TVApp
Apple TV · iPhone · iPad · Mac · AndroidWhat is TVApp?
TVApp is a native client for Jellyfin, the free media server. It lets you browse and stream your own movies, shows, and other media from your Jellyfin server on Apple TV, iPhone, iPad, and Mac.
How do I connect TVApp to my server?
On first launch, enter your Jellyfin server's address (for example http://192.168.1.10:8096 or your public URL) and sign in with your Jellyfin username and password. TVApp connects directly to that server — nothing goes through us.
A video won't play or looks wrong. What can I do?
TVApp uses VLC for playback, which handles most formats and codecs directly. If something won't play, first confirm it plays in another Jellyfin client, check that your device and server are on a reachable network, and make sure your server has enough bandwidth for the file. Restarting the app clears most transient playback issues.
Does TVApp support subtitles?
Yes. You can also pre-set your favourite subtitle languages, so adding them during playback is a single step rather than hunting through a list every time.
Are there parental controls?
Yes, protected by a PIN code.
Can I use a remote control?
Yes, on Apple platforms — remote control support is Apple-only, so it isn't available in the Android build.
Does TVApp resume where I left off?
Yes. Playback position is saved back to your Jellyfin server, so you can pick up where you stopped — including across different devices signed in to the same server.
Is TVApp available on Android?
TVApp is currently in beta testing on Android — phones, tablets, Android TV, Chromebooks, and Android XR. See the Android beta instructions below to join the tester group and install it through Google Play.
TVApp for Android — beta test
TVApp is in testing on Android — phones, tablets, Android TV, Chromebooks, and Android XR. Join the tester group to get early builds through Google Play and help shape the release.
You'll need your own Jellyfin server to sign in to and stream from — TVApp is a client for it.
- Join the tester group. Sign in to Google with the same account you use on the Play Store, then join our group: groups.google.com/g/powerslave_tvapp.
- Become a tester. On the same Google account, open the opt-in page and tap Become a tester: play.google.com/apps/testing/com.powerslave.tvapp. Without this step Google Play won't let you install the app, even though it may still show it to you.
- Wait a little, then install from Google Play. Google can take 15–60 minutes to register you as a tester. Then open TVApp on Google Play and install it: play.google.com/store/apps/details?id=com.powerslave.tvapp. It installs and updates like any other app, and you'll get new test builds automatically.
Seeing an install error? That almost always means Google hasn't finished registering you as a tester yet — it's not a problem with your device or the app. Give it up to an hour, then try again from the opt-in page above. Still stuck? Check the Play Store is signed in to the same Google account you joined the group with (tap your avatar, top right), and try clearing the Play Store's cache (Settings → Apps → Google Play Store → Storage → Clear cache).
Being a tester is free and you can leave the group any time. Found a bug or have feedback? Email us.
Map Wanderer
iPhone · iPad · AndroidIs Map Wanderer available yet?
Not yet — it's coming soon for iPhone, iPad and Android. See the listing for what it does.
Does Map Wanderer track my location?
With your permission it uses your device location to show where you are, centre the map, and record a track as you move. That happens on your device and is never sent to us. To draw the map and plan routes, coordinates are sent to the map and routing providers below so they can return the right tiles and routes. You can revoke location access at any time in the Settings app.
Which map and routing services does it use?
MapTiler for map styles, terrain and relief data, and address look-ups; and OpenRouteService for walking, cycling and driving route calculation. Both are covered in the Map Wanderer privacy policy.
Where are my tracks, trails and photos stored?
On your device, under your control — recorded GPS tracks, hand-built trails, markers and any photos you attach. None of it is sent to PowerSlave Developments. Removing the app from your device deletes it, so back up anything you want to keep.
TreeWise
iPhone · iPadHow does identification work?
TreeWise covers 55 species, identified by their leaves, bark and seeds. Each species also shows when it flowers and fruits, so you can narrow things down by time of year as well as by appearance.
Where are my sightings and photos stored?
On your device only. Sightings you log, including any photos you attach, are never sent to PowerSlave Developments — see the privacy policy. Removing the app deletes them, so back up anything you want to keep.
PhotoWise
iPhone · iPadWhat can a child actually do with it?
Five activities. Spot it names what the camera is pointed at, and can be taught new things. Frame it scores a photo's composition out of 100 against a chosen guide. Colours breaks a picture down into its named colours and their proportions. Mirror reflects half a face to build a symmetrical one. Filters tries a look on all or part of the picture. There's also a Show Off mode for demonstrating what it has been taught to someone else.
Does PhotoWise use AI? Where does it run?
Yes, and all of it runs on your device. Recognition uses Apple's built-in Vision classifier — around 1,300 categories — plus a nearest-neighbour match against whatever your child has taught it. Composition scoring uses saliency, horizon detection and Apple's aesthetics model.
None of it is a chatbot or a cloud service. The app ships no model files of its own, contains no networking code, and sends nothing anywhere to be analysed. When your child teaches it something, what gets saved is a numeric fingerprint of the image in a file on the device — not the picture uploaded to train a model somewhere. My Brain lists everything that has been taught and can forget any of it.
Does it need an internet connection?
No. PhotoWise contains no networking code at all — recognition, composition scoring, colour analysis, mirroring and filters all run on the device. It works fully offline.
Where do the photos and the things my child teaches it go?
They stay on the device and are never sent to us. The My Brain screen shows everything that has been taught and lets you delete any of it. The camera stays off until a child picks an activity. See the privacy policy.
Contagion & JetPack
iPhone · iPadWhat is Contagion?
A roguelike raid game with permadeath — you push deeper through brutal levels, and a single mistake ends the run. See the listing.
What is JetPack?
A fast 2D action shooter — pilot a jetpack craft through waves of 18 enemy types, grabbing power-ups as the difficulty climbs. See the listing.
Do the games collect any data?
No. Game progress, scores and settings stay on your device. Neither game contains analytics, tracking or advertising — see the privacy policy.
