Small Mac apps that fix the little things.
One person. No investors, no ads, no tracking, no subscriptions — just native Mac apps made with care. Free to try, honestly priced, and yours to own once you buy.
Real desktop apps for macOS — not a web page in a trench coat.
The apps
FontFetch
Pair fonts, build a palette, and export a 17-page brand guide your client can keep — plus DESIGN.md and CSS. Built on 1,900+ Google Fonts, previewed live.
Markless
A markdown editor with no syntax in sight. Your files stay plain .md; you only ever see the beautiful part — the caret can never touch a hash mark.
Magic Timesheet
Reconstructs your billable hours from what you actually did — file activity, WordPress changes, your calendar. Stop losing time you already worked.
Free to try, honest to buy
Try before you buy.
Every app downloads free from this site — no account, no risk. The small tools run free for as long as you like, with no time bomb and no crippled features; Magic Timesheet comes with a 14-day trial. Take as long as you need to decide.
If one earns a place in your day, it asks — politely, and not often — to be paid for: a few dollars for the small tools, once. Pay it and the asking stops forever, on every Mac you own.
Pay once, own it.
No subscriptions, no seats, no "contact us for pricing." Magic Timesheet took months of work, so it costs real money — once.
Every app is a direct download — buy once and it's yours on every Mac you own, no store account, no subscription, ever.
The studio
Powered by passion (and a little caffeine).
heARTapps is one person — me, Stefanie Herzer, in the Bay Area. I build the Mac apps I want to use: small, fast, native, each focused on removing one specific annoyance from your day.
No venture money means no pressure to bloat them, track you, or hide a feature behind a subscription. Everything is free to try, and every price is on the page, up front. You're not talking to a company — you're talking to me, and I answer email.
