Software that measures, and never retouches.

A passport photo compliance checker. It measures your photo against the official U.S. State Department specification — head height, eye line, background, lighting, expression — and tells you exactly what to fix, in plain English.

What it will never do is alter your photo. No background replacement, no skin smoothing, no AI edits. Modified photos get passport applications rejected; ours checks and crops, nothing more.

• PASSEvery check runs on your iPhone. Photos never leave the device.
• PASSThe full compliance report is free. Pay only to export.
• PASSPixel-exact output for online renewal and drugstore printing.

A weather app that learns what you find comfortable. Log what you wore and how it felt; Daycoat learns your personal comfort window and recommends tomorrow's outfit — thermally right for you, and right for the season.

It never comments on your body or your style. It watches the weather, remembers what worked, and answers one question each morning: what should I wear today?

• PASSLearning happens on your iPhone. Your outfit history never leaves the device.
• PASSYour location goes only to Apple Weather, never to us.
• PASSNo accounts, no analytics, no ads. Free.

One remote for your JetKVM devices and your Windows machines. See the target machine's screen and control its keyboard and mouse from your iPhone or iPad — JetKVM over your local network or through JetKVM Cloud, and Windows PCs and servers over Remote Desktop (RDP). Manage JetKVM settings, firmware updates, and power extension boards from the same app.

Nothing is installed on the machine you control. For JetKVM, JetPilot talks to the hardware, not the computer behind it; for Remote Desktop, it speaks the protocol Windows already has built in. Your device passwords, Windows credentials, and cloud session stay in the iOS Keychain.

• PASSJetKVM direct or via JetKVM Cloud; Windows over Remote Desktop with Network Level Authentication.
• PASSFull keyboard, mouse, and screen control, with clipboard sync for Remote Desktop — nothing installed on the target.
• PASSJetKVM device settings, firmware updates, and ATX / DC power and serial console extensions.

A control panel for the EarStudio ES100 and ES100 MK2. Radsone's own apps are gone from the App Store, but the device still has a ten-band equalizer, analog volume, balanced output modes, DAC filters, codec and battery settings inside it. Earwig reaches them over Bluetooth LE, so a DAC that was headed for a drawer keeps working the way you set it.

Earwig talks only to your ES100. It stores the device's one-time authorization on your phone, needs no account, and has nothing to send anywhere. It is an independent app, not affiliated with Radsone, built on the open-source protocol work of the EarStudio Companion for macOS.

• PASSEqualizer with factory and saved presets, volume, output, DAC, codec, ambient, call and power settings.
• PASSEvery change is read back from the device before the app shows it as applied.
• PASSNo account, no analytics, no network. One-time purchase.

Questions, problems, or refunds — email support@rigwig.org and a human (the one who wrote the app) will reply.
