SPLIT
Three Ideas

A utility, not a platform.

01

Side by side, not stacked.

Real concurrency, not picture-in-picture. Both apps stay interactive at all times.

02

Pay once. Own it.

$8.99 today, $8.99 in five years, $8.99 forever. No subscription. No tiers. No "Pro+".

03

Built by one person.

Every gesture, every animation, every bug fix — same hands, since 2014. Email reaches the developer.

Inside DuMore 3.0

Seven things, done well.

No feature list arms race. These are the seven things people actually keep DuMore for.

01

Social Plugin

One tap from any tweet, post or thread to a paired browser window. Inline, not modal.

02

Child Lock

Pin the current pair and lock the device. Hand the phone over with nothing else accessible.

03

File Manager

Downloads, screenshots and snippets, all in one place — searchable, sortable, exportable.

04 · Differentiator

Left-hand support, by default.

DuMore is the only split-screen app on iOS with full mirrored layout for left-handed users. Toolbars, gestures, and reach-zones — flip with one switch.

LEFT MODE ON
05

Private Browsing

Either pane, or both. Independent cookies. Independent sessions. Nothing follows you home.

06

Pay Once

$8.99. No upgrade tax. No subscription. v3 is a free update for everyone who bought v1 in 2014.

07

Dark Mode

Tuned for OLED. True black option for battery, soft black for eyes. Per-pane override.

Pay Once.
Own Forever.

For iPad

Built for the big screen.

The same app, twice the canvas. Stage Manager wishes it worked like this — a true 50/50 split, with no system arbitration.

Every line of code in DuMore was written by one person. Every bug you reported, I read. Every feature request, I considered. That hasn't changed. The one-man army is still at it.
