Do4SA is a Non Profit established to shake off negativity from the mindsets of many South Africans. Poverty is a wall, impossible to demolish as a whole. Your donations remove, brick by brick the wall built by forces that create poverty. The millions we cannot reach should not wipe the optimism of helping the few we can, granting aid to one individual is in effect giving life to humanity.

Verdict
The clearest difference is update cadence: Olarm at every 3 weeks against Do4SA's every 8 months. Do4SA's advantage is iOS requirement (12.0 vs 15.1). On price, ads, in-app purchases and device support there is nothing between them.
