I’ve tested Haiku Deck before and I think it’s wonderful.
For this I downloaded Lensoo and Deck since they work on both Android and Apple.
Lensoo is good to use. I would love to see what the premium package gets you. I don’t know if it’s because I’m dense or if there just wasn’t enough in the informational intro but I had a hard time navigating from one page to the next at first. It also seems as though you can add to the recording but not re-record, which is a pity. We are extremely restricted at work with slide decks we can use and SnagIt is a great tool for making short demo videos with voiceover, so it doesn’t have immediate uses for me, but it’s a great tool with a lot of possibilities.
Deck seems to be much more appropriate to business with the ready-made charts and graphs. I managed to crash Deck when I was playing with it and I doubt I will go back to it (bad omen).
I think Haiku Deck and Lensoo would be the most useful for my purposes – mostly for making things on the fly when I don’t have a computer with me. Both can be used for vetting and testing ideas that I could polish up for later use.
