How many squares to go. A savings record where the target is split into squares and you colour in what you have put aside. - Colour a square, keep a record - Split the target amount into squares - Colour in as much as you have saved, in whatever order you like - Every square coloured shows the target getting closer - Nothing tells you off - No streaks, no consecutive-day counts - Days you did not record are never counted up and shown back to you - The money stays with you - This app does not hold or move money. It keeps a record - The saving itself happens in your own jar or your own account. There is no deposit, withdrawal or transfer feature of any kind - Made to be safe to use - Everything stays inside this device only (nothing is sent anywhere) - No ads - One challenge at a time is free (finish it, and the next one is free too) The more you colour, the closer it looks.
