Baby Dots
APK
Based on experience with our young daughter, showing sharp contrasting dots along with calming music soothes her. It can take her from a distressed state to happy and content almost immediately. We started showing baby dots from 10 weeks old, and it still worked well at 8 months old. As they grow older, use the child lock so that those little fingers can safely touch the dots as they move around to make them change. Works at home and on the go. Although it may not work for every baby, we hope it helps yours.

Baby Phone
APK
Does your little one like to talk to family and friends on the phone? Do they get sad when there is nobody free to speak with them? Install this pretend phone app to let them listen and speak to another toddler at the other end of the phone babbling back to them. Still in early stages of development. Some ideas for future improvements include: * Record your own audio so your little ones can hear loved ones from their real family. * Interactively listen to the microphone and only babble back when there is a period of silence. * Interact with other phone buttons, such as the dial pad, mute button, etc. Please support further development at GitHub sponsors or Liberapay.

The ELO rating is about 3000 and the program has a unique playing style. In general, the application demonstrates an application of artificial intelligence (AI) into the domain of chess. To clarify, it is not an OEX chess engine and other chess engines cannot be imported into the GUI. Playing instructions: Check the menu and make sure the strength level is appropriate. Select/deselect the Human/Computer buttons for both sides according to which side you want to play and whether you play against a computer or another person. Use the flip board button to change sides if you play with black. Move the piece by drag and drop or by selecting from/to squares. If you want, you could use the move navigation buttons to go back and forward in the move sequence. It is recommended to check all settings in the menu and make sure you play with the option you like most (e.g. move animation speed, chess pieces set, colors). Features: FEN import/export/share. Different modes: Human-Human, Human-Bagatur, Bagatur-Bagatur. Different strengths levels. The app could show the best moves line as well as the evaluation of the board position produced by Bagatur. Navigation of played move's (first, previous, next, last). Flipboard function. Moving by drag and drop as well as by selecting from and to squares. Supports different color palettes and chess pieces sets for different tastes. Permissions: The app uses ACCESS_NETWORK_STATE and INTERNET permsisions, because it shows home ads and they open the default browser on the device, going to one of our other apps' page on the store or on the website of Metatrans Apps. To be more precise, if the other app is available on the store, from which the app is downloaded, then opens the app page of the other app on the same store. If still the app is not available on the store, then opens the app page on our website. The app pages on our website have app demo video on YouTube, so a connection to youtube domain will also be listed in order to visualize the page in the browser. Our website is created by WordPress, so connections to other domains could be opened as well for technical purposes (e.g. downloading text fonts css). Your feedback and/or review is more than welcome.
