【What You Can Do】 ▷ Floss Stash Log every DMC color you own: number, name, quantity, and a discontinued flag. Status — in stock, low, or out — is calculated automatically from your quantity, no extra tapping. Search by number or name, or filter by color family. Free up to 50 colors. ▷ Built-In DMC Catalog Browse 450+ real DMC colors, check off as many as you like, and add them to your stash in one tap. Can't find a color? Add a custom shade by hand. ▷ Automatic Shopping List This is the part spreadsheets can't do. FlossLog compares what your active projects need against what's already in your stash and shows exactly how many skeins to buy for each color that's short — no manual checklist to maintain. ▷ Projects Track title, fabric, up to three photos, and every color a project uses, with shortages flagged right on the project itself. Unlimited, always free. ▷ Progress Log Log a percentage, a note, and a photo as you stitch, building a dated timeline for every project. Hit 100% and FlossLog offers to mark it complete. ▷ Share Cards Generate a WIP card, a finished-piece card, or a stash card — the stash card even shows a milestone badge when you pass 50, 100, 250, or 500 colors. Share via the system share sheet to Instagram, Reddit, or any app you choose. Free with a small watermark; Pro removes it. ▷ Full Backup Export your entire stash, every project, and every photo as a single ZIP file, and restore it on the same or a new device — no Pro required. 【Who It's For】 · Stitchers who've bought the same color twice (or three times) · Anyone juggling a stash spreadsheet and a separate WIP notebook · FlossTubers and WIP-posters who want a shareable card without building one by hand · Collectors chasing the next color-count milestone 【Your Data Stays on Your Device】 Everything is stored locally on your iPhone. Nothing is uploaded to external servers. No account required. 【Pricing】 · Free: 50 floss colors. Projects, progress logs, the automatic shopping list, and full ZIP backup are unlimited. Share cards included, with a watermark. · FlossLog Pro (one-time purchase): Unlimited floss colors, watermark-free share cards. Pay once, yours forever. ---------------------- Developer: Kore Apps Contact: support@kore-apps.com ----------------------

Verdict
The clearest difference is in-app purchases: Diaper Calc at none against FlossLog's 1. FlossLog's advantage is update cadence (every 2 months vs every 39 months). On price, ads, device support and iOS requirement there is nothing between them.
