GIFler is a GIF creation tool with Tumblr and eMail features.
With this app you can easily create animated GIFs. You can email the GIF created or send to Tumblr. For Tumblr the actual number of frames depends on the image size, up to 20. You can set each frame's delay speed individually if desired.
Frames can be added, reordered and deleted. You can save the frames and reload them later.
When you create a GIF you can then publish it to Tumblr for which a Tumblr username is required. You can view your Tumblr dashboard, 'like' blog posts and replay your own GIFs and others from Tumblr. You can also view your own 'likes'. YouTube posts also supported.
With the new eMail feature you can email the GIF from the app and use it anywhere.
GIFler is free, No adverts, No in-app purchases.
