It’s extremely easy. Login to your Tonik App and tap onto the Stash tile which can be seen on your Home Dashboard. Select Solo if you are saving by yourself, or Group if you want to invite your friends to save with you.
Upload a picture for your savings goal, enter a specific amount you’re targeting to save, and if you want, you can even set a saving deadline.
Add an initial saving to your newly created Stash if you like, or just the same, you may freely add later.
