LispMe is an interpreter for the Scheme programming language developed by Fred Bayer for Palm OS PDAs. It is free software released under the GNU General Public License. It is reasonably close to standard Scheme but is not fully R5RS compliant. Scheme source programs can be stored in Palm OS memopad format while Scheme sessions, are stored in Palm OS PDB database files and can be interrupted and restarted. There is some support for Palm OS user interface primitives.
