Apps

The apps we build and run.

Each app has its own brand, website, store listings and subscription. All of them are owned and operated by Alt Dev Apps, which means one registered entity is accountable for every one of them: PencilDrop, BubSync and My Energy Agent.

Art & creativity

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.

  • 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

Family & parenting

The shared baby tracker that keeps your village in sync.

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.

  • 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

Energy & household

Energy advice that answers to you.

My Energy Agent is an independent electricity plan finder for households in South East Queensland. It prices the plans available at your address against your own usage, drawing on the regulator’s public plan data, tells you plainly whether a switch is worth it, forecasts the next 12 months, and keeps watching so a plan that stops being competitive does not go unnoticed. It takes no commissions or referral fees from retailers.

  • Prices every available plan against your home’s actual usage, not a headline discount percentage
  • Independent: funded by the people who use it, with no commissions or referral fees from energy retailers
  • Plain-English explanations of tariffs, demand charges and solar feed-in rates
  • Forecasts your costs for the next 12 months and recommends only the plans worth switching to
  • Ongoing monitoring, so a plan that stops being competitive does not go unnoticed

How the studio works

What is shared and what is not

The apps share the studio behind them and the standards we hold them to. They do not share your data, your subscription or your policies.

Shared studio

Every app is built and run by Rowe Digital Holdings Pty Ltd as trustee for the Rowe Digital Trust, ABN 13 313 912 737. One registered Australian entity stands behind all of them.

Shared standards

The same engineering practices, the same privacy posture and the same support commitment apply across the studio, whichever app you are using.

Separate everything else

Each app runs its own accounts, subscriptions, data stores, policies and support address. We do not merge personal data between apps or use one to profile another.

Questions

Questions about the apps

What apps does Alt Dev Apps make?
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), builds and runs PencilDrop (pencildrop.altdevapps.com), BubSync (bubsync.com) and My Energy Agent (myenergyagent.au). PencilDrop is adult colouring with a daily art contest. BubSync is the shared baby tracker that keeps your village in sync. My Energy Agent is energy advice that answers to you.
Where can I download Alt Dev Apps's apps?
PencilDrop and BubSync are on the App Store and Google Play; BubSync and My Energy Agent also run in a web browser. Each app's page on altdevapps.com links its listings, and so does the app's own website.
How much do BubSync and My Energy Agent cost?
Prices are published by each app, on its own website and on its App Store or Google Play listing, never on altdevapps.com. That is deliberate: a plan's price varies by country and by the store it is bought from, so the app's own pricing page is the only place showing the right figure. BubSync: https://bubsync.com/storefront/. My Energy Agent: https://myenergyagent.au/pricing/.
Do these apps share my data with each other?
No. Each app built by Alt Dev Apps runs its own accounts, subscriptions, data stores, policies and support address. Personal data is not merged between apps, and one app is not used to profile a person using another.
Who do I contact for help with one of these apps?
The app's own support address, because that is where the account, the subscription and the people who know the software are: PencilDrop at hello@altdevapps.com, BubSync at support@bubsync.com and My Energy Agent at hello@myenergyagent.au. hello@altdevapps.com also reaches the studio itself.
Are Alt Dev Apps's apps Australian?
Yes. Every app is built and operated by Rowe Digital Holdings Pty Ltd as trustee for the Rowe Digital Trust, ABN 13 313 912 737, from Brisbane, Queensland, Australia. They are designed around Australian rules and supported in Australian business hours.
