It is the studio site for the entity behind the apps. Every app is sold by itself, on its own website and store listings, with its own prices, billing, terms and privacy policy. Prices are never published on altdevapps.com, because they vary by plan, by app store and by country; the app's own pricing page or store listing is the only current source. A charge on a customer's statement carries one of the trading names, the registered entity's name or the store's name, not the name of this website. Help with an app goes to that app's own support address, listed under each app below. hello@altdevapps.com is for the studio itself, and is also PencilDrop's support address. altdevapps.com carries advertising served by Google AdSense and counts visits with Google Analytics; both are disclosed in its privacy policy. An ad on the site is not an endorsement. ## PencilDrop > Adult colouring with a daily art contest. PencilDrop is an adult colouring app with a daily art contest. Everyone gets the same new line-art page each day. Colour it on an iPad, tablet or phone, enter for free, and other people judge the entries side by side, two at a time and without names, so you can see where you place. - Page on this site: https://altdevapps.com/apps/pencildrop - Category: Art & creativity - Status: Live - Runs on: iPad, iPhone and Android tablets and phones - Business model: Free to download, and every competition is free to enter.

You must be 16 or over to use it. - Support: hello@altdevapps.com What it does: - A new page every day, a bigger scene every week and a showpiece every month, and everyone colours the same one - Entries judged by people in pairs, with names hidden, so a first-timer can beat a regular - Global and country leaderboards, season standings and a daily streak worth keeping - Made for Apple Pencil: pressure, tilt and hover, with colour that stays inside the lines of each shape - Turn a finished page into a vertical time-lapse and share it anywhere - No comments and no direct messages, so the art does the talking Questions and answers: - Q: What is PencilDrop?

BubSync is a shared baby tracker for everyone caring for the same child. Parents, partners, grandparents and babysitters log feeds, sleep and nappy changes on their own devices, and every entry syncs to one family timeline. It works offline first, so a 3am log still saves with no signal. - Page on this site: https://altdevapps.com/apps/bubsync - Category: Family & parenting - Status: Live - Runs on: iPhone, iPad, Android and any web browser - Business model: A free tier with basic logging, plus an optional Premium subscription for unlimited children, AI insights, extended history and live notifications. One subscription covers the whole family. Current plans and prices are published on bubsync.com. - Who it is for: Made for families where more than one person cares for a baby: parents, partners, grandparents, babysitters and carers. - Support: support@bubsync.com What it does: - Offline-first logging across eight activity types, from bottle and breast feeds to sleep and nappy changes - Real-time sync to a shared family timeline, with role-based access for each caregiver - AI-generated day schedules, sleep rhythm insights and play suggestions drawn from your own logs - Growth charts for weight, height and head circumference, plus milestone keepsakes with photos - 24-hour handover links that let a babysitter log activity without installing anything Questions and answers: - Q: What is BubSync? A: BubSync is a shared baby tracker made by Alt Dev Apps in Brisbane, Australia. Everyone caring for the same child logs feeds, sleep, nappy changes and more on their own device, and every entry syncs to one family timeline. It works offline first, keeps growth charts and milestone memories, and offers AI insights drawn from the family’s own logs. - Q: Is BubSync free? A: BubSync is free to use, with basic logging for the whole family. An optional Premium subscription adds unlimited children, AI insights, extended history and live notifications, and one subscription covers every caregiver rather than each person separately. Current plans and prices are published on bubsync.com. - Q: Can grandparents and babysitters use BubSync? A: Yes. BubSync is built around shared care rather than one primary parent. Grandparents, babysitters and carers can have their own access on their own devices, and a 24-hour handover link lets someone see and log activity in any browser without creating an account or installing anything. - Q: Does BubSync work offline? A: Yes. Every BubSync entry saves on the device first and syncs when the network comes back, so logging at 3am on a bad connection, or none at all, still works and the shared timeline catches up by itself. - Q: Who makes BubSync? A: BubSync is made by Alt Dev Apps, the Brisbane studio of Rowe Digital Holdings Pty Ltd (ACN 697 515 521) as trustee for the Rowe Digital Trust (ABN 13 313 912 737), which trades as BubSync.
