Ok done a bit the reverse as many here: came from Heliboard and tested out FUTO (thanks to this post and some others telling it was great). And indeed, it works pretty well, better than Heliboard, especially in English (~40% of my use on Android - I’m French native speaker so most messaging is in French and I use English for some search, lemmy,…). So that’s say in French, futo is not as good as in English (suggestions are often less accurate than in English) but it’s still better than Heliboard. The swipe works better too (and doesn’t require an external (proprietary) library). The only drawbacks I see until now is the limitation to 3 suggestions in the suggestions bar, with Heliboard there was a 3 dot menu giving more suggestions and the lack of spellchecker.
