Android App, Create HD GIF

Require proposals for a simple mobile app LWP live wallpaper, giving users a selection of different GIFs for Live Wallpaper display or gallery viewing on both Android and Apple devices. The GIFs are photos (some HD quality) and the user can select from a large gallery of these, I have around 50 premade GIFs which I will provide to you. THis is a free app and there is advertising sw to be installed too, either RevPro or Google Ads. Users will pay for a version without ads and with many more GIFS. The Free version will offer 10 GIFs, the paid version will offer around 50. The paid version will entitle users GIF updates which I will need to update and push out from time to time. Each GIF must be attributed a source back to its designer so will need a transparent button or link placed nicely in a corner. This should be in the corner on a semi transparent link. The app must comply with the Googles quality standards!!

Secondly budget is tight on this project so I have clearly defined project requirements in 3page doc. This will enable you to easily get on with dev and minimise rework etc. If you can fit within the budget guidelines on requirements, then state "YES I can meet your budget" To those developers who bothered to read this far and can comply with the above two 'response requirements', I will send you the tech requirements document. I would like to develop a 12-month partnership with a developer for ongoing maintenance over the next year at least. Thanks
